Questions & Answers about Við þurfum rétta kóðann, annars opnast lásinn ekki.
Why does the verb opnast come right after annars?
Annars acts as an adverb here, taking up the first position in the second main clause. Because Icelandic strictly follows the V2 (verb-second) rule, the verb opnast must come immediately after it in the second slot. This pushes the subject lásinn to the third position.
Why does the verb opnast end in -st?
This is the middle voice form of the active verb opna (to open). You use opna when someone is opening something (like opening a door), but you use opnast when something opens by itself or changes state. Since the lock is doing the opening itself here, the middle voice is required.
Why is it rétta kóðann instead of the dictionary form réttur kóði?
The verb þurfa (to need) forces its object into the accusative case. Kóði is a masculine noun, so its definite accusative form is kóðann. The adjective réttur (right) must agree with it, taking the weak accusative form rétta because the noun has the definite article attached.
Why does ekki go at the very end of the sentence?
In an Icelandic main clause, the negation word ekki normally follows the finite verb and the subject. Because annars takes the first position, the verb opnast takes the second, and the subject lásinn takes the third, ekki naturally falls into the final spot of this clause.
