Verb [た-form] + ほうがいいPrimary
Verb [ない-form] + ほうがいい
This phrase gives advice. It means 'you should do this' or 'it is better to do this'. You use it to suggest a good idea.
風邪をひいたなら、早く寝たほうがいい。
If you've caught a cold, you should go to bed early.
そんなにたくさん食べないほうがいいですよ。
You know, it's better not to eat that much.
ああ、もっと早く家を出たほうがよかった。電車に乗り遅れた。
Ah, I should have left the house earlier. I missed the train.
この件は、部長に直接報告したほうがいいと思います。
Regarding this matter, I think it would be better to report directly to the department head.
その映画、面白いから見たほうがいいよ。
That movie is interesting, you should totally see it!
This phrase is like telling someone what to do. It can sound strong. You can add 'I think' or small words like 'yo' or 'ne' to make it softer. This makes it sound more like a friendly suggestion.
This is different from '〜たらどうか'. That is a soft suggestion. '〜ほうがいい' is stronger advice. It is also different from '〜べきだ'. '〜べきだ' means you really must do something. It is a duty. '〜ほうがいい' is just a good idea, not a duty.
Watch out: When you say someone should do something, use the past tense form of the verb. For example, say "tabeta hou ga ii" (ate it is better). Do not say "taberu hou ga ii" (eat it is better). But for negative advice, use the "nai" form.
Don't use this when you want to say "I should have done that." For example, "I should have studied more" is not said with this grammar.
