Questions & Answers about Notandinn kvartar yfir því að þurfa að uppfæra forritið.
Why do we need því here? Couldn't we just say "kvartar yfir að"?
In Icelandic, a preposition like yfir usually cannot connect directly to an að clause or an infinitive verb. It needs a "dummy" pronoun to attach to. We use the pronoun það, which changes to því here because the preposition yfir governs the dative case when used with kvarta.
Why are there two aðs in a row with að þurfa að uppfæra?
English uses an -ing form here ("about having to update"), but Icelandic uses infinitives. The prepositional phrase yfir því triggers the first infinitive: að þurfa (to need). Then, because the verb þurfa always requires að before the next verb, we get the second one: að uppfæra (to update).
Does kvarta always take the preposition yfir?
Yes, when you are complaining about something, the fixed phrase is kvarta yfir (+ dative). It is best to memorize the verb, its preposition, and the case it rules together as a single chunk.
