ᴹ√SKWAR root. “crooked”
This root appeared in The Etymologies of the 1930s as ᴹ√SKWAR “crooked” with derivatives like ᴹQ. hwarin “crooked” and Dan. swarn “perverse, obstinate, hard to deal with” (Ety/SKWAR). In red-ink revisions to the Outline of Phonology (OP2) from the 1950s Tolkien decided that the initial combination skw- was not possible (PE19/78 and note #51). For purposes of Neo-Eldarin, this root might be salvaged by assuming its actual form was ᴺ√SWAR.
