Questions & Answers about Ég set símann á náttborðið og fer í inniskóna.
Because símann is the accusative singular definite form of sími.
Here, símann is the direct object of set: you are putting the phone somewhere.
A quick breakdown:
- sími = a phone, phone
- síma = a phone/phone in the accusative singular
- símann = the phone in the accusative singular
So after ég set you need the object form, not the basic dictionary form.
Because Icelandic usually uses:
- accusative after á when something is moving onto a place
- dative after á when something is already on a place
In this sentence, the phone is being moved onto the nightstand, so you get:
- á náttborðið = onto the nightstand
Compare:
- Ég set símann á náttborðið. = I put the phone onto the nightstand.
- Síminn er á náttborðinu. = The phone is on the nightstand.
So this is a very common Icelandic pattern: motion = accusative, location = dative with certain prepositions.
