In a previous post I have emphasized that the present tense in Norwegian is quite easy for regular verbs. To create the present tense you only add "-r" to the infinitive form, and the conjugation of the verb doesn't change based on who does the action. Example, Jeg spiser (I eat) han spiser (he eats).
Unfortunately not all verbs are regular and some of the verbs are impossible to avoid. Some very important irregular verbs are:
Å være (to be) - Er (present tense) - Var (past tense)
Å gjøre (to do) - gjør (present tense) - gjorde (past tense)
Å vite (to know) - vet (present tense) - visste (past tense)
In addition there are the "modalverbs", verbs that usually has an additional verb in the infinitive form. Example, jeg skal spise. "Skal" is the infinitive form of "skulle". However, these are the topic of another post.
