tittle

From Middle English tytle, titel, titele, from Anglo-Norman titil, titule and Medieval Latin titulus (“small stroke, diacritical mark, accent”), from Latin titulus (“title”). Doublet of tilde, titer/titre, title, titlo, and titulus.

From Middle English titillen, tytyllen, perhaps variants of Middle English tutelen (“to whisper, chatter”), from tutel (“mouth”), from Old English tūtel, tȳtel, related to Old Frisian tūte (“mouth”). Compare Middle English touten (“to jut out, project, protrude”), Middle English toute (“projection, mound, hill”), Middle Dutch tûte (whence modern Dutch tuit (“spout, nozzle, nose, point, peak, summit”)), Old Norse túta (“a teat-like prominence”), Danish tude (“spout”).
