ワンピース
wanpīsu[β̞ã̠mpʲiːsɨ]
The English phrase 'one piece' can be translated into Japanese as ワンピース (wanpīsu).
In Japanese, ワンピース (wanpīsu) has two primary uses. It refers to the popular manga and anime series 'One Piece', and it also refers to a one-piece dress in a fashion context. Note that while 'one piece' in English can refer to various single-garment items like swimsuits, in a Japanese fashion context, ワンピース specifically refers to a dress.
What does it mean word for word?
The word ワンピース is a loanword from English written in Katakana. It consists of wan (one) and pīsu (piece).
Which one should you use?
ワンピース is the standard term used for both the clothing item and the media series. In informal settings, you may also see the English initials 'OP' used to represent 'One Piece'.
How do you pronounce it?
wanpīsu
Did you know?
- In Japanese fashion magazines, you will often see the term ワンピ (wanpi) as a cute or trendy abbreviation of ワンピース.
- While ワンピース means a dress, a one-piece swimsuit is usually called a スクール水着 (sukūru mizu-gi) if it is the standard school type or ワンピース水着 to avoid confusion.
- If you use the word 'one' (一つ, hitotsu) and 'piece' (枚, mai) separately to describe a dress, a Japanese speaker might be confused by your intent.
