Positive statement: I play, He plays
Negative statement: I do not play (I don't play), He does not play (He doesn't play)

Negative questions: Do you not play? (Don't you play?) Does he not play? (Doesn't he play?)
Negative questions normally express a surprise.
Doesn't he work?
If the wh- pronoun introducing the question (who, which) is the subject of the question, we do not use the auxiliary verb do. Compare the following sentences.
Who knows you? (who is the subject)
Which cars belong to you? (which cars is the subject)
Who do you know? (who is the object)
Which cars do you like? (which cars is the object)
The third person singular
We use -s ending (plays) and -es ending (goes) in the third person singular.
Peter plays tennis.
My son goes to primary school.
In questions we use does in the third person singular + the bare infinitive (= play, not plays).
Does Peter play tennis?
We add -es to the verb that ends in ss, sh, ch, x and o.
miss - misses, fix - fixes, go - goes
If the verb ends in a consonant and -y we change -y into -i and add -es.
carry - carries, try - tries
But play - plays, because it ends in a vowel and -y.

The verb to be has completely different forms.
Positive: I am, you are, he - she - it is, we are, they are
Short forms: I'm, you're, he's, she's, it's, we're, they're
I am from India. He is ill. They are funny.

Questions: Am I? Are you? Is he - she - it? Are we? Are they?
