Questions & Answers about Han ligner på sin far.
In modern spoken Norwegian, ligner på (or likner på) is the most natural way to say “looks like / resembles”:
- Han ligner på sin far. – He looks like his father.
In more formal or traditional Bokmål, you can also use ligner without på:
- Han ligner sin far.
Both are correct. Many learners find ligner på easier to remember, because it behaves like a verb + preposition unit, similar to English “look like”.
Literally, på often corresponds to “on”, “in”, or “at”, but in this sentence it does not have a clear, separate meaning.
With ligner (likner) it is best to think of ligner på as a fixed combination meaning “to look like / to resemble”. The på is required by usage, not by a literal meaning.
