I have a very basic question on conjugation.
If I wanted to say something like "Yesterday was hot" do I conjugate the adjective into past tense, the verb, or both of them? Or do I conjugate the adjective the way I normally would when it is followed by a verb?
Basically, I don't know if I should say "Kinou wa atsukatta desu" or "Kinou wa atsui gakusei datta" or something else. Or, am I completely wrong?
Thanks in advance.
