elf

(pl. edhil). Coll. pl. Edhelrim (or Edhellim) (UT:318). Also †eledh, pl. elidh, coll. pl. eledhrim (Letters:281), also elen, pl. elin, also with coll. pl. eledhrim (elen + rim with the regular change nr > dhr). (WJ:363, 377-78; the shorter coll. pl. Eldrim > *Elrim*** may also occur). But since elin** also means "stars", other terms for "Elf" may be preferred.
