  • (v. t.) To show, or make evident, by reasoning or proof; to prove by deduction; to establish so as to exclude the possibility of doubt or denial.
  • (v. t.) To exhibit and explain (a dissection or other anatomical preparation).

Definition:

  • (p. p.) of See
  • () p. p. of See.
  • (a.) Versed; skilled; accomplished.

Example Sentences:
