Questions & Answers about Það er tölvan sem er leitað að, til að skrásetja hana.
Why is the past participle leitað in the neuter form rather than agreeing with the feminine noun tölvan?
This is an impersonal passive construction. When a prepositional verb like leita að is made passive, the past participle freezes in the default neuter singular form (leitað) and the preposition is stranded. It does not change to agree with the noun.
Why is the preposition að left hanging by itself after leitað?
In Icelandic relative clauses, you cannot place a preposition directly before the relative pronoun sem. Because the active verb phrase is leita að, turning it into a sem clause forces the að to move to the end of that clause, leaving it stranded.
Why does the sentence use the accusative pronoun hana at the end when tölvan is in the nominative case at the beginning?
While tölvan is nominative because it follows the 'to be' verb in Það er (It is), the pronoun at the end must follow the rules of its own clause. The verb skrásetja requires its direct object to be in the accusative case, so the feminine pronoun becomes hana.
What role does til að play before the verb skrásetja?
The phrase til að followed by an infinitive verb translates to 'in order to'. Here it connects the main action to its purpose, meaning 'in order to register it'.
