Questions & Answers about Ég set servíettur á borðið áður en gestirnir koma.
Set is the 1st person singular present tense form of the verb að setja meaning to put / to place / to set.
So:
- að setja = the infinitive, to put
- ég set = I put / I am putting
This is similar to English to come vs I come.
Ég means I and it is the subject of the sentence.
Icelandic usually states the subject explicitly, just like English does in normal sentences. So:
- Ég set ... = I put ...
You normally cannot just leave out ég the way you can in some languages.
