Etymology: "Climactic" is a straightforward formation: English "climax" plus the adjective-forming suffix "-ic," which English took from Latin "-icus" through Old French and Middle English. The suffix itself is ancient, a Greek-derived ending that English absorbed in countless adjectives such as "magic" and "public." The more interesting detail is the base word. "Climax" comes from Greek "klimax," meaning "ladder" or "staircase," which is why the idea of a dramatic peak carries a sense of ascent, of one step after another rising toward the top. Rhetoricians later used the same Greek word for a figure of speech in which phrases build in strength toward a final, weightiest one. "Climactic" itself is a comparatively modern adjective. Its form was shaped on the analogy of "syntactic," a word whose ending matches the same pattern, which explains why it looks like a regular extension of "climax" even though the pairing was not inevitable.
