The verb to be in English maps to two different verbs in Gaelic. One of these two verbs is Bi, the present tense of which is tha. Conjugating tha with the personal pronouns yields:
Tha thu You are (informal)
Tha e He is
Tha i She is
Tha sinn We are
Tha sibh You are (formal)
Tha iad They are
Tha is used in constructions linking a noun to a condition, e.g.:

Very good. Now we will look at the negation of tha. To express this we use chan eil and so conjugation yields:
Chan eil thu You are not
Chan eil e He is not
Chan eil i She is not
Chan eil sinn We are not
Chan eil sibh You are not
Chan eil iad They are not
Nach eil thu Are you not?
Nach eil e Is he not?
Nach eil i Is she not?
Nach eil sinn Are we not?
Nach eil sibh Are you not?
Nach eil iad Are they not?
A bheil thu Are you?
A bheil e Is he?
A bheil i Is she?
A bheil sinn Are we?
A bheil sibh Are you?
A bheil iad Are they?
Here are some more sentences:
A bheil thu sgìth? Chan eil, chan eil mi sgìth.
lit: Are you tired? Am not, I am not tired.
Are you tired? No, I am not tired.
Nach eil i fluich? Tha, tha i fluich agus fuar.
lit: Is she not wet? Is, she is wet and cold.
Is she not wet? Yes, she is wet and cold.
Note that the response to the interrogative, either negative or positive, is the appropriate form of the verb. There is no form of yes or no in Gaelic.
Nach eil Seumas sgìth? Chan eil ach tha e fluich agus fuar. Is not James tired? No but he is wet and cold.
A bheil Seumas fluich? Nach eil e tinn? Is James wet? Is not he sick?
Tha an cù mór agus an cat bàn anns an taigh. Tha iad tioram. The big dog and the fair-haired cat are in the house. They are dry.
Nach eil an cu dubh luath? Chan eil, chan eil e luath. Is not the black dog swift? No, he is not swift.
