Mature \Ma*ture"\, a. [Compar. {Maturer}; superl. {Maturest}.]
   [L. maturus; prob. akin to E. matin.]
   1. Brought by natural process to completeness of growth and
      development; fitted by growth and development for any
      function, action, or state, appropriate to its kind;
      full-grown; ripe.

            Now is love mature in ear.            --Tennison.

            How shall I meet, or how accost, the sage, Unskilled
            in speech, nor yet mature of age ?    --Pope.

   2. Completely worked out; fully digested or prepared; ready
      for action; made ready for destined application or use;
      perfected; as, a mature plan.

            This lies glowing, . . . and is almost mature for
            the violent breaking out.             --Shak.

      man of mature years.

   4. Come to, or in a state of, completed suppuration.

   Usage: {Mature}, {Ripe}. Both words describe fullness of
          growth. Mature brings to view the progressiveness of
          the process; ripe indicates the result. We speak of a
          thing as mature when thinking of the successive stayes
          through which it has passed; as ripe, when our
          attention is directed merely to its state. A mature
          judgment; mature consideration; ripe fruit; a ripe
          scholar.

Mature \Ma*ture"\, v. t. [imp. & p. p. {Matured}; p. pr. & vb.
   n. {Maturing}.] [See {Maturate}, {Mature}.]
   To bring or hasten to maturity; to promote ripeness in; to
   ripen; to complete; as, to mature one's plans. --Bacon.

Mature \Ma*ture"\, v. i.
   1. To advance toward maturity; to become ripe; as, wine
      matures by age; the judgment matures by age and
      experience.

   2. Hence, to become due, as a note.
