root. *sponge, fungus
swanda
noun. sponge, fungus
A noun for “sponge, fungus” appearing as N. chwann or hwand in The Etymologies of the 1930s derived from primitive ᴹ✶swanda under the root ᴹ√SWAD (Ety/SWAD). In Noldorin of the 1930s, ancient initial sw became voiceless hw, and then this hw became chw.
Neo-Sindarin: Since the change of initial hw to chw did not occur in the Sindarin of 1950s and 60s, I would adopt this word as ᴺS. whand “sponge, fungus”.
