effervescent

Etymology

It is borrowed from Latin effervēscēns (“boiling up”), the present participle of effervēscō (“to boil up, boil over”),^{[2][3][4][5][6]} from ex (“out, up”), assimilated before f, and fervēscō (“to begin to boil”),^[2][7][6] the inchoative of ferveō (“to be hot, boil”),^[7][6][3] from Proto-Indo-European *bhreu- (“to boil, bubble”).^[2][7][8]

Earliest recorded meaning

In a state of bubbling heat: 1684, in a translation of Bonet's guide for physicians,^[3] a sense the Shorter Oxford finds only in the late 17th century.^[9] Etymonline has the 1680s and Dictionary.com 1675–85.^[2][10]

Semantic evolution

The noun effervescence meant a boiling up from 1651.^[3][11] A bubbling up without necessarily any heat followed in 1685, in Boyle.^[3] The verb effervesce, which Etymonline and Barnhart date to 1702 and the OED to 1747, came later than the adjective,^[2][11][3] and Johnson (1755) still defined it as generating heat by inner motion.^[12] The word's first sense, bubbling with heat, died out in the same century.^[3][9] The figurative use came early: the noun had it by 1744 in the OED, in Johnson's life of Savage,^[3] and the adjective from 1833, in Macaulay's article on Horace Walpole in the Edinburgh Review.^[3][2] The modern literal sense, of something that gives off bubbles, is dated by the Shorter Oxford to the mid 19th century and by the OED's first quotation to 1874.^[9][3]
