Questions & Answers about Kennarinn fær sér kaffi úti.
Why do we use sér instead of sig here?
Does sér mean "himself" or "herself" in this sentence?
Can I just say "Kennarinn fær kaffi" without sér?
You could, but it sounds a bit different. The verb að fá on its own simply means "to receive" or "to get." Adding the reflexive pronoun to make að fá sér is a very common everyday idiom that specifically means "having" or "getting oneself" something to eat or drink.
I remember that kennari means "teacher." Why does it end in -nn here?
This is a quick reminder about how "the" works in Icelandic. The definite article (the word for "the") is usually attached to the end of the noun instead of being a separate word. So, kennari (a teacher) becomes kennarinn (the teacher).
