"We are students."

Translation: Ми студенти.

Under what circumstances would you use "є" as a copula?

[skstudio]

It is used in set constructs, like "у мене є..." (I have...), in scientific, encyclopedic texts, for example, "Температура в 20 кельвін є необхідною для..." (The temperature of 20 kelvin is necessary for...), or for extra emphasis and formality.

Sounds easy enough. Thanks!
