Questions & Answers about Ég klippi pappírinn áður en ég festi hann með límbandi.
The ending -inn is the definite article in Icelandic, attached to the noun itself.
- pappír = paper
- pappírinn = the paper
Unlike English, Icelandic usually adds the onto the end of the noun instead of writing it as a separate word.
Because klippa is the infinitive form, meaning to cut, while klippi is the form used with ég (I) in the present tense.
So:
- að klippa = to cut
- ég klippi = I cut / I am cutting
This is a very common pattern in Icelandic verbs:
- að festa → ég festi
- að tala → ég tala
Some verbs change more than others, but here klippa → klippi is just the normal 1st person singular present form.
