===Comparison of the existential verb and the copula===
Both the existential verb and the copula may take a nominal predicate, but the two constructions have slightly different meanings: {{Lang|ga|Is dochtúir é Seán}} sounds more permanent: it represents something absolute about Seán; it is a permanent characteristic of Seán that he is a doctor. That is known as an '''individual-level predicate'''. In the sentence {{Lang|ga|Tá Seán ina dhochtúir}}, one says rather that Seán performs the job of a doctor, he is a doctor at the moment, or he has become a doctor. That is known as a '''stage-level predicate'''.
