"We have a girl."

[AmyPeatlin]

why is ενα and not μια used in this sentence?

[troll1995]

Κορίτσι is a neuter noun (neuter nouns use ένα), not a feminine one (which would use μία/μια). Grammatical gender does not always match natural gender. ;)

Fantastic, thanks for that! After I posted I thought it might be something like that (as it reminded me of some of the things I learnt in Ancient Greek)

[mizinamo]

In case you're curious, many noins in -ι come from diminutives in -ιον (e.g. το παιδί was from earlier το παιδίον, a diminutive of ο παις, του παιδός).

I'm new to Greek, so pardon me if this is is an elementary question, but what is the difference between το κορίτσι and μία κοπέλα?

Why is Εχουμε ενα ηαιδι not acceptable?

[mizinamo]

There is no Greek word ηαιδι, and the word παιδί (with pi instead of eta at the beginning) means “child”, not “girl”.
