Onna (女) means "woman" or "female." It refers to an adult female person. Similar to "otoko," this word is used to describe gender, differentiate between males and females, or to form compound words like "onnanoko" (girl), indicating the female sex. Example: 彼女は女の医者です。(Kanojo wa onna no isha desu.) = She is a female doctor.

成人の女性を指す言葉です。性別を区別する時に使います。例：彼女は女の医者です。
