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!

verb. to err

aiane

pronoun. anybody (thing, one) else; someone else, another

The correlative combinations ᴹQ. aiane or aine “anybody (thing, one) else; someone else, another” appeared Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/103 and note #42), both proniminal forms of ᴹQ. aia- “other”. These replaced various rejected forms: {arane, are} >> {warane, ware} >> {astane, asse, anasse} >> aiane, aine.

Neo-Quenya: For purposes of Neo-Quenya I would use ᴺQ. hyaquen for “someone else, another”, Q. hya “other” and quén “person”.

verb. to err
