Etymology

The word "congratulatory" stems from Latin roots. The prefix "con-" (together) combines with "gratulari" (to rejoice, derived from "gratus," meaning "pleasing" or "thankful"). The suffix "-ory" transforms the verb into an adjective, denoting a quality or action. Historically, it evolved through Late Latin "congratulatorius" and Middle English to its current form, retaining the core idea of collective joy or praise.
