A noun for “foot” derived from the ᴹ√TAL (Ety/TAL). It is unusual in that its plural form tel involved Ilkorin i-affection but not the suffix -in, as noted by Helge Fauskanger (AL-Ilkorin/tal).

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 [[ilk|[ls] became [ll]]], though this is the only example of this change.
