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!
A word appearing as ᴱQ. malikon (malikond-) “amber” in the Qenya Lexicon and Poetic and Mythological Words of Eldarissa of the 1910s based on the early root ᴱ√MALA “yellow” (QL/58; PME/58). Its second element is probably ᴱQ. on(d) “stone” (QL/70). It also had an adjectival form ᴱQ. malikondea “of amber”.
Neo-Quenya: In Tolkien’s later writings, the root √MAL was tied to “gold”, but I think it could still be the basis for ᴺQ. malicon “amber” and ᴺQ. malicondëa “of amber”.
