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”.

A word in The Etymologies of the 1930s appearing beside N. mîw “small, tiny, frail” under the root ᴹ√MIW (EtyAC/MIW²). The language is not marked, but it is probably Quenya with a meaning similar to its Noldorin equivalent.
