loa

growth

loa, noun literally "growth", used of a solar year (= coranar) when seasonal changes are considered (Appendix D; in PM:126 loa is translated "time of growth". Pl. loar, or "löar", in MR:426) The form loa is also mentioned as the hypothetical Quenya cognate of Sindarin lô ("swampy"), but precisely because it clashed with loa "year", this Quenya cognate was not in use (VT42:10)

olmië

noun. growth

A word for “growth” in various notes on Elvish maturation from 1959, an abstract noun based on √OL “grow” (NM/84, 119). More specifically, it referred to the early period or process of life where one was actively growing, as opposed to later life after one had reached maturity: coivië.

olaste

noun. growth

A noun appearing as ᴹQ. {alaste >>} olaste “growth” in the Quenya Verbal System (QVS) of 1948 as a combination of {ala- >>} ᴹQ. ola- “grow” with the general action suffix ᴹQ. -ste (PE22/110).

Neo-Quenya: Since Tolkien revised the general action suffix to -sta a few years later, I would update this noun to ᴺQ. olasta “growth” for purposes of Neo-Quenya. I would use this word for “growth” in general, both physical and metaphorical, as opposed to olmië as the period or process of life where one is growing.
