How do you tell someone you want them to do something in Japanese?

Question

I know how you say you want to do something, just add -tai, right? ^_^ Right! Is it the same for another person you're talking to? Is it the same when asking them if they want to do something? Thanks in advance!

Answer 1

-tai is "I want to"
-te hoshii is "I want (someone else) to..."
(mote hoshii) "want you to bring me that"

but it is often more polite and proper to just say "please" (-te kudasai)

If you are asking if they want to do something, you can use -tai
(ikitai desu ka?) do you want to go?
