おむつ

おむつ
noun
diaper; nappy
1. diaper; nappy
An absorbent garment worn by babies or those who are incontinent. Originally from むつき (swaddling cloth) with the honorific prefix お. Both disposable (紙おむつ) and cloth (布おむつ) types exist.
おむつを()える時間(じかん)だ。
It's time to change the diaper.
(あか)ちゃんが()いているのは、おむつが()れているからだろう。

USAGE:
おむつ is the standard everyday word for diapers. The お prefix is not felt as honorific in modern usage — it is simply part of the word.

  • おむつを()える (change a diaper)
  • おむつを(はず)す (stop using diapers; begin potty training)
  • (かみ)おむつ (disposable diaper)
  • (ぬの)おむつ (cloth diaper)
