Questions & Answers about Barn äter ofta choklad på helgerna.
Why isn't there an article before choklad?
In Swedish, just like in English, you use the zero article (no article at all) when making general statements about mass nouns. Because choklad is an uncountable substance and this sentence talks about it in a general sense, it doesn't need an article.
Why is it just Barn instead of Barnen at the beginning of the sentence?
When talking about a whole group in a general sense, Swedish uses the indefinite plural, just like English does. Barn is an ett-word that looks the same in its singular and plural indefinite forms. If you said Barnen, it would mean a specific group of children rather than children in general.
Why is helgerna in the definite plural form if the English translation just says "on weekends"?
To express a habit that happens repeatedly on certain days or periods, Swedish uses the preposition på followed by the definite plural of the noun. So på helgerna (literally "on the weekends") is the standard way to express the habitual "on weekends".
Why does the adverb ofta come after the verb äter?
This is because of the Swedish V2 rule, which dictates that the verb must be the second main element in a standard main clause. Because the subject Barn is in position one, the verb äter must take position two. The sentence adverb ofta then slots in right after the verb.
