What does diplomatical mean?
Diplomatical is an adjective meaning relating to diplomacy, or showing the tact and finesse expected of a skilled negotiator. It carries precisely the same senses as its far more common counterpart 'diplomatic': it can describe matters connected to the conduct of relations between nations, as in diplomatical negotiations or correspondence, or characterize a person's manner as tactful and careful not to give offence. In practice, the longer form has largely fallen out of use and survives mainly in older writing or in consciously formal style, so modern readers will encounter it rarely. When it does appear, its connotations are positive — prudence, discretion, and social skill. The word derives from the same root as 'diploma' and 'diplomacy', tracing back to the Greek 'diplōma', a folded document, reflecting the folded papers once carried by envoys. For contemporary writing, 'diplomatic' remains the standard choice, but knowing 'diplomatical' helps readers interpret historical and literary texts where the variant appears.

Adding '-al' to a word that already ends in '-ic' usually signals an older, now-fading form — and 'diplomatical' is exactly that: a once-acceptable variant that modern usage has all but retired.

Etymology of diplomatical
Diplomatical derives from 'diplomatic', which traces through French 'diplomatique' to the Greek 'diplōmatikos', from 'diplōma' meaning a folded or doubled document — the papers of privilege carried by envoys. The '-al' ending produced a doublet-style variant common when adjectives were formed on '-ic' stems. Both forms entered English around the late 18th century as diplomacy became a settled term for the conduct of international relations, with 'diplomatic' ultimately prevailing in standard usage.
