Daughter
Young Woman
noun
The kanji and the word are exactly the same. That means they share meanings as well.
娘 primarily means daughter but can also refer to a young woman (often unmarried). This is because its original form is 産す女 (むすめ), or "a woman who gives birth." Over time, it came to represent both daughters and young women.
The reading is the same as what you learned with the kanji.
私には娘が三人います。
I have three daughters.
松本さんのとこの娘さん、今年大学生になるんだって！
I heard Matsumoto's daughter is going to be a university student this year!
こんな時間に若い娘さんたちだけで歩いてたら危ないよ？
It's dangerous for young women to be walking around at this time of night, you know?
「私の娘は人魚なんだ。」「ええっ、それってつまり、あんた魚と結婚したってことか？」
"My daughter is a mermaid." "Whoa! Does that mean you married a fish?"
