Questions & Answers about На берегу дочка нашла большую ракушку и начала строить песочный замок с маленьким ведёрком.
Because берег has a special location form after на and в: на берегу = on the shore.
This is often called the locative or second prepositional. A small group of masculine nouns uses -у / -ю in fixed expressions of location:
- на берегу = on the shore
- в лесу = in the forest
- в саду = in the garden
But in other prepositional uses you may get the regular form:
- о береге = about the shore
So here на берегу is the normal idiomatic form.
Дочка is a more affectionate, everyday word than дочь.
- дочь = daughter, neutral or more formal
- дочка = daughter / little daughter, warmer and more conversational
Russian often uses diminutive-like forms for family members and children, even when English would just say daughter.
So дочка does not always have to mean a very small child; it often just sounds more natural and affectionate.
