nil

noun. blue-bell, harebell

A word in the Declension of Nouns of the early 1930s translated as “harebell” (PE21/19) or “blue-bell” (PE21/26), which are different English names for the same kind of flower.

Conceptual Development: In the Qenya Lexicon and Poetic and Mythological Words of Eldarissa of the 1910s, ᴱQ. qille (qilli-) was “bluebell” based on the early root ᴱ√QILI having to do with colours (QL/77; PME/77). These documents also had a more elaborate form ᴱQ. {qillenen >>} qillinin (qillinind-) for “bluebell”, where the second element was probably ᴱQ. nin (nind-) “blue” (QL/66).

proper name. Moon

A name for the moon in linguistic notes from 1930s (PE21/38, 41), perhaps a derivative of the root ᴹ√NDŪ “go down”, though this root usually applied to the Sun. Its dual form Nunt referred to both the sun and moon (PE21/38).
