What are auxiliary verbs?
Auxiliary verbs are also called helping verbs because they help the main verb to form different tenses, moods, or voices. For example:
I am working on a project. (am helps to form the present continuous tense)
She can speak three languages. (can helps to express ability)
He was seen by a witness. (was helps to form the passive voice)
In English, there are three main types of auxiliary verbs: be, do, and have. They can also be combined with other verbs called modal verbs, such as can, could, may, might, must, should, will, would, etc. For example:
I have been studying for two hours. (have and been help to form the present perfect continuous tense)
You should have told me earlier. (should and have help to express regret)
They would be happy if you came. (would and be help to form the conditional mood)
What is the role of do and does as auxiliary verbs?
The auxiliary verbs do and does are mainly used for three purposes: forming negatives and questions in the present simple tense, adding emphasis in affirmative sentences, and expressing agreement or disagreement.
Forming negatives and questions in the present simple tense
The present simple tense is used to talk about facts, habits, routines, preferences, etc. For example:
I live in London.
She likes chocolate.
We work from home.
To make a negative sentence in the present simple tense, we use do not or don't before the main verb. For example:
I do not live in London.
She doesn't like chocolate.
We don't work from home.
To make a question in the present simple tense, we use do or does before the subject and the main verb. For example:
Do you live in London?
Does she like chocolate?
Do we work from home?
Note that we use does for the third person singular (he, she, it) and do for the others.
Adding emphasis in affirmative sentences
Sometimes, we use do or does in affirmative sentences to add emphasis or to show contrast. For example:
I do like chocolate, but I can't eat too much of it.
She does work hard, but she also knows how to relax.
We do have a car, but we prefer to walk.
In these cases, we stress the word do or does when we speak.
Expressing agreement or disagreement
We can also use do or does to express agreement or disagreement with a statement. For example:
A: I love chocolate. B: So do I. (agreement)
A: She works hard. B: So does he. (agreement)
A: We have a car. B: So do we. (agreement)
A: I don't like chocolate. B: Neither do I. (agreement)
A: She doesn't work hard. B: Neither does he. (agreement)
A: We don't have a car. B: Neither do we. (agreement)
A: I love chocolate. B: I don't. (disagreement)
A: She works hard. B: She doesn't. (disagreement)
A: We have a car. B: We don't. (disagreement)
How to use do and does correctly?
To use do and does correctly, you need to follow some rules and avoid some common mistakes. Here are some tips to help you:
Rules for using do and does with different subjects
The most important rule is to use does for the third person singular (he, she, it) and do for the others. For example:
I do my homework every day.
You do your homework every day.
We do our homework every day.
You do your homework every day.
The dog does its homework every day.
The cat does its homework every day.
The teacher does his/her homework every day.
Spelling and pronunciation of do and does
To spell do and does correctly, you need to remember that when you add -s to a verb that ends with -o, you need to add -es instead of just -s. For example:
I go to school.
The dog goes to school.
I do my homework.
The cat does its homework.
To pronounce do and does correctly, you need to remember that the final -s or -es sounds like /z/ when the verb ends with a voiced sound (a sound that makes your vocal cords vibrate). For example:
I love /lʌv/ chocolate.
The dog loves /lʌvz/ chocolate.
I play /pleɪ/ football.
The cat plays /pleɪz/ football.
The final -s or -es sounds like /s/ when the verb ends with an unvoiced sound (a sound that doesn't make your vocal cords vibrate). For example:
I like /laɪk/ chocolate.
The dog likes /laɪks/ chocolate.
I watch /wɒtʃ/ TV.
The cat watches /wɒtʃɪs/ TV.
