Questions & Answers about Ef ég fæ skilaboðin í dag, þá svara ég strax.
Ef means if.
Here it introduces the condition:
Ef ég fæ skilaboðin í dag = If I get the message today
So the sentence has two parts:
- the if-clause: Ef ég fæ skilaboðin í dag
- the main/result clause: þá svara ég strax
This is a very common Icelandic pattern for conditional sentences.
Fæ is the 1st person singular present tense form of the verb fá = to get / to receive.
So:
- ég fæ = I get
- þú færð = you get
- hann/hún/það fær = he/she/it gets
It is an irregular verb, so the form does not look exactly like the infinitive fá.
In this sentence, ég fæ means I get / I receive.
