"The eagle drinks water."

Translation: Ο αετός πίνει νερό.

[Lng52-._]

Could you also say it this way: "το νερό ποτά αετός"?

[mizinamo]

ποτά is a noun -- "drinks, beverages" in the sense of "would you like some drinks?" or "alcoholic drinks are bad for you". Plural of ποτό. I don't think there's a noun form ποτάω that this could be the "he, she, it" form of.

Also, αετός by itself is not a good translation of "the eagle".

Why is it Ο instead of το?

[mizinamo]

Because αετός is masculine, not neuter.

So you need the masculine nominative definite article ο, not the neuter nominative definite article το.
