Did you know?

Pact has "peace" at its root because a pact often ends a period of unfriendly relations. The word is generally used in the field of international relations, where diplomats may speak of an "arms pact", a "trade pact", or a "fishing-rights pact". But it may also be used for any solemn agreement or promise between two people; after all, whenever two parties shake hands on a deal, they're not about to go to war with each other.
