Questions & Answers about Hún skráir sig með kennitölu og símanúmeri.

Why is it Hún skráir sig and not just Hún skráir?

Because skrá sig is the reflexive construction meaning “to sign up/register oneself.” Without sig, skrá means “to register (something/someone else).” So:

• Hún skráir sig = She registers herself (signs up).
• Hún skráir barnið = She registers the child. Dropping sig in your sentence would change the meaning or make it incomplete.

Why is it sig and not hana?

Sig is the 3rd‑person reflexive object pronoun; it refers back to the subject of the clause (here, hún). Hana means “her” (some other woman), not the subject herself.

• Hún skráir sig = She registers herself.
• Hún skráir hana = She registers her (another woman).

What case is sig in, and what happens in other persons?
