The word "summation" derives from the Latin summa (meaning "highest point" or "total"), which evolved into the English word "sum." The suffix "-ation" (from Latin -atio) denotes an action or process. Historically, "summation" emerged in the 18th century to describe the mathematical act of totaling, later expanding to general usage for any cumulative process or concluding statement. The logic reflects progression from concrete addition to abstract synthesis.
