About なおす

(なお) is a verb that means 'to fix', or 'to redo'. It is used when saying that something needs to be done a second time (usually due to the result/quality being insufficient the first time). To use (なお), it will need to be attached to the ます stem form of any verb.
  • (かみ)ちゃんと()まってなかったので()(なお)ます
    Because my hair isn't properly dyed, I will redo it.
  • フェンス()なおす
    To repaint the fence.
With する verbs, the conjugation rules are slightly different. する will become し, and then (なお) will be connected in the regular fashion. In some situations, する may be replaced with やる (a very casual equivalent of する). As やる is a う-Verb, it will be conjugated as やり(なお).
  • 客様(きゃくさま)挨拶(あいさつ)(なお)
    To re-greet the customer.
  • プロポーズやり(なお)(こと)出来(でき)ないから緊張(きんちょう)ている
    Because you can't redo proposals, I am nervous.
(なお) (to fix) should not be confused with (なお)す (to heal/mend). The kanji (ちょく) literally means 'straight', or 'direct', and implies that one should 'straighten out' something.

    Hi, I don’t understand this example. I convinced myself that it was probably past form (ta) because of the 方がいい/ it would be better. But why is the non past form also correct. What is the difference?

  • Arwin1


    I was wondering the same thing.

    They may have made changes to the ほうがいい grammar point recently, now at the end of it it now mentions that the dictionary form can be used, but is understood as more of a general opinion rather than direct advice to the listener.

    I think in this case though, it sounds much more like direct advice than a general opinion, but maybe there’s more nuance to it than just that.
