Bílum

Bílum is the dative plural form of bíll, the Icelandic noun meaning "car" or "vehicle." In Icelandic, nouns are declined for case and number, so bíll has a dative plural form used when referring to multiple cars in contexts that require the dative case.

As a grammatical form, bílum functions to mark a noun as being in the dative case in plural. It does not convey a separate lexical meaning beyond indicating that the cars are the indirect object, are related to a preposition that governs the dative, or are associated with verbs that require the dative. The form appears in written and spoken Icelandic where the dative is appropriate; in other contexts, the nominative bílar or the genitive bíla would be used.

Bílum is therefore primarily of interest to students and scholars of Icelandic grammar and to readers seeking to parse sentences involving multiple cars or verbs and prepositions that require the dative. It serves as an example of how Icelandic marks grammatical relationships through case inflection rather than relying solely on word order.
