From tri- + ūnus. The noun triūnitās is attested in some late antique and medieval Christian texts as an alteration of trīnitās, apparently for the sake of emphasizing the theological concept of the trinity being one god in three persons. Subsequently, the adjective form triūnus is mentioned alongside the noun triūnitās in a list of words derived from trēs in Derivationes, an etymological dictionary attributed to the grammarian Huguccio of Pisa (now thought to be a different person from the canonist named Huguccio).
