"Αυτή είναι το αφεντικό μου."

Translation: She is my boss.

[JenniferMarot]

Is it not possible to say "this is my boss"? Perhaps if you were introducing her to someone? I put this and got it marked wrong.

[Hafizen]

I agree. That is a very common phrase used to introduce one's boss without mentioning gender.

[G.Georgopoulos]

This is my boss=Αυτό είναι το αφεντικό μου.

[Nekomanna]

Το αφεντικό is masculine, but this boss is a woman. Why shouldn't this be a feminine form?

[troll1995]

"Το αφεντικό", as you wrote has the "το" article, so it is neuter. But, there are some professions that stay the same in masculine and feminine forms. For example ο/η γιατρός, ο/η δικαστής etc. ;)

Why is chief wrong? I am not a native English speaker, is there a difference between chief and boss?

[G.Georgopoulos]

It's better to use "αρχηγός" (which also means "captain") for "chief".

[LadyRovina]

I hear "afentiko", not "afediko". Is there any rule, how can I undestand which sounds to use? when ντ is "d" and when "nt"?

[G.Georgopoulos]

There's no "nt" sound in Greek, it's either "nd" or "d" and always "d" at the beginning of a word.
