Questions & Answers about Ef þú stígur á gildruna, þá missir þú lífspunktinn.
Why is the word order missir þú instead of þú missir in the second half of the sentence?
This is because of the resumptive adverb þá. In Icelandic, the V2 (verb-second) rule dictates that the main verb must be the second grammatical element in a main clause. Since þá occupies the first slot of the main clause, the verb missir must come immediately after it, causing the subject þú to invert.
Could I drop the word þá and still have a correct sentence?
Yes, you can omit þá, but it is extremely common and natural in Icelandic to use it to anchor the main clause after an ef (if) or þegar (when) clause. If you do drop it, the main clause still starts with the verb (missir þú) because the entire conditional clause acts as the first position. Including þá makes the transition feel smoother and emphasizes the cause-and-effect relationship.
Why does the preposition á trigger the accusative case for gildruna here instead of the dative?
The preposition á takes the accusative case when it describes motion or an action directed onto a destination. Because you are actively stepping onto the trap, it takes the accusative. If the sentence were about a stationary state, like standing still on top of the trap, you would use the dative case (á gildrunni).
