Would it be proper to write "doorlight" without a space? If so, how is it different from "door light" in terms of its definition and usage?
I've mostly seen "doorlight" written to describe light coming through a doorway. I want to spark the mental image of that type of light when someone sees the word(s). Visually, I find doorlight more appealing but I don't think it's correct.
There is no entry for "doorlight" in any of the dictionaries indexed by OneLook Dictionary search.
