Questions & Answers about Vikan er liðin.
Broken down word by word:
vikan – the week
- vika = week
- -n is the definite article suffix (the) in Icelandic, so vikan = the week (subject, nominative case).
er – is
- Present tense, 3rd person singular of vera (to be), just like is in English.
liðin – passed / over / elapsed
- This is the feminine singular form of the past participle liðinn (from the verb líða = to pass, to elapse).
- Here it functions like an adjective: liðin = (has) passed, i.e. over.
So the literal structure is: The-week is passed, which corresponds to The week is over in natural English.
