Limit

  • (v. t.) A determining feature; a distinguishing characteristic; a differentia.
  • (v. t.) A determinate quantity, to which a variable one continually approaches, and may differ from it by less than any given difference, but to which, under the law of variation, the variable can never become exactly equivalent.
