I wish I . . . . . . . a millionaire.

When we are going to pretend something, which is not in actual, we use plural form of verb.

I wish I were a millionaire. Were is plural verb form.

Must be were

Must be were

I wish i were a millionaire, we used plural with I incase of wish

It must be were

Were is the right answer

Why were not used here?
Please guide

Right Answer-Were

Were

I think it would be "were" showing desire

i think were will be used instead of was

Were

it must be were. we cannot use auxiliary was according to wish

Answer should be were, but was in which logic.

I wish I ....(be) a millionaire

it is imaginary sentence answer must be Were

Were

Ans is were

Should be were, unreal situation
