Could you shed some light on the meaning and function of indefinite articles before the names of jobs?
I know that when we say, for example, I need a pen this means that I need just one pen and any pen i.e not a specific one. But what about a sentence like the one below.
He is a builder . Does the "a" here have the same meaning as the "a" in my earlier sentence?
I wish I could make myself clear.
