 4. To connect with something as a natural or logical consequence or effect; to include necessarily; to imply.

 5. To take in; to gather in; to mingle confusedly; to blend or merge. [R.]

 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.
