There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

linin-

prefix. many

linya

noun. pool

A noun in The Etymologies of the 1930s glossed “pool” derived from the root ᴹ√LIN of the same meaning (Ety/LIN¹).

Conceptual Development: A similar word ᴹQ. linde “pool” appears in the Declension of Nouns from the early 1930s (PE21/10), but this word is probably best avoided, as it clashes with Q. lindë “singing, song” (PE17/80).

(li)lin(n)ome

adverb. *many places

A correlative combination appearing in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/112), a combination of ᴹQ. li(n)- “several, many” and ᴹQ. nome “place[s]”.

hrimo(n)nome

adverb. *many places

The correlative ᴹQ. hrimo(n)nome appeared in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/112), a combination of ᴹQ. hrim- “many” and ᴹQ. nome “place”.

Neo-Quenya: For purposes of Neo-Quenya I would adapt this to ᴺQ. rimonomë “many places” using rim- “many” to be more compatible with Tolkien’s later writings.

linde
