  What it means

  “Which was to be proved.” The Polish equivalent of the Latin Q.E.D. (quod erat demonstrandum) — used at the end of a proof or argument to signal that the point has been made.

  Vocabulary

  • czego — which (genitive)
  • należało — it was necessary / it was to be (past)
  • dowieść — to prove

  Grammar note

  'Czego' is genitive, used as the object of 'dowieść' (which takes the genitive). 'Należało' is the impersonal past form of 'należeć'.

  Cultural context

  Used in mathematics, logic, and rhetoric. Also used humorously in everyday speech after making a point.
