Questions & Answers about Hún sefur alltaf undir sama teppi.
Breaking it down:
- Hún – 3rd person singular feminine pronoun in the nominative case: she (or it, if referring to a feminine noun). It’s the subject.
- sefur – 3rd person singular present tense of the verb sofa (to sleep).
- alltaf – adverb meaning always; it modifies the verb sefur.
- undir – preposition meaning under, used with the dative case here.
- sama – the adjective sami (same), here in the dative singular neuter form, agreeing with teppi.
- teppi – neuter noun in the dative singular, meaning blanket.
So the core structure is: Subject (Hún) – Verb (sefur) – Adverb (alltaf) – Prepositional phrase (undir sama teppi).
sofa is the infinitive form: to sleep. In Icelandic, you have to conjugate it for person and number.
Present tense of sofa is:
- ég sef – I sleep
- þú sefur – you (sg) sleep
- hann / hún / það sefur – he / she / it sleeps
- við sofum – we sleep
- þið sofið – you (pl) sleep
- þeir / þær / þau sofa – they sleep
In your sentence, the subject is hún (she), so you need the 3rd person singular present form sefur. Using sofa here (Hún sofa alltaf…) would be ungrammatical.
