Questions & Answers about Barnen läser sina böcker.
Barn means child/children in an indefinite sense:
- ett barn = a child
- barn = children (some children, children in general)
Swedish usually marks definiteness by adding an ending to the noun.
Barnen is the definite plural form:
- barnen = the children
So Barnen läser sina böcker means The children are reading their books, not just Children are reading their books in a general sense.
Swedish often attaches the definite article to the end of the noun instead of using a separate word, especially when there is no adjective in front:
- en bok = a book
- boken = the book
- barn = children
- barnen = the children
So the -en in barnen works like the in English.
If there were an adjective, then Swedish could use both a separate article and an ending, e.g.:
- de små barnen = the small children
- de = the (plural)
- små = small
- barnen = the children
