Lesson 006

Greek Course

I think you should use the Duolingo greek course instead, but here are my notes on an alternative.

singular plural
1st μου μας
2nd σου σας
3rd του (masculine)
της (feminine)
του (neuter)

Possessive form of personal pronouns

They are also described as the genitive forms of the pronouns, so:
το βιβίο μου = this book of-me
τα βιβία μας = these books of-us

These follow the gender of the owner and not of the owned thing, so της means of her.

singular plural
1st είμαι είμαστε
2nd είσαι είσαστει or είσει
3rd είναι είναι

Verb "to be" for we are and you are forms. The I am and he / she / it is forms were introduced earlier.

Travel-useful word:
τωρα — now

Calling or addressing someone with the vocative case. We might say This is Andreas — Αυτό είναι Αντρέας, but if we want to address or call him, we drop the -ς (and form the vocative case). Αντρέα! Similarly, we could speak of a man this way:
Αυτό είναι ο κύριος Παυλίδης.
But we would ask him a question this way:
Έχετε ένα μολύβι, κύριε Παυλίδη;

Imperative forms. With no real explanation, imperative forms are introduced.

Count! — Μέτρησε!
