I'm writing a sentence where pale gray morning light is being viewed through window blinds. I'm trying to think of a way to describe its entrance without sounding cliché. What are some good verbs to use for how light moves?
permeate might fit.
v. ~ to pass into or through every part of: sunshine permeating the room
Example: The morning light permeated the room through the window blinds.
The word glint is is nice and pithy. Light also could gleam or glare, sparkle, glimmer, or shimmer.
Morning light spilled has 2,010 results in Google books. Morning light filtered earns a respectable 13,200 results, whereas morning light slipped gains only 264 results. If the OP is looking for an expression which is not clichéd, slipped is a worthy candidate.
To a physicist, light moves either as a particle or as a wave; but that doesn't really help you much unless you want to use some aquatic metaphor.
You could go all-out with metaphor like Homer with "Dawn's rosy fingers", but maybe that sort of thing is cliché.
