Ilk. tell n. “close, end, last part” (Category: End (n, temporal))
A noun meaning “close, end, last part” derived from the root ᴹ√TELES (EtyAC/TELES). Its Quenya cognates ᴹQ. telle and ᴹQ. tella (< ᴹ✶télesā) suggest a primitive form of *✶telesē. The middle [e] would have vanished due to the Ilkorin syncope, after which apparently the [ls] became [ll], though this is the only example of this change.
