The word "convention" traces back to Latin conventio, from convenire ("to come together"). The root vent (from Latin venire, "to come") appears in many English words (e.g., "advent," "invent"). Over time, "convention" evolved from the literal sense of "gathering" to abstract meanings like "agreement" or "custom," reflecting how collective gatherings often lead to shared norms.
