noun. air (as a region), air (as a region), *lower sky; [G.] breeze

An abstract noun in The Etymologies of the 1930s glossed “air as a region” under the root ᴹ√WIL (Ety/WIL). In other words, you breath N. gwelw (ᴺS. gwelu) “air as a substance”, but birds fly through gwilith, basically making it the lower sky below the clouds.

Conceptual Development: In Gnomish Lexicon of the 1910s, G. gwilith was “a breeze” (GL/45).
