Chinese : confusion with the use of 要，喜欢 (喜歡)，想 and 会(會)
I'm confused on how to say "I want..." and "I like..." in Chinese. Sometimes, I see the translation as 要 and other times as 喜欢, and some other times as 想. How do I determine which word to use?
Also, I sometimes see 要 used as "going to..." or "will..." and other times it's 会. How do I determine which word to use?
By the way, I'm trying to learn simplified Chinese (Mandarin) and traditional Chinese at the same time, so could that be the source of confusion? Thanks!
