Etymology

It is inherited from Middle English demonstracioun, borrowed from Old French demonstration and directly from Latin dēmōnstrātiō, dēmōnstrātiōnem,[2][3][4] from dēmōnstrāre, to point out, indicate, figuratively to prove (see demonstrate),[2][5] from dē-, entirely, and mōnstrāre, to point out, show (compare monster),[2] which Etymonline traces to Proto-Indo-European *men-, to think.[2]

Earliest recorded meaning
