lempë cardinal "five" (LEP/LEPEN/LEPEK, GL:53, VT42:24, VT47:10, 24); lempëa ordinal "fifth", an analogical formation replacing older lemenya, in turn altered from the historically "correct" form lepenya because of analogy with the cardinal lempë "five" (VT42:25; Vanyarin Quenya maintained lepenya, VT42:26)
lempë
cardinal. five
The Quenya word for “five” derived from the root √LEPEN via the Quenya syncope and metathesis: ✶lepene > lepne > lenpe > lempe (PE17/95; VT42/24; VT47/10; VT48/6; Ety/LEP).
Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. lemin “five” under the early root ᴱ√LEH [LEǶE] “half”, and Q. lempe was “ten” in this 1910s document (QL/52). In the contemporaneous Gnomish Lexicon, the word lempe was “five” (GL/53). In the Early Qenya Grammar of the 1920s (EQG), lemin “five” reappeared and ᴱQ. lempe was “half” (PE14/49, 82, 84). Beginning with The Etymologies of the 1930s the usual Quenya word for “five” was lempe (Ety/LEP), but occasional variants like lemne and lemen continued to appear (PE17/95; VT48/6).

per-
prefix. half-, half-, [ᴹQ.] semi-
A prefix for “half-” implied by names like Pereldar “Half-elven” (Let/386), clearly based on the root √PER of the same meaning (PE17/173). It may also mean “semi-” as in ᴹQ. Perómandar “semivocalic” (PE18/30).
pereldar
collective name. Half-elven
The Quenya term for those with mixed Mannish and Elvish blood such as Elrond and Elros (Let/386, PM/348), though in The Lord of the Rings itself, only its Sindarin equivalent Peredhil was used (LotR/1034). Pereldar is a compound of the prefix per- “half-” and the plural of Elda “Elf”.
Conceptual Development: The term ᴹQ. Pereldar appeared in The Etymologies, but there it was translated “Half-eldar” and referred to those Elves such as the Danians who turned back on the journey to Valinor (Ety/PER, LR/215). Pereldar was first applied to the Half-elves in the draft of The Lord of the Rings (RS/412). In later writings, the term for the Elves who did not go to Aman was Q. Úmanyar.

peresta
fraction. one half
