Questions & Answers about Ef þú ferð héðan núna, nærðu líklega lestinni.
This is very normal in Icelandic.
In sentences like this, Icelandic often uses the present tense to talk about a future result:
- Ef þú ferð héðan núna = If you leave here now
- nærðu líklega lestinni = you will probably catch the train
So even though English often uses will in the main clause, Icelandic usually does not need a separate future tense here. The present tense is enough when the future meaning is clear from context.
Ef means if.
It introduces a conditional clause, just like in English:
- Ef þú kemur = If you come
- Ef það rignir = If it rains
In your sentence:
- Ef þú ferð héðan núna = If you leave here now
So everything after ef sets up the condition for what happens in the main clause.
