lócë

A word for “bight, bend, curl of hair” in 1964 notes on Dalath Dirnen (DD), a derivative √LOK “bend” that was elsewhere the basis for “snake” words (PE17/160). According to Christopher Gilson, the gloss “curl of hair” might instead apply to the root.

angwa

root. snake

The root √ANGWA “snake” with variant √ANGU appeared in The Etymologies of the 1930s as the basis for the words ᴹQ. ango “snake” (Ety/ANGWA) and angulóke “dragon” (Ety/LOK). The Noldorin equivalent am- seems to have survived only as a prefix (Ety/ANGWA), and is a good example of how [[on|[ŋgw] > [mb]]] in that language. There are a variety of other words for “snake” in Tolkien’s later writings, so whether this root remained valid is unclear.
