the term "summitry" is a modern diplomatic coinage, constructed in the mid-20th century during the cold war era. it directly builds upon the noun "summit," which derives from latin summus, meaning "highest," a superlative form related to superus (upper). the metaphorical extension from a geographical peak to a high-level conference between leaders is intuitively clear. the suffix "-ry," of old french origin, is appended to form a noun denoting the collective practice or system of conducting such top-level meetings, analogous to words like "archery" or "dentistry."

Structure: summit (highest point) + ry (collective practice) - summit: from latin summus (highest), functioning as the core noun denoting the peak or highest level of diplomatic engagement. - ry: from old french -erie, a noun-forming suffix indicating a collective practice, art, or condition, functioning to denote the associated activity or system.
