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 

-(n)ikka

suffix. small

A suffix used in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 to form correlatives for smallness in quantity or amount, such as ᴹQ. manikka “how small, ✱how little” and ᴹQ. tanikka “✱that small, that little” (PE23/108). Tolkien specified that it was “only used in interrogatives and demonstratives”. It was probably related to diminutive ✶-i(n)ki and the root √-NIK “small”.

mitsa

adjective. small
