áállum

Ollum is a grammatical form in Icelandic, serving as the dative plural of the adjective allur and of the pronoun allir meaning “all” or “everyone.” In use, it marks the indirect object or beneficiary of an action, indicating to whom something is directed or who is affected.

In Icelandic, adjectives and pronouns decline for gender, number, and case. The form ollum appears specifically in the dative plural, where it functions as the recipient or beneficiary in a sentence. It is commonly found with verbs that take a dative object or with verbs that govern indirect objects, and it can appear in both spoken and written Icelandic.

Etymology and relation to related forms: ollum derives from the Old Norse/Proto-Norse base for “all.” The word is related to the common Nordic root that appears in related languages, and it has cognates in other Scandinavian languages, though the exact spelling and usage reflect Icelandic grammar and orthography. The base form allur (meaning “all” or “every”) manifests as different inflected forms across cases and numbers; ollum is the standard dative plural.

Usage notes: ollum is a functional word rather than a content word, used to indicate recipients or beneficiaries in sentences. It is not a proper noun and should be written in lowercase when appearing mid-sentence. A typical example is: “Ég sagði það öllum.” meaning “I told that to everyone.”
