Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!

Qenya 

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.

(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]”.
