How to say "improve" in Japanese
- 持ち直すもちなおすgodan verb, intransitive verbImprove in the sense of rallying: a situation, trend or condition that had been slipping recovers and picks up, so using it implies a prior downturn that is now reversing.
- 開けるひらけるichidan verb, intransitive verbUsed when luck, prospects or the like improve: one's fortunes brighten and the future opens up, as when things finally start going someone's way.
- 磨くみがくgodan verb, transitive verbImprove here means deliberately bettering something, above all a skill: you refine, hone or polish an ability, so the improvement comes from your own effort rather than chance.
- 怠るおこたるgodan verb, intransitive verbA dated word for an illness improving — getting better, easing off. Because it is dated, this is seldom the word you want for 'improve'; recognize it rather than reach for it.
- 上向くうわむくgodan verb, intransitive verbImprove as an upward turn: a trend, situation or condition bends upward and rises, so improvement is pictured as movement from lower to higher.
