Etymology

Origin of interposition

1375–1425; late Middle English interposicio ( u ) n < Latin interpositiōn- (stem of interpositiō ), equivalent to interposit ( us ) (past participle of interpōnere to place between) + -iōn- -ion

Explanation

Interposition is intervening by inserting something between two people or groups. One example is your mom's interposition of the family dog between you and your sister in the back seat of the car before you can start fighting. Interposition is from the Latin interpositionem, " insertion," and root words meaning "put" and "between." Sometimes interposition is a physical "putting between," like when one person steps in to break up a shoving match between two others. It can also be a verbal interruption. In U.S. politics, interposition occurs when a state claims that a federal law is unconstitutional and won't enforce it; in that case, the state is figuratively stepping in between its residents and the federal government.
