sirpë

stem, stalk

sirpë noun "stem, stalk" (QL:84)

telco

stem

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)

sirpë

noun. stalk, slender tube, stem
