A noun in The Etymologies of the 1930s given as N. celw “spring, source” derived from the root ᴹ√KEL “go, run (especially of water), flow away downhill” (Ety/KEL). A similar form G. celu appeared in Gnomish Lexicon of the 1910s beside variant celwin, but there it had the gloss “rill, stream, runlet” (GL/25).
Neo-Sindarin: If adapted to Neo-Sindarin, this word would be ᴺS. celu as suggested in HSD (HSD).
