Etymology Origin:
The word "party" originated from Old French partie (a part or division), derived from Latin partita (divided). Initially, it referred to a "division of people" (e.g., political factions or legal sides). By the 18th century, it evolved to denote social gatherings, emphasizing the idea of a "group united for a purpose." The dual meaning—political group and festive gathering—reflects the word's logical progression from "division" to "collective activity."
