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).
