Syn: To imply; include; implicate; complicate; entangle;
     embarrass; overwhelm.
Usage: To {Involve}, {Imply}. Imply is opposed to express, or
       set forth; thus, an implied engagement is one fairly
       to be understood from the words used or the
       circumstances of the case, though not set forth in
       form. Involve goes beyond the mere interpretation of
       things into their necessary relations; and hence, if
       one thing involves another, it so contains it that the
       two must go together by an indissoluble connection.
       War, for example, involves wide spread misery and
       death; the premises of a syllogism involve the
       conclusion.
