To _interpose_ is to place or come between other things or persons, usually as a means of obstruction or prevention of some effect or result that would otherwise occur, or be expected to take place. _Intercede_ and _interpose_ are used in a good sense; _intermeddle_ always in a bad sense, and _interfere_ frequently so. To _intercede_ is to come between persons who are at variance, and plead with the stronger in behalf of the weaker. One may _interpose_ with authority; he _intercedes_ by petition. To _intermeddle_ is to thrust oneself into the concerns of others with a petty officiousness; _meddling_ commonly arises from idle curiosity; "every fool will be _meddling_," _Prov._ xx, 3; to _interfere_ is to intrude into others' affairs with more serious purpose, with or without acknowledged right or propriety. _Intercept_ is applied to an object that may be seized or stopped while in transit; as, to _intercept_ a letter or a messenger; _interrupt_ is applied to an action which might or should be continuous, but is broken in upon (L. _rumpere_, to break) by some disturbing power; as, the conversation was _interrupted_. One who _arbitrates_ or _mediates_ must do so by the request or at least with the consent of the contending parties; the other words of the group imply that he steps in of his own accord.

To _involve_ (L. _in_, in, and _volvo_, roll) is to roll or wind up with or in so as to combine inextricably or inseparably, or nearly so; as, the nation is _involved_ in war; the bookkeeper's accounts, or the writer's sentences are _involved_. _Involve_ is a stronger word than _implicate_, denoting more complete entanglement. As applied to persons, _implicate_ is always used in an unfavorable sense, and _involve_ ordinarily so; but _implicate_ applies only to that which is wrong, while _involve_ is more commonly used of that which is unfortunate; one is _implicated_ in a crime, _involved_ in embarrassments, misfortunes, or perplexities. As regards logical connection that which is _included_ is usually expressly stated; that which is _implied_ is not stated, but is naturally to be inferred; that which is _involved_ is necessarily to be inferred; as, a slate roof is _included_ in the contract; that the roof shall be water-tight is _implied_; the contrary supposition _involves_ an absurdity.
