A word for light as an ethereal substance (“✱photons”), the equivalent of Q. linquë though of different origin (NM/283); see the Quenya entry for further discussion. It appeared in the forms glae and glaegal, the former derived from the root √GLAY (perhaps a variant of √GAL “light”), and the latter probably √GLAY + √KAL.
Conceptual Development: A similar form ᴱN. glaiw “light” appeared in Early Noldorin Word-lists of the 1920s (PE13/144).
A word for “grass” reported by Lisa Star from notes associated with The Lord of the Rings appendices, in unpublished material from the Marquette collection (TT17/33). It may be derived from an elaboration of the root √LAY which had other-plant related derivatives.
