"gå" is the infinitive form of the word. The infinitive form of a verb can be considered the "base" form. In English, if we think of the action "to walk", "walk" is in the infinitive form. If we get rid of the "to" part, then we have what is referred to as the "bare infinitive" or "zero infinitive" - the base form of the verb all by itself.
å gå - to go / to walk - infinitive form går - goes / is going / walks / is walking - present tense gikk - went / walked - past tense har gått - has gone / has walked - present perfect tense
