Treatise and treaties are two words that are often confused. We will look at the difference between the definitions of treatise and treaties, where these words came from and some examples of their use in sentences.
A treatise is a formal, written discourse that deals with a subject systematically. A treatise is a serious work that examines a subject in depth. The word treatise is derived from the Old French word traitier, which means to set forth in writing or in a speech. The plural of treatise is treatises.
Treaties is the plural form of treaty, which is a formally ratified agreement between two states. A bilateral treaty is a treaty drawn up and agreed upon between two states, a multilateral treaty is drawn up and agreed upon between three or more states. The word treaty is derived from the Latin word tractatus, which means management, discussion or handling.
