Unit - 4

English Grammar

1. What are auxiliary verbs? Explain with the help of examples.

Auxiliary verbs, also known as helping verbs because they help in the formation of tenses, mood and voices of other verbs. Auxiliary verbs therefore, add functional or grammatical meaning to the clause in which they appear. 'To be', 'to do' and 'to have' are the most commonly used auxiliary verbs. For example: the auxiliary 'to do' is needed to ask questions in the present and past simple tenses.. The auxiliary 'to have' is used in the present and past perfect tenses. Some tenses such as the present perfect continuous, consist of more than one auxiliary verbs.

Below are examples of some commonly used auxiliary verbs:

      Do you like German food?

      Does your mother speak English?

      Did you come to school yesterday?

      Why are you talking? You should be listening to me!

      I was having a bath when you called!

      A new annex is being built behind the school.

      Have you done your homework?

      My father has never visited the USA.

      How long have you been living in Germany?

      By this time next year, I will have been learning French for 15 years!

Contracted Verb Forms

The auxiliary verbs are very often contracted. For example, it can be said that I'm playing tennis today, instead of I am playing tennis today. These contracted forms of auxiliary verbs are more likely to be used in spoken forms or informal writing. Consider speaking to someone: Why did you not call me yesterday? and instead: Why didn't you call me? It is obvious that the latter seems more probable and consistent.

Conversely, while writing a report or an essay, it is more appropriate to write the full form without contractions: Why did America not join the war until 1941? (instead of: Why didn't America ...?).

The contracted form of auxiliaries can have multiple forms all of which can be correct depending on the context.

      She's not going to the dance.

      She isn't going to the dance.

      I haven't seen him for ages.

      I've not seen him for ages.

The full form is commonly used in spoken language only when the speaker wants to emphasize what they are saying. e:

      Why don't you call him?

      I have called him.

      I do not want to see him again.

2.     Write a short note on modal verbs.

Auxiliary verbs also consist of another set of verbs called modal verbs or modal auxiliary verbs. These verbs combine with other verbs to describe necessity, possibility, intention, or ability. Modal auxiliary verbs include - must, shall, will, should, would, ought (to), can, could, may, and might.

      You must act promptly.

      Can you speak Spanish?

      I would go if I could afford it.

      He said he might reconsider his decision.

      I ought to visit my family.

      We should get to London before midday.

      May I come in?

Here is a list of some modal auxiliary verbs:

Grammatical behaviour of modal verbs:

Grammatically, modal verbs perform in a different way from normal verbs.

• She might go to class.

• Gallaudet should to build a new computer center.

• My teacher can sign well.

• May I see that? / You mustn't shout.
• I could run a long way when I was younger.

I may have seen him yesterday. You should have told me last week.

3.     What are some common mistakes one makes while spelling words? How can they be rectified?

Figuring out how to spell words is one of the most helpful long-lasting abilities and it fabricates the fundamental establishment that all individuals will require all through their training and life when all is said in done. Figuring out how to spell is significant for other fundamental abilities, including reading and writing. In addition, being acceptable at spelling may affect the future vocations of understudies.

Spelling in English language can be very complicated. Words are often not spelled the way they are pronounced. There are silent letters and invisible letters in various words which make it difficult for one to use correct pronunciation while speaking and write the spelling correctly. Therefore, it is significant to be acquainted with various spelling rules in order to be good at writing in English.

Following are some basic rules that one can follow if they found themselves in a spelling dilemma:

1. Rule 1: Double Consonants

Double consonants can often change the meaning and pronunciation of a word. It’s is difficult to figure out double consonants when a word is spoken, especially if the word has only one syllable. Double consonants can be usually found with words having suffixes added to them.

Example: She dropped her keys on the floor by accident.

Some words can be pronounced as either mono syllabic or bi syllabic.

Example: Blessed are the meek for they shall inherit the earth.

Here the word ‘blessed’ is pronounces as Bless-ed.

Whereas in the sentence below, blessed is pronounced as ‘blest’.

Example: He got blessed by both his father and mother.

2.     Rule 2: “I before E, except after C”

Although this rule got many exceptions it can be used as a general guideline. This rule states that if a word got both I and e in it, then I will come before e. But if the word also has a c before I and e, then the I will come after e.

I before E

Example: This game is a piece of cake.

Except After C

She received a suspicious package on her birthday.

3.     Rule 3: Plural Words

Some words can be changed into plural forms by adding suffixes like ‘s’ and ‘es’. The question remains where to use the ‘s’ suffix and where to use the ‘es’ suffix.

The rule is this: if a word ends in ‑s, ‑sh, ‑ch, ‑x, or ‑z, the suffix –es should be used.

Example: The Genie granted Aladdin three wishes but gave Jaffar only one wish.

For all other kinds of words the suffix ‘s’ can be used.

Example: Jake got three chocolates while Julie got only one chocolate.

There are also a number of words that don’t change spellings when their plural forms are used such as, Moose, fish, sheep.

Also there are a number of words that change their vowels when converted to plural forms such as foot-feet, goose-geese, mouse-mice etc.

4.     Rule 4: The Silent E

Usually the ‘e’ at the end of a word which is preceded by a consonant is silent. This however, does not affect the way the vowel before the last consonant is pronounced. It is essential to be careful while using ‘e’ at the end of a word as it might change the meaning of said word.

Example:

The monkey bit me. Keep your fingers out of the cage: the monkeys bite.

Here the tense of the word ‘bit’ changed after adding the suffix ‘e’.

The addition of ‘e’ might also create a completely different word such as in cut – cute.

While adding suffixes such as –ed, -er, or –est, the silent ‘e’ is usually dropped from the end.

Example: She had blue eyes. She had the bluest eyes I had ever seen.
 

5.     Rule 5: Suffixes to Words Ending With ‘y’

When a suffix is added to a word that starts with E (such as -ed, -er, or -est) to a word that ends in Y, the Y typically will change to an I.

Examples:  Baby – Babies, Cry – Cries, Family –Families.

If the suffix –ing is added to a word ending with ‘y’, the ‘y’ is not removed.

Examples: Carry – Carrying, Cry – Crying

If a word contains two consonants before the ‘y’ one should change the ‘y’ to ‘I’ before adding the suffix ‘ly’

Example: Happy – Happily, Lucky – Luckily.

Words which are often misspelt:

Commonly misspelt English words are some of the most used words that are unintentionally misspelt by users in day to day writing. Although it is difficult to determine which words are more prone to spelling mistakes, words with double consonants, multiple connected vowels, and long arduous words are more commonly misspelt compared to other words.

Below are some of the most commonly misspelt words in the English Language:

The first column represents the correct spelling of the word followed by the mistake commonly made by writers and the last column represents the misspelt form of the word used.

4.     What are some common errors associated with pronunciation of different sounds in English?

There is a great difference in how the words are spelled and the way they are pronounced in the English language. Therefore, it is difficult to ascertain the correct pronunciation of a word by just looking at it the way it is spelled. This often results in mispronunciation. Only by hearing the correct pronunciation from a native speaker one can truly understand how words are supposed to be articulated.

For example, consider the following words – through, cough, though, rough, bough. In these words the pronunciation of the letters –ough varies with each word.

Similarly read, need, believe, machine, receive, we, people, key, quay contain nine different spellings for the same vowel sound in the word “need”.

Below are some commonly made errors with respect to pronunciation and how to avoid them -

THE -ED SUFFIX ON REGULAR VERBS

The past tense of various verbs are formed by adding the suffix “-ed” to the base form of the verb. But Even though all  regular verbs are formed the same way, they might be pronounced quite differently. Depending on the preceding syllable, the -ed suffix can be pronounced in three different ways: /id/, /d/, or /t/.

/ID/

This pronunciation is used when “-ed” is preceded by a “d” or a “t”.

Examples

Need   → needed

End      → ended

Start     → started

Want     → wanted

/T/

Regular verbs that end in a voiceless consonant sound have the /T/ pronunciation. Some common voiceless consonants include: /f/ /k/ /p/ /s/ /t/ /sh/ y /ch/.

Examples

/f/ laugh       → laughed

/p/ stop      → stopped

/sh/ wash       →washed

/k/ like       → liked

/s/ miss    → missed

/D/

Regular verbs having a voiced consonant sound have this pronunciation. Some common voiced consonants are: /b/ /g/ /v/ /z/ /m/ /n/ /l/ /th/ /r/.

Examples:

/b/ grab      → grabbed

/g/ beg      → begged

/n/ listen → listened

/l/ kill → killed

SILENT LETTERS

Silent letters are consonants that appear in a word but are not pronounced. It can be difficult for a non-native speaker to grasp which letters are silent in a word, therefore resulting in errors in pronunciation. For example, There are many English words where the “h” is not pronounced. The same applies to many other consonants. Let’s look at some examples.

Silent H

Although it should be kept in mind that the aspirated “h” in English is always pronounced. Here is a list of words that begin with a silent “h”.

Hour

Honour

Honest

Heir

Herbs

These words containing the silent 'h' usually have a vowel right after 'h' and the actual pronunciation begins from the said vowel.

Silent P

There are a number of words where the first 'p' is not pronounced leading to mispronunciation by non native speakers. Here are those words:

Psychology

Psychiatrist

Pseudo

Pneumonia

Pneumatics

Psalms

Another commonly mispronounced word 'receipt', where the “p” is not at the beginning of the word, is followed by a consonant, but is not pronounced.

There are many other silent letters in English and the only way to recognize them is by practicing their usage. By a general rule, they are consonants followed by other consonants. For example: doubt , subtle , assign , design , knife , knight .

THE STRESS ON DERIVED WORDS

Sometimes the stress passes from a later syllable to the first syllable in some derived forms of verbs. Their visual similarity can be misleading and therefore should be paid close attention to.

Examples

Implant (v) implant (n)

Project (v) project (n)

Upgrade (v) upgrade (n)

5.     Give the rules to avoid common errors with tenses.

Rule 1

A past tense in the independent clause is always followed by a past tense in the subordinate clause.

Example: I found out that she was out of town.

However, there is an exception to this rule. When the independent clause in the past tense, the subordinate clause can be in the present tense if a universal truth is being stated by it. 

Example: The children were taught that honesty is the best policy.

Another exception to this rule is when the word ‘than’ is used in the sentence to introduce the subordinate clause. In this case, the subordinate clause can be used in any tense irrespective of the tense of the independent clause.

Rule 2

If the tense used with the independent clause is in the present or future tense, the tense of the subordinate clause can be in any tense based on what needs to be conveyed.

Example: She is saying that she is alright. She says she is fine.
 

Rule 3

If the independent clause is in the future tense, the subordinate clause is not used in the future tense instead a subordinating clause beginning with when, until, before, after etc. is used.

Example: I will call you when dinner is ready. I shall wait until you return.

Rule 4

When the subordinate clause is introduced with the conjunction ‘that’, the following rules must be followed,

• ‘May’ should be used in the subordinate clause when the independent clause is in the present tense.
• ‘Might’ should be used in the subordinate clause when the independent clause is in the past tense.

Example: We eat that we may live. She tried to live so that he might have a chance at life.

Rule 5

When some phrases such as If only, wish that, what if, it is time are used, the clauses that follow it are always in the past tense.

Example: I wish I could eat another ice cream.

6.     What are antonyms? Explain with examples.

Antonyms are words that carry the opposite meaning to another word. They can be used to show contrast between two things or emphasize a point. Antonyms can be totally different words from their counterparts or can also be formed by adding prefixes to some words.

Below are some examples of antonyms that are commonly used in the English language:

Antonyms formed by changing entire words

Love – hate

Beginning – ending

Ugly – beautiful

Wild – tame

Extrovert – introvert

Antonyms formed by adding prefix –un

Acceptable - unacceptable

Able - unable

Do - undo

Certain – uncertain

Seen – Unseen

Antonyms formed by adding the prefix –in

Decent – indecent

Tolerant – intolerant

Human – inhuman

Curable – incurable

Expressible – inexpressible

Antonyms formed by adding the prefix –non

Sense – nonsense

Essential – nonessential

Flammable – non-flammable

Renewable – non-renewable

Entity – nonentity

Other prefixes used to form antonyms of words are –anti (Thesis - Antithesis), -ill (Literate – Illiterate), -mis (Informed – Misinformed), -dis (Assemble – Disassemble) etc.

For example, "blow up" and "explode" have the same meaning, but "blow up" is informal (used more in speech) and "explode" is more formal (used more in writing and careful speech). Synonyms also provide variety to speech and writing.

Many words in the English language contain more than one synonym. Some examples of Synonyms:

8.     Write a short note on modal verbs and their use.

Auxiliary verbs also consist of another set of verbs called modal verbs or modal auxiliary verbs. These verbs combine with other verbs to describe necessity, possibility, intention, or ability. Modal auxiliary verbs include - must, shall, will, should, would, ought (to), can, could, may, and might.

      You must act promptly.

      Can you speak Spanish?

      I would go if I could afford it.

      He said he might reconsider his decision.

      I ought to visit my family.

      We should get to London before midday.

      May I come in?

Here is a list of some modal auxiliary verbs:

Grammatical behaviour of modal verbs:

Grammatically, modal verbs perform in a different way from normal verbs.

• She might go to class.

• Gallaudet should to build a new computer center.

• My teacher can sign well.

• May I see that? / You mustn't shout.
• I could run a long way when I was younger.

I may have seen him yesterday. You should have told me last week.

9.     What are some common errors associated with the use of prepositions?

The use of prepositions in sentences can be a difficult task. Propositions are sometimes short and very common (e.g., at, in and on), and may have several uses depending on the context, which can make it difficult to know which preposition to use.

Below are some common errors to avoid with prepositions:

1. Temporal Errors

The use of 'in' and 'at' depends on the time of the day. For example, in sentences we always use the preposition “in” with “morning,” “afternoon,” and “evening.” But the preposition 'at' is used when talking about the night:

• Helen goes running in the morning.
• Tim goes running in the afternoon.
• Shirley goes running in the evening.
• Bob goes running at night.

b.     Spatial Errors (In and at vs. To)

The preposition 'to' can be used to discuss journeys (e.g., “I’m going to Tasmania”). But if the word “arrive,” is present in a sentence we use “in” or “at” to describe reaching a destination. For instance:

• She arrived in Tasmania just after lunch.
• He arrived at the restaurant five minutes late.

The use of “in” or “at” typically depends on the destination:

The preposition “in” for cities, countries or other large areas. While the preposition “at” is used for specific places (e.g., a library, a bar, or someone’s house).

c.      Time, Days, Months, and Years (At, On, and In)

Different prepositions are used in different contexts while referring to time in days, months and years.

If a time of the day is being referred, the correct term is “at”:

• The party starts at 9pm.

If a specific day or date is being referred, we use “on”:

• The party is on Saturday.

While referring to a month or year, the correct preposition is “in”:

• We’re having a party in April.

d.     Helping verbs

With auxiliary verbs such as “should” or “must.”, the preposition "of" is used.

• Exception: I should of gone to bed earlier. ✗

However, this is an error. The correct word here isn’t even a preposition.

Rather, the verb “have,” must be used which sounds a bit like “of” when spoken (hence the confusion). Thus, it should say:

I should have gone to bed earlier. ✓

e.     Present Continuous Tense

If something has been happening from a long time, we use “for” when referring to a length of time (e.g., a period of hours, days, or months):

• I’ve been writing for six hours.

But if a specific time is used as a point of reference, we use “since”:

• I’ve been writing since breakfast.

The difference here is that the first refers to a measure of time, while the second refers to a fixed point in the past when the activity began.

f.        Talking About and Discussing

“Talking” and “discussing” are similar activities, so people often treat these words as interchangeable. However, only the preposition “about” must be used after “talking.” For example:

• We’re talking about extreme sports. ✓
• We’re discussing extreme sports. ✓
• We’re discussing about extreme sports. ✗

10. What are some common mistakes associated with articles? How to avoid them?

Common Errors with Articles

     The use of A/An with plural Or uncountable noun:

a fact = OK (singular)

a facts = INCORRECT (plural)

An information = INCORRECT (uncountable)

An advice = INCORRECT (uncountable)

a piece of advice = OK (“piece” is countable)

a pants / a glasses / a scissors = INCORRECT (plural)

a pair of pants/glasses/scissors = OK (“pair” is countable)

a rice = INCORRECT (uncountable)

a grain of rice = OK (“grain” is countable)

a work = INCORRECT (uncountable)

a job / a task / a project = OK (countable)

     The articles ‘A’ and ‘An’ always follow the sound, not the letter

a university (pronounced like you – ni – ver – si – ty)

An umbrella (pronounced like um – brel – la)

a hat (h is not silent)

An hour (h is silent)

An X-ray (pronounced like ex – ray)

An NGO (pronounced like en – gee – oh)

a non-governmental organization (when we say the full words, they start with the N sound)

     The use of A and An without a noun following it.

I am a Japanese. = INCORRECT (“Japanese” is an adjective, not a noun)

I am Japanese. = OK

He is an intelligent. = INCORRECT (“intelligent” is an adjective, not a noun)

He is intelligent. = OK

He is an intelligent man. = OK (now it’s OK because we have the noun “man” after “an intelligent”)

     The use of "The" for Singular or Plural and for Countable or Uncountable nouns, when something specific is being talked about (Not General)

I love pasta. (general)

I love the pasta at that restaurant. (specific)

That store sells furniture. (general)

The furniture in my living room is all new. (specific)

Vegetables are good for you. (general)

The vegetables at the market are always fresh. (specific)

I need advice. (general)

The advice you gave me was very helpful. (specific)

     Use of the article "The" for proper nouns:

• NAMES OF CONTINENTS/COUNTRIES*/STATES/CITIES/STREETS:

We’re traveling around Asia for three months.

I’d like to visit Russia.

Paris is my favourite city in Europe.

Have you ever been to California?

They live on Rosewood Avenue.

*Exceptions: the United States (the U.S.), the United Kingdom (the U.K.), the Philippines, the Czech Republic, the Central African Republic, the Marshall Islands

• COMPANIES & UNIVERSITIES*

My uncle works at Samsung.

Microsoft reported high profits this quarter.

She graduated from Harvard.

New York University is very large.

*Exceptions: If the university’s name BEGINS with “university,” then use “the”:

The University of Pennsylvania, the University of Miami

• LANGUAGES & HOLIDAYS

I’m studying Spanish.

He speaks Italian.

My whole family gets together at Christmas.

The office will be closed on New Year’s Day.

     "The" can be used while referring for certain places:

• DO NOT USE THE WITH INDIVIDUAL LAKES OR MOUNTAINS:

Mount Everest is the highest mountain the world.

We went sailing on Lake Ontario.

• USE THE WITH OCEANS, RIVERS, VALLEYS, DESERTS, MOUNTAIN RANGES, POINTS ON GLOBE:

The Pacific Ocean

The Amazon River

The San Fernando Valley

The Sahara Desert

The Swiss Alps, the Rocky Mountains

The North/South Pole, the Equator

• DO NOT USE THE WITH THE FOLLOWING PLACES:

I’m going home.

She’s at work.

He’s in jail.

We attend church.

My kids went to bed.

My brother’s in high school.

My sister’s in college.

• USE ‘THE’ WITH THE FOLLOWING PLACES:

I went to the bank.

Let’s go to the movies.

He gets home from the office around 7.

My grandfather’s in the hospital.

I’ll stop by the post office after lunch.

I caught a taxi to the airport.

I’ll pick you up at the train station.

We’re waiting at the bus stop.

We took my son to the doctor.

I’m going to the dentist this afternoon. (in this case, “the doctor” and “the dentist” are short for “the doctor’s office” and “the dentist’s office”)

11. What are prepositions? Discuss their various types.

A preposition is a word that connects the noun/pronoun in a sentence to the other parts of the sentence such as the verbs and adjectives. It determines the relationship between the nouns, pronouns and the other words in a sentence.

They help one understand the relationships of logic, space and sequence between the different parts of a sentence.

Below are few examples of prepositions commonly used in the English language:

1. I just came back from the U.S.
2. The book is inside the drawer.
3. The kid threw a stone into the lake.

A preposition cannot be plural or possessive. Sometimes prepositions can also act as nouns, verbs and adverbs.

Types of Prepositions

1. Prepositions of Time:

These prepositions indicate when something happens, will happen or has happened in any point in time.

Prepositions of time include at, on, in, before, during, after.

Examples:

1. John was born on the 7th of August.
2. David left his job in 2012.
3. Amy ate lots of fruits during her pregnancy.

2.     Prepositions of Place:

These prepositions usually indicate the position of a particular thing or person. The three most common prepositions of time are on, at and in.

These prepositions may also indicate the time along with place but depending on their use it can be easily ascertained what they are referring to.

Examples:

1. The ball is in the court.
2. The clothes are on the top shelf.
3. I was at the supermarket just yesterday.

3.     Prepositions of Direction or Movement:

Prepositions of movement indicate the direction in which a person or an object is moving.

‘To’ is the most commonly used preposition of movement.

Examples:

1. I went to shop for groceries but all the shops were closed.
2. He took his dog to the park.

The other prepositions of direction or movement are across, though, over, down, up, past, around.

4.     Prepositions of Manner:

Prepositions of manner describe the way in which things take place or means by which things happen.

Prepositions of manner include by, in, like, with, on.

Examples:

1. I like travelling by car.
2. She went to the school in a taxi.
3. Jacob sings like a professional.
4. He reacted with pity when he saw the poor cat.

5.     Preposition of Agents or Instruments:

Preposition of Agents or Instruments describe the action conducted by a person or object on another person or object.

Most common prepositions of these types are by and with.

Examples:

1. The song was recorded by James.
2. He cuts his hair with a clipper.

6.     Prepositions of Possession:

Prepositions of Possession indicate the owing or owning of an object. It also can be used when something is own to someone. Prepositions of possession include of, with and to.

Examples:

1. This is the car of my niece.
2. He said he saw a man with a green umbrella.
3. This jacket belongs to my grandfather.

12. What are the various types of tenses in the English language? Give examples for each.

Tenses determine whether something has happened, is happening, or will happen. The tense of a verb describes its position in time.

Tenses can be divided into 3 main types and further sub dived into 4 types:

PRESENT TENSES

1. SIMPLE PRESENT TENSE: In this type of tense the action is still taking place, there is no mention of its completeness.

Example: I sleep.
She studies vocabulary every day.

2. PRESENT CONTINUOUS TENSE: In this type of tense the action is still in progress, therefore the use of the word ‘continuous’.
 

Example: I am sleeping.
I am eating lunch, I will call you later.

3. PRESENT PERFECT TENSE: In this type of tense the action has already been completed, hence the use of the word ‘perfect’.

13. What are definite and indefinite articles? How are they used in sentences?

Articles are words that precede a noun and define the specificity of that noun. In other words, they imply how specific a particular noun is.

There are two types of Articles in the English language, Definite and Indefinite Articles.

1. Definite Article

The definite article is the word ‘the’. This article is only used when a particular place, thing or activity is being referred to. It limits the meaning to one particular thing or activity.

For example, in the sentence “I won’t be attending the party this weekend.” ‘The’ is used before the noun party therefore it refers to a specific party which the subject is talking about. The definite article can be used with both singular and plural words.

Uses of “The”:

1. The definite article can be used to make general things specific, for example, “Please pass me a pen.” when changed to “Please pass me the pen.” Changes the meaning of the sentence entirely. In the former the subject requests for a pen in general whereas in the latter he refers to a specific pen.
2. ‘The’ is used by geographical areas such as rivers, mountains, seas, oceans etc.

“The Middle East”, “The Atlantic Ocean”, “The Himalayas”

c.      Unique things always requite the article ‘the’

“The Sun”, “The Moon”

d.     Musical instruments use ‘the’

“He plays the cello.”

e.     Countries generally don’t use articles in front but if their names are plural they use the article ‘the’

“The Netherlands”, “The United States of America”

f.        Abbreviations and classes of people always use the article ‘the’

“The U.N” “The Poor” “The British” “The IMF”

2.     Indefinite Article

The Indefinite Article is of two types, namely, ‘a’ and ‘an’. The word ‘a’ is used when it precedes a word that starts with a consonant and the word ‘an’ is used when it precedes a word that starts with a vowel. Unlike the Definite Article, the Indefinite Articles refer to a general idea and not a particular one. The Indefinite Article only appears with singular nouns. For example in the sentences “I would like a good book to read.” Or “I am craving for an apple pie.” The subject talks about books or apple pies in general rather than a specific book or apple pie.

Uses of ‘a’ and ‘an’:

1. Uncountable nouns cannot use either ‘a’ or ‘an’. For example advice is an uncountable noun, therefore a sentence such as “Can you give me an advice.” Does not make sense. Rather “Can you give me some advice.” Is more appropriate.
2. Jobs use Indefinite Articles

“I want to become a teacher” “My dream is to become an actor”

c.      There are a couple of exceptions to the overall rule of employing ‘a’ before words that start with consonants and ‘an’ before words that begin with vowels. The first letter of the word honour, for instance, may be a consonant, but it’s unpronounced. In spite of the way it is spelled, the word honour begins with a vowel. Therefore, we use an. For example, consider the following sentences:
My mother is a honest woman.
My mother is an honest woman.

d.     When the first letter of a word is a vowel but is pronounced with a consonant sound, the article 'a' must be used. For example:

She is an United States senator.

She is a United States senator.
