Early Quenya

tendl

noun. string

serma

noun. string, cord

A word appearing as ᴱQ. serma “string, cord” in the Qenya Lexicon of the 1910s under the early root ᴱ√SERE [ÞERE] “twine, tie, bind” (QL/83).

Neo-Quenya: In Tolkien’s later writings √THER meant “sew”, but I think ᴺQ. serma can be salvaged if its use is limited to a smaller “string”.
