## Origin

From Middle English trouthe, from Old English trēowþ ("truth, faith, fidelity, loyalty, pledge"), from Proto-Germanic *triwwiþō ("promise, covenant"), tracing back to a Proto-Indo-European root meaning "firm, solid." It is essentially "true" plus an abstract noun suffix, and is related to Icelandic tryggð ("loyalty").
