Part 379

3. That in which anything is involved, folded, or wrapped; envelope. Sir T. Browne.

4. (Gram.) The insertion of one or more clauses between the subject and the verb, in a way that involves or complicates the construction.

5. (Math.) The act or process of raising a quantity to any power assigned; the multiplication of a quantity into itself a given number of times; -- the reverse of evolution.

6. (Geom.) The relation which exists between three or more sets of points, a.a′, b.b′, c.c′, so related to a point O on the line, that the product Oa.Oa′ = Ob.Ob′ = Oc.Oc′ is constant. Sets of lines or surfaces possessing corresponding properties may be in involution.

7. (Med.) The return of an enlarged part or organ to its normal size, as of the uterus after pregnancy.

In*volve" (?), v. t. [imp. & p. p. Involved (?); p. pr. & vb. n. Involving.] [L. involvere, involutum, to roll about, wrap up; pref. in- in + volvere to roll: cf. OF. involver. See Voluble, and cf. Involute.]

1. To roll or fold up; to wind round; to entwine.

Some of serpent kind . . . involved Their snaky folds.

Milton.

2. To envelop completely; to surround; to cover; to hide; to involve in darkness or obscurity.

And leave a singèd bottom all involved With stench and smoke.

Milton.

3. To complicate or make intricate, as in grammatical structure. "Involved discourses." Locke.

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

He knows His end with mine involved.

Milton.

The contrary necessarily involves a contradiction.

Tillotson.

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

The gathering number, as it moves along, Involves a vast involuntary throng.

Pope.

Earth with hell To mingle and involve.

Milton.

6. To envelop, infold, entangle, or embarrass; as, to involve a person in debt or misery.

7. To engage thoroughly; to occupy, employ, or absorb. "Involved in a deep study." Sir W. Scott.

8. (Math.) To raise to any assigned power; to multiply, as a quantity, into itself a given number of times; as, a quantity involved to the third or fourth power.

Syn. -- To imply; include; implicate; complicate; entangle; embarrass; overwhelm. -- 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.

In*volved" (?), a. (Zoöl.) Same as Involute.
