aðilunum

Aðilunum is the dative plural form of the Icelandic noun aðili, which means "party," "participant," or "person involved." The root aðili refers to a person or entity taking part in an action, agreement, or discussion. The term covers individuals as well as organizations and can denote someone who has a stake, responsibility, or role in a process. In everyday language it is used to describe anyone who is involved in a matter, not necessarily in a position of authority.

In formal contexts such as law, business, and administration, aðili typically denotes a party to a contract or agreement, a participant in negotiations, or a stakeholder in a decision. The plural aðilar refers to multiple such parties, while aðilunum is used when the sentence requires the dative plural, for example with verbs or prepositions that govern the dative case.

Translations include "party" or "participant." See also related terms such as samningur (contract) and deilur (disputes).
