Etymology
The word 'convention' originates from the Latin conventio, meaning "a meeting, assembly, agreement," itself derived from convenire ("to come together, assemble"). This verb is a compound of the prefix con- ("together") and venire ("to come"). The core logic of the word has remained remarkably consistent: from the literal act of people "coming together" for a meeting, the meaning extended to the formal agreements made at such gatherings, and further broadened to signify any customary practice that a society implicitly "agrees" to follow. Thus, the journey from a physical gathering to an abstract social norm is built upon the foundational idea of collective assembly and accord.
