Other forms: glades
A glade is a sunny open space among trees. A woodland glade, sunlight in the glade, a clearing or glade.
The light is the point of the word: a glade is bright where a clearing is merely open, and the two are not quite the same. Such gaps matter ecologically, because many woodland flowers and butterflies need the sun that reaches the floor there.

From Middle English glade, glode, glede (“a gleam of light, bright space, an open space; an open or cleared space in a forest; a bright patch of sky; a bright surface of snow or ice”), of unknown origin, perhaps from Old English glǣd, glād, related to Old English glæd (“shining, bright”), (compare Old Norse glaðr (“bright”)).
