Höfðuð

Höfðuð is an Icelandic word. It is the past tense plural form of the verb "hafa," which means "to have." Therefore, "höfðuð" translates to "you (plural) had" or "they had" in English, depending on the context and whether the subject is second or third person plural.

In Icelandic grammar, verbs change their form based on tense, mood, person, and number. "Hafa" is a strong verb, meaning its past tense is formed through internal vowel changes rather than by adding a suffix. The present tense singular forms are ég hef (I have), þú hefur (you have, singular), hann/hún/það hefur (he/she/it has). The present tense plural forms are við höfum (we have), þið hafið (you have, plural), þeir/þær/þau hafa (they have).

The past tense conjugation of "hafa" is as follows: ég hafði (I had), þú hafðir (you had, singular), hann/hún/það hafði (he/she/it had). The plural past tense forms are við höfðum (we had), þið höfðuð (you had, plural), þeir/þær/þau höfðu (they had). Thus, "höfðuð" specifically refers to the second person plural past tense of "hafa," meaning "you (all) had." It can also be used as the third person plural past tense if the context implies it, though "höfðu" is the more common form for third person plural.
