"Is ea" or "Is é" ?
I've always been confused which to use in the copula. Could someone please give a explanation on which to use for asking a question and for giving the positive/negative answer or statement.
also how do you pronounce "is ea"? is it sa?
It depends on what you're asking. If you're asking a question that involved a definite noun, such as an é an dochtúir é you would answer with is and the correct pronoun. So here it'd be is é. This is often pronounced as if it were sé. Another example: an tú an múinteoir? The answer would be is mé.
If you do an indefinite one, such as an lacha e, then you use is ea, pronounced sea
