Synonyms Interpose, Interfere, Intermeddle, Intervene. To intermeddle is both unwelcome and impertinent. To interfere is unwelcome to the one interfered with, and often but not necessarily improper: as, the court interfered to prevent further injustice. In this sentence interposed would have been a very proper word to express the benevolence and helpfulness of the action of the court, while interfere suggests the checking of what was going on and the balking of selfish plans. Interpose in its personal application is generally used in a good sense. Interfere may be used of a person or of a thing; intermeddle only of a person or the act of a person. Intervene is used only of things literally or figuratively coming between, and hence without either praise or blame: as, several weeks intervened; an intervening piece of woods. A piece of woods may interfere with a view; we must interfere in a quarrel when life is threatened. See intrude.
In chess, to put (a piece) between the checked king and the checking piece.
