A formally concluded and ratified agreement between states or other international entities.

Always involves two or more sovereign entities and is legally binding under international law.

The story behind the word. The word 'treaty' comes from Old French `traité`, which meant 'negotiation' or 'agreement.' This in turn derived from the Latin `tractare`, meaning 'to handle, manage, discuss.' So, a treaty is something that has been carefully 'handled' or 'discussed' to reach a formal, binding agreement between nations.
