A root in The Etymologies of the 1930s glossed “give way, make room, permit, allow”, with the derivatives in both Quenya and Noldorin having mostly to do with permission (Ety/DAB).

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.

yen
root. year
A root in The Etymologies of the 1930s glossed “year” with derivatives like ᴹQ. yén/N. în “year” (Ety/YEN). Tolkien’s ongoing use of words like Q. yén and S. ínias “annals” indicate its ongoing validity (LotR/377; MR/200), but in Quenya at least the meaning shifted to that of an “Elvish long year”, equal to 144 solar years (LotR/1107; MR/471; NM/84).
yenrinde
noun. year
A root in The Etymologies of the 1930s glossed “affect, disturb, alter” with derivatives like N. presta- “to affect, trouble, disturb” and N. pesso “it affects, concerns” (Ety/PERES; EtyAC/PERES). It had a short form ᴹ√PER (EtyAC/PERES), but in a separate entry in The Etymologies ᴹ√PER was glossed “divide in middle, halve” (Ety/PER) which doesn’t seem to be related.
