Rafrænum

Rafrænum is a grammatical form in Icelandic. It is the dative plural inflection of the adjective rafræn, which means digital or electronic. In Icelandic, adjectives agree with the noun they modify in gender, number and case, so rafræn takes different endings depending on how the noun is used. Rafrænum appears specifically when describing plural nouns in the dative case, a construction that occurs after certain prepositions or in certain syntactic positions.

The word rafræn itself is built from the stem raf- meaning electricity plus the descriptive suffix -ræn, yielding a term used broadly for things related to digital technology and electronics. The dative plural form rafrænum thus functions as a modifier in phrases such as rafrænum tækjum (to digital devices) or rafrænum aðferðum (digital methods).

Usage is common in contemporary Icelandic, especially in technical writing, education and media discussions about technology, computing and digital culture. Because Icelandic adjectives decline for case, number and gender, rafræn has several inflected forms; rafrænum specifically marks plural and dative, while other forms such as rafræn, rafrænt, or rafrænar appear in nominative or other cases.
