Question

"I", is plural but how? give reason

Answer 1

the plural of I is we

but how u can consider I as a plural

Answer 2

I is both plural and singular. It is the third person singular. A plural subject uses plural verb whereas singular subject uses singular verb. "i live" is the same as "we live". It doesn't mean that live is plural form when used with i. it is a singular form which happens to be same as plural form.
