Embryo \Em"bry*o\, n.; pl. {Embryos}. [F. embryon, Gr.
   'e`mbryon, perh. fr. ? in (akin to L. ? E. in) + ? to be full
   of, swell with; perh. akin to E. brew.] (Biol.)
   The first rudiments of an organism, whether animal or plant;
   as:
   (a) The young of an animal in the womb, or more specifically,
       before its parts are developed and it becomes a fetus
       (see {Fetus}).
   (b) The germ of the plant, which is inclosed in the seed and
       which is developed by germination.

   {In embryo}, in an incipient or undeveloped state; in
      conception, but not yet executed. ``The company little
      suspected what a noble work I had then in embryo.''
      --Swift.
