vet, kjenner or kan?

English know has three Norwegian equivalents, and the choice depends on what you know.

• vet (vite): facts and information, usually followed by a question word or a clause: vet hvor, vet hva, vet om (whether), vet at. Jeg vet ikke hvor hun bor (I don't know where she lives).
• kjenner (kjenne): people and places you are familiar with. Kjenner du Ola? (Do you know Ola?)
• kan (kunne): something you have learned, such as a language, or a poem or phone number by heart (utenat). Hun kan fransk (She knows French).

Tip: a question word or at after the gap points to vet. A person or a town points to kjenner. A language or something learned utenat takes kan.
