Questions & Answers about Bussen nærmer seg stasjonen.
nærmer seg is the present tense of the pronominal (reflexive) verb å nærme seg, which means “to approach.” The reflexive pronoun seg is mandatory here – it’s part of the verb. You cannot drop seg, nor does nærmer by itself carry the meaning “approach.” The structure is:
Subject + verb (nærmer) + reflexive pronoun (seg) + thing approached.
With nærme seg, Norwegian directly attaches the object you’re approaching without a preposition. So you say nærmer seg stasjonen, not nærmer seg til stasjonen. If you really want a “to-station” idea you’d switch verbs:
Bussen er på vei til stasjonen – “The bus is on its way to the station.”
