Agglutinative \Ag*glu"ti*na*tive\, a. [Cf. F. agglutinatif.]
   1. Pertaining to agglutination; tending to unite, or having
      power to cause adhesion; adhesive.

   2. (Philol.) Formed or characterized by agglutination, as a
      language or a compound.

            In agglutinative languages the union of words may be
            compared to mechanical compounds, in inflective
            languages to chemical compounds.      --R. Morris.

            Cf. man-kind, heir-loom, war-like, which are
            agglutinative compounds. The Finnish, Hungarian,
            Turkish, the Tamul, etc., are agglutinative
            languages.                            --R. Morris.

            Agglutinative languages preserve the consciousness
            of their roots.                       --Max
                                                  M["u]ller.
