What's the difference between presume and prove?

Presume


Definition:

  • (v. t.) To assume or take beforehand; esp., to do or undertake without leave or authority previously obtained.
  • (v. t.) To take or suppose to be true, or entitled to belief, without examination or proof, or on the strength of probability; to take for granted; to infer; to suppose.
  • (v. i.) To suppose or assume something to be, or to be true, on grounds deemed valid, though not amounting to proof; to believe by anticipation; to infer; as, we may presume too far.
  • (v. i.) To venture, go, or act, by an assumption of leave or authority not granted; to go beyond what is warranted by the circumstances of the case; to venture beyond license; to take liberties; -- often with on or upon before the ground of confidence.

  • (19) Compared with Sheehan's series in England, it was found the incidence of post-partum hypopituitarism in Okayama was presumably less than in England.
  • (20) In addition, we have shown that long-lived, presumably non-senescent, strains do not arise by suppressor mutation, but lose senescence plasmid DNA by another mechanism.

Prove


Definition:

  • (v. t.) To try or to ascertain by an experiment, or by a test or standard; to test; as, to prove the strength of gunpowder or of ordnance; to prove the contents of a vessel by a standard measure.
  • (v. t.) To evince, establish, or ascertain, as truth, reality, or fact, by argument, testimony, or other evidence.
  • (v. t.) To ascertain or establish the genuineness or validity of; to verify; as, to prove a will.
  • (v. t.) To gain experience of the good or evil of; to know by trial; to experience; to suffer.
  • (v. t.) To test, evince, ascertain, or verify, as the correctness of any operation or result; thus, in subtraction, if the difference between two numbers, added to the lesser number, makes a sum equal to the greater, the correctness of the subtraction is proved.
  • (v. t.) To take a trial impression of; to take a proof of; as, to prove a page.
  • (v. i.) To make trial; to essay.
  • (v. i.) To be found by experience, trial, or result; to turn out to be; as, a medicine proves salutary; the report proves false.
  • (v. i.) To succeed; to turn out as expected.
