Questions & Answers about Ég man ekki lykilorðið, en ég hef allavega notendanafnið.

Why is man used here, and what is the infinitive?

Man is the 1st person singular present tense of the verb muna (to remember).
So Ég man = I remember / I do remember (and with ekki, it becomes I don’t remember).

Why does Icelandic say Ég man ekki ... instead of putting the negation before the verb like English?

In Icelandic, the negation ekki typically comes after the finite verb (the conjugated verb) and often before the main object/complements.
So the normal pattern is:

• Ég man ekki X.
• Ég hef ekki X.

You can sometimes move things around for emphasis, but this is the default, neutral placement.

What case are lykilorðið and notendanafnið, and how can I tell?

Both are accusative singular with the definite ending. These verbs take a direct object:

• muna (remember something) → object in accusative
• hafa (have something) → object in accusative

You can tell they’re definite because of the attached -ið ending (see next question).

Why do the nouns end in -ið? Is that “the”?
