daughter (of someone of high standing)
Formal term for one's own daughter, typically used when referring to the daughter of a person of high social status or in very polite contexts.
I hear the company president's daughter is getting married next month.
Honorific term used to refer to someone else's daughter, often with the prefix ご (ご息女).
How old is your daughter?
息子 (son) and 息女 (daughter) share the kanji 息 and are easily mixed up despite referring to opposite-gender children.
Compound of 息 (そく, 'son' or 'child') and 女 (じょ, 'woman' or 'daughter'). The combination specifically denotes a daughter, with a formal and respectful nuance.
