Questions & Answers about Hun sier æsj på grunn av lukten.
Yes. Æsj is a very common Norwegian interjection, used when something seems disgusting, gross, or unpleasant. It works a lot like yuck, ew, or ugh in English.
In this sentence, Hun sier æsj means that she reacts by saying æsj.
Sier means says, so the sentence describes what she actually says out loud.
- Hun sier æsj = she says yuck
- Hun tenker ... = she thinks ...
- Hun føler ... = she feels ...
Because æsj is something spoken as a reaction, sier is the natural choice here.
Because æsj is not a full clause. It is just an interjection.
You use at after sier when what follows is a full statement:
- Hun sier at hun er trøtt. = She says that she is tired.
But here, she is just saying a single reaction word:
- Hun sier æsj.
So at is not needed.
