Etymology

treaty = treat<negotiate> + y<noun suffix>

  • treat (from Old French traitier, Latin tractare "to handle, manage, negotiate")
  • y (noun-forming suffix indicating a result or action, from Latin -ia or Old French -ie)

Etymology Origin:
The word "treaty" originates from the Old French traité, derived from Latin tractatus ("handling, discussion"), which stems from tractare ("to drag, handle, negotiate"). The suffix -y (via French -ie) nominalizes the action, turning "treat" (to negotiate) into "treaty" (the result of negotiation). The term reflects the historical practice of formalizing agreements through written or diplomatic handling.

Examples
  1. The two nations signed a peace treaty after years of conflict.

  2. The treaty established trade boundaries between the neighboring countries.

  3. Violating the terms of the treaty could lead to diplomatic consequences.

  4. The 1783 Treaty of Paris ended the American Revolutionary War.

  5. Environmental treaties aim to address global climate change collectively.
