climactic

Etymology

It is formed irregularly from English climax + -ic,^[2][3][4][5] probably partly after syntactic, the adjective of syntax,^{[2][6][7][8][9]} and partly after climacteric.^[2][3][5] Barnhart notes that it was not taken from a Greek form, the genitive of the Greek noun being κλίμακος (klímakos).^[6] Climax is from Latin clīmax, from Ancient Greek κλῖμαξ (klîmax, “ladder; in rhetoric, a rising series”),^[2][7][10] probably from the base of κλίνω (klínō, “to lean”),^[2] from Proto-Indo-European *klei- (“to lean”).^[7][10] The adverb climactically is recorded much earlier, in 1622,^[2] and in 1638 T. Herbert wrote of a "Clymactick yeare", apparently a variant of or error for climacteric.^[2]

Earliest recorded meaning

Forming the most important or intense point of something: 1747, in S. Foote's Treatice upon Passions.^[2] Other dictionaries date the adjective later: Etymonline to 1832,^[7] Merriam-Webster Unabridged to 1870,^[8] Barnhart to 1872,^[6] and the Shorter Oxford to the late 19th century.^[5]

Semantic evolution

The adjective followed the senses of climax, which entered English in the 16th century as a term of rhetoric, a chain of clauses rising in force.^[7][2] Climactic was used of the culminating point of a story or event from 1747; in W. Minto's Manual of English Prose Literature (1872) it was applied to the rhetorical figure itself.^[2][6] The sexual sense, of or relating to orgasm, followed in 1913.^[2] Because it was formed irregularly, the word is sometimes confused with climatic.^[11][9]
