   av to satisfy one's self: cf. F. automne. See {Avarice}.]
   1. The third season of the year, or the season between summer
      and winter, often called "the {fall}." Astronomically, it
      begins in the northern temperate zone at the autumnal
      equinox, about September 23, and ends at the winter
      solstice, about December 23; but in popular language,
      autumn, in America, comprises September, October, and
      November.
      [1913 Webster]

   Note: In England, according to Johnson, autumn popularly
         comprises August, September, and October. In the
         southern hemisphere, the autumn corresponds to our
         spring.
         [1913 Webster]

   2. The harvest or fruits of autumn. --Milton.
