brownout singular

Morphology

brownout = brown (semi-transparent) = out + brown

The electrical sense is clearly a partial 'out' (dimming) indicated by 'brown', but the technical link to voltage drop is metaphorical rather than a direct literal composition. [Postprocessing: moved 'out' from base_words to prefix]

Etymology

In electricity, brownout keeps the same image: a partial fall in power that makes lights look brown or dim instead of going fully 'out'. So a brownout is a temporary drop in voltage that can make devices fail or lights flicker.
