Questions & Answers about Wir haben uns nicht ausruhen können, denn wir haben stattdessen die Hausarbeit abschließen müssen.
Why does this sentence use können and müssen instead of their past participle forms like gekonnt and gemusst?
This is the double infinitive rule. When a modal verb (like können or müssen) is used alongside another verb in the Perfekt (past) tense, we don't use its normal past participle. Instead, we use its infinitive form. So, rather than saying haben ... ausruhen gekonnt, German requires haben ... ausruhen können.
In both halves of the sentence, why does haben come so early instead of going to the end?
In a standard main clause, the conjugated verb (here, the helping verb haben) always takes the second position. The heavy lifting is done at the end of the clause, where both infinitives (ausruhen können and abschließen müssen) stack up together.
Why is the word uns in the first clause?
The German verb for "to rest" is sich ausruhen, which is a reflexive verb. Because the subject is wir (we), the reflexive pronoun must match it as uns (ourselves). A literal translation would be "We have not been able to rest ourselves".
Both ausruhen and abschließen are separable verbs. Why aren't their prefixes separated here?
Separable verbs only split when they are the conjugated verb in the sentence (for example, in the present tense: Wir ruhen uns aus). Because they are used in their infinitive forms here as part of the double infinitive structure, their prefixes stay firmly attached.
