Questions & Answers about Hann kemur á þriðjudaginn.
Why does á take the accusative word þriðjudaginn here instead of the dative?
When talking about days of the week, using á + the accusative case + the attached definite article (the -inn at the end) means "this coming [day]". So, á þriðjudaginn means he is coming on this upcoming Tuesday. If we used the dative case without an article (á þriðjudegi), it would change the meaning to a recurring event: "on Tuesdays" in general.
Why is there an attached "the" (-inn) at the end of þriðjudaginn if the English translation is just "on Tuesday"?
While English just says "on Tuesday" to mean the upcoming one, Icelandic requires the definite article to lock in that specific day. You are literally saying "on the Tuesday". Without it, the sentence wouldn't make sense as a specific future plan.
The word kemur means "comes". Why is it translated as "is coming"?
Icelandic doesn't have an exact match for the English "is doing" (continuous) tense for most everyday actions. The simple present tense kemur covers both "comes" and "is coming". Furthermore, just like in English, Icelandic frequently uses the present tense to talk about a scheduled event in the future.
