hæfum

höfum is the first-person plural present indicative form of the Icelandic verb hafa, meaning to have. It is used to express possession when the subject is "we" (við). Höfum is also the standard auxiliary verb in Icelandic for forming perfect tenses, combined with a past participle, as in Við höfum unnið verkefnið (we have completed the project) or Við höfum fengið boð (we have received a message).

In addition to its function as an auxiliary, hafa can occur as a main verb to denote possession in the present tense with forms such as við höfum bíl (we have a car). The full present-conjugation set includes ég hef, þú hefur, hann hefur, við höfum, þið hafið, þau hafa, reflecting its irregular yet highly productive role in Icelandic grammar.

Etymology and related forms: hafa derives from Old Norse hafa and is cognate with related Germanic forms in other languages, including the English have. The Icelandic form höfum is the contemporary plural present form, while other persons use slightly different endings, as seen in hafið (you have) and hafa (they have).

Common usage notes: höfum frequently appears in written and spoken Icelandic, especially in contexts that describe completed or ongoing actions up to the present moment. It is a versatile component of verb construction in the language, essential for expressing both possession and perfect aspect.
