telco noun "stem" of a Tengwa symbol (Appendix E). The Etymologies gives telco ("k") pl. telqui ("q") "leg" (the pl. form is said to be analogical) (TÉLEK). It seems, then, that the word can refer to a "stem" or "leg" in general as well as the stem of a Tengwa. In the pre-classical Tengwar system presupposed in the Etymologies, telco is used to refer to a carrier symbol (VT46:18, 33)

A noun in The Etymologies of the 1930s glossed “stem” under the root ᴹ√TELEK “stalk, stem, leg” (Ety/TÉLEK). Its Quenya cognate Q. telco “stem, leg” continued to appear in Tolkien’s later writings (PE17/122; LotR/1118).
Neo-Sindarin: Conceivably this word might also mean “leg” like its Quenya cognate. Such a thing is indicated by the name Telchandir, the Sindarin/Noldorin equivalent of Q. Telcontar “Strider” (AotM/62). However, I recommend using this word only for its attested gloss “stem” and suggest ᴺS. teleg for “leg”; see that entry for details.
