Is επαγγελματική the adjective and επαγγελματίας the noun? So "She is professional" versus "She is a professional"?
Yes :) επαγγελματίας can be either masculine or feminine
Ι was wondering this same thing...based on Theo's answer, it seems the English translation is wrong (unless the Greek words are the same other than being different lexical categories).
I hear επαγγελμάτιας
So do I.
The audio seems to be working fine for me, the ι is accented. Maybe it's just the slight emphasis of the vowel (α) that's confusing you? :/
The vowel before the stress has a slightly higher pitch, then comes the actual stressed syllable on a lower pitch. It confuses me too but I guess we're going to have to get the hang of it.
Is there a difference in pronunciation between γγ and γκ? Generally speaking
No, there isn't.
