Questions & Answers about Þú getur notað rafmagnið hér.

Why is the verb form notað used here instead of the infinitive nota?

Icelandic modal verbs (like getur, má, vil, þurfa) require the past participle of the main verb, not the bare infinitive. So nota (to use) becomes notað (used) after getur.
Example:
• Þú getur tekið bókina. (not taka)
• Hún má ekki truflað mig. (not trufla)

Why is rafmagnið used instead of rafmagn?

Icelandic marks the definite article as a suffix.
• rafmagn = “electricity” (indefinite)
• rafmagnið = “the electricity” (definite)
Here you’re talking about the power supply available here, so you add -ið for neuter singular definiteness.

Can I use má instead of getur here? What’s the nuance?

Yes.
• Þú mátt nota rafmagnið hér. – Emphasizes permission (“you may/are allowed to”).
• Þú getur notað rafmagnið hér. – Emphasizes ability/possibility (“you can/are able to”).
In everyday speech they often overlap when you’re simply granting someone the go-ahead.

Why is hér at the end, and can I move it?
