light's polite compromise — it passes through but refuses to tell you what's behind

means Allowing light to pass through but not in a way that lets you see clear shapes on the other side — frosted glass rather than a window.

from From Latin 'translucens,' the present participle of 'translucere,' meaning 'to shine through' — built from 'trans-' (across, through) and 'lucere' (to shine), itself rooted in 'lux,' light. So the word is literally light traveling across: the same 'luc-' that glows in 'lucid' and 'illuminate.' It entered English by the 16th–17th century, originally describing things that transmit light.
