senno m (plural senni)
Of Germanic origin (whence also Old French sen, san "mind, sense, direction", Occitan sen, Catalan seny, Spanish sien), from Frankish *sinn (“sense, mental faculty, way, direction”), from Proto-Germanic *sinnaz (“mind, meaning”), from Proto-Germanic *sinþaną (“to go, find one's way”), from Proto-Indo-European *sent- (“to go”). Akin to Old High German sinn "mind, sense, judgment", Old English sinnan "to mind, meditate on, consider", Old English sīþ "journey". More at sense, send.
