young wife
Refers to a wife who is young, often with a nuance of being recently married or youthful in appearance. Can carry a slightly literary or romantic tone.
彼は若妻と静かな郊外に住んでいる。
He lives in a quiet suburb with his young wife.
Compound of 若 (young) and 妻 (wife). The reading わかづま is a straightforward combination of the readings of the two kanji.
