The word 'synod' originates from the Greek synodos, meaning "a meeting, assembly," which itself is a compound of syn- ("together") and hodos ("way, journey, path"). The literal sense was "a coming together on the same path." This term was adopted into Late Latin as synodus and then into Old English as sinoth, specifically for ecclesiastical assemblies. The semantic evolution perfectly captures the logic of people traveling from different places to converge on a common path for the purpose of deliberation, a concept that has been retained in its modern usage for formal church councils and, by extension, any deliberative assembly.
