Reciprocal


Definition:

  • (a.) Recurring in vicissitude; alternate.
  • (a.) Done by each to the other; interchanging or interchanged; given and received; due from each to each; mutual; as, reciprocal love; reciprocal duties.
  • (a.) Mutually interchangeable.
  • (a.) Reflexive; -- applied to pronouns and verbs, but sometimes limited to such pronouns as express mutual action.
  • (a.) Used to denote different kinds of mutual relation; often with reference to the substitution of reciprocals for given quantities. See the Phrases below.
  • (n.) That which is reciprocal to another thing.
  • (n.) The quotient arising from dividing unity by any quantity; thus, / is the reciprocal of 4; 1/(a +b) is the reciprocal of a + b. The reciprocal of a fraction is the fraction inverted, or the denominator divided by the numerator.

Example Sentences:
