should

[tanuki]

Hello, all!

How are you doing?

I have a grammar question. How do you say someone "should" do something? Like, for example, "you should study" or "she should speak with him", etc.

I've been looking for the answer on the web, but I really don't know what the grammatical name for that structure is, so I've had no success. I hope you can help me.

Thanks a lot in advance! Bye!

Another commonly used one is 〜ばいい（です）.

Literally it means "if you ______ it will be good".

勉強すればいいよ - You should study, you know.

彼に話せばいいかしら - (She should) probably talk to him.

This type of phrase is most used for giving/asking advice.

Another common example:
どうすればいいかな - I wonder what I should do
