〜なさい — a direct command (parent/teacher tone)

JLPT N4 Verbs & Politeness

A firm instruction: 早く寝なさい — go to bed now

ます-stem + なさい gives a direct command — firmer than an invitation, but softer and less harsh than the plain imperative form. It's strongly associated with parents talking to children or teachers talking to students, and sounds odd or condescending between adult peers.

How to form it

PatternExample

Watch out

なさい carries a built-in parent-to-child or teacher-to-student tone — using it on a coworker or stranger, even politely intended, comes across as condescending rather than firm-but-fair.
