娘
"Daughter."
Here, '娘' refers to the speaker's own daughter in a familial context, denoting the female offspring of the individual.

My daughter is a university student.
In this sentence, '娘さん' refers respectfully to someone else's daughter, showing courtesy and politeness in addressing individuals outside one's own immediate family.
昨日、隣の娘さんが手伝ってくれました。

Here, '娘' is used to denote a general young woman or girl, not specifically in the sense of familial connection, often contextually referring to youth and innocence.
