ほうがいい
hou ga ii
By Nihongo PathUpdated
This form is also taught at JLPT N4, where it carries a different sense or register.
Meaning
"it would be better to ~ / you had better ~" (advice).
ほうがいい gives advice: "you had better / it would be better to". Positive advice uses the た-form: 早く寝たほうがいいです "You'd better go to bed early". Negative advice uses the ない-form: そんなに食べないほうがいいです "You'd better not eat that much". Even though the た-form looks like past tense, the advice is about now or the future.
Health advice, suggestions to friends (take an umbrella, study more), and gentle warnings. Softened with と思います.
Formation
V = verb, N = noun, A = adjective.
V-た + ほうがいいです ／ V-ない + ほうがいいです

JLPT N5 tips
On the exam
- Blank + ほうがいいです → た-form (or ない-form for negative advice). Dictionary form and ます are the usual distractors.
- Health words (熱, 風邪, 疲れた) and 傘 sentences are classic ほうがいい contexts.
