Word Origin:
[diplomatic diplomatically] early 18th cent. (in the sense ‘relating to official documents’): from modern Latin diplomaticus and French diplomatique, from Latin diploma from Greek diplōma ‘folded paper’, from diploun ‘to fold’, from diplous ‘double’. n. sense 1 (late 18th cent.) is probably due to the publication of the Codex Juris Gentium Diplomaticus (1695), a collection of originals of important public documents, many of which dealt with international affairs.
