  What it means

  Literally “electronic brain,” this phrase was coined in Polish in the mid-20th century as a calque of the English “electronic brain,” an early popular name for computers. It refers to a computer or, more loosely, any complex calculating machine. Today it is mostly used humorously or nostalgically, evoking the era when computers filled entire rooms and the idea of a thinking machine was still science fiction. Younger Poles sometimes use it jokingly to describe a person who calculates very quickly, or to mock an overcomplicated system.

  Vocabulary

  • mózg — brain
  • elektronowy — electronic (adjective, nominative masculine)
  • mózg elektronowy — electronic brain; computer (dated/humorous)

  Grammar note

  The phrase is a simple noun phrase: mózg (nominative masculine noun) modified by the adjective elektronowy, which agrees with it in gender, number, and case. It behaves as a regular masculine inanimate noun in all declensions — accusative mózg elektronowy, genitive mózgu elektronowego, etc.

  Cultural context

  The term was popularized in Poland in the 1950s–70s when mainframe computers first arrived in research institutes. It now carries a retro, slightly ironic flavor — using it unironically would mark you as very old-fashioned. The closest English equivalents are 'electronic brain' or 'thinking machine.'
