Questions & Answers about Ég ligg í rúminu og les tímaritið.
How does this sentence express "am lying ... and reading" without using the verb for "to be"?
To show an ongoing action, Icelandic often uses a posture verb (liggja, to lie; sitja, to sit; or standa, to stand) joined by og to another verb. Instead of using the "vera að" pattern to say you are doing something, it is much more natural to say ég ligg ... og les (I lie and read).
Why do we use the form les after og instead of the infinitive lesa?
In this posture-verb structure, both verbs must match the subject in tense and person. Since the first verb is ligg (I lie, first-person singular), the second verb must also be the first-person singular present tense form, which is les (I read).
Why is the word for bed rúminu here instead of rúmið?
The preposition í (in) takes the dative case when it describes a static location where no movement towards a new destination is happening. Since you are resting in one spot, the neuter word for bed with its attached "the" ending takes the dative definite form, rúminu.
What makes up the word tímaritið?
This neuter noun means "the magazine." It is a compound of tími (time) and rit (writing or publication). The -ið at the end is the attached definite article meaning "the". It is in the accusative case here because it is the direct object being read, which for neuter words looks exactly the same as the dictionary form.
