köken: Compare Faliscan 𐌕𐌉𐌕𐌏 (tito), Umbrian 𐌕𐌉𐌕𐌉𐌔 (titis), South Picene 𐌕𐌉𐌕𐌞𐌌 (titúm). The name was attributed to the Sabines by the ancient author Julius Paris, which may connect to the legendary Sabine king Titus Tatius. Foreign origin of the name is evidenced by its distribution; it appears frequently in inscriptions from former Umbrian and Paelignian territory.
köken: Short for Tiidrik, an old Estonian equivalent of Old High German Theodoric, cognate with German Dietrich and English Derek. * Less often shortened from Tiitus.
