Questions & Answers about Jag borstar tänderna två gånger om dagen.
Why do we use om dagen here instead of i dagen?
When talking about how often something happens, Swedish splits time words into two groups. We use om with days (om dagen) and years (om året). We use i with weeks (i veckan) and months (i månaden).
Why does the sentence use tänderna (the teeth) instead of mina tänder (my teeth)?
In Swedish, you usually do not use possessive words like my or your with body parts if it is obvious who they belong to. Instead, you use the definite form. Since you are the one brushing, Swedish just says tänderna (the teeth).
Is dagen in the definite form here?
Yes! When expressing frequency like this, Swedish always uses the definite form of the time word. So it is always om dagen, never om en dag.
How would I say once a day instead of twice?
The singular of gånger is en gång. To say once a day, you would say en gång om dagen.
