Questions & Answers about Hún undirbýr sig fyrir prófið í kvöld.
Because undirbúa sig means “to prepare oneself.” The reflexive sig refers back to the subject (hún). Without sig, undirbúa would need some other direct object (e.g., “prepare the test” = undirbúa prófið).
- Correct: Hún undirbýr sig … (She prepares herself …)
- Different meaning: Hún undirbýr prófið … (She prepares the test …, e.g., a teacher)
Hana is the non-reflexive 3rd-person feminine accusative pronoun and refers to another woman, not the subject. To refer back to the subject, Icelandic requires the reflexive set (sig/sér/sín). So:
- Hún undirbýr hana = She prepares her (someone else).
- Hún undirbýr sig = She prepares herself.
Sig is accusative. The reflexive pronouns (3rd person, all genders, singular and plural) are:
- Accusative: sig
- Dative: sér
- Genitive: sín
Which one you use depends on the verb or preposition’s case requirements. Here, undirbúa sig takes accusative.
