Questions & Answers about Kemur þú með mér?
Why does the sentence start with the verb Kemur?
To ask a yes/no question in Icelandic, you swap the subject and the verb. A normal statement is Þú kemur (You come), so the question becomes Kemur þú? (Do you come? / Are you coming?).
Why is it mér and not mig for "me"?
The word mér is the dative form of ég (I). The preposition með forces the pronoun that follows it into the dative case whenever it means "together with" (accompaniment).
Does Kemur þú mean "Do you come" or "Are you coming"?
It means both! Icelandic does not have a separate continuous tense like English does. The present tense kemur covers both "come" and "are coming" depending on what makes sense in context.
Will með always make the next word dative?
No, með is a preposition that can take either the dative or the accusative case! It takes the dative case when it means doing something alongside someone, like here. However, if it means carrying or bringing something, it takes the accusative case instead.
