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,
