Morphology

blackout = black (transparent) = out + black

The meaning 'no electrical power / lights off' follows directly from 'black' (dark) + 'out' (extinguished/off). [Postprocessing: moved 'out' from base_words to prefix]

Etymology

Blackout is made from black ('dark') and out ('off'), and people began to use it for times when the electricity went off and everything went dark. That is why a blackout now often means a power cut in an area.
