So is εμαί conjugated the same for third person singular and third person plural?
Ναι it is because I am Greek i'm not lying I just want to learn more Greek.
Is there any way to know whether the accent in words ending in a stressed syllable, like παιδί, will move to the additional vowel in the plural, like in παιδιά?
Yes. If it ends in a stressed iota, it will move. If not, it won't.
However, if it ends in an unstressed iota, it will move to the end in the genitive case, e.g. το σπίτι - του σπιτιού - τα σπίτια - των σπιτιών.
(Certain other single-syllable words also have a stressed genitive case in the singular and/or plural if those forms have an additional syllable, e.g. το φώς - του φωτός.)
How do I pronounce παιδια? It sounds like thathia but I thought it was pronounced like padia? I had Koine Greek before taking this course so I am sort of confused. Thanks!
First syllable is like "pet" without the -t, second syllable is the accented one. (And it's just two syllables, not pe-dhi-A.)
The delta is pronounced like the "th" in "this, that, the", and the iota here is a glide like the "y" in "you" or like the first part of English "long u" (beauty = "byooti" -- that "y" glide sound). pe-thya.
I remember someone saying it is like in the English word millions we pronounce it mill-yons.
Your question can be answered by using the facilities provided in the course. The audio here is very clear. The first skill has an analytical explanation of the alphabet and its pronunciation see Tips&Hints at the top left. A glance at the Koine Greek pronunciation here will show that the Ππ is pronounced the same as in the modern Greek taught here. Hope that helps.
