symbiotic

Etymology

It is formed from English symbiosis + -otic.^[2][3] Etymonline describes it as the stem of the noun with -ic,^[4] Dictionary.com as a shortened form of the noun with -tic,^[5] and Barnhart as formed on the analogy of pairs such as neurosis and neurotic, osmosis and osmotic.^[6] Symbiosis, used in biology from the 1870s, is from New Latin symbiosis,^[7][4][6] from Ancient Greek συμβίωσις (sumbíōsis, “a living together, companionship”), from συμβιόω (sumbióō, “to live together”), from σύμβιος (súmbios, “living together; companion, partner”), formed from σύν (sún, “together”) and βίος (bíos, “life”).^[7][4][8] Klein instead derived the adjective from Ancient Greek συμβιωτικός (sumbiōtikós), from συμβιωτής (sumbiōtḗs, “one who lives with, companion”), from the same verb.^[9] The less common form symbiotical adds -al.^[2][4]

Earliest recorded meaning

Living in or relating to symbiosis: 1882, in the Academy of 4 February.^[7][6][4] The adverb symbiotically followed in 1888.^[6]

Semantic evolution

The adjective followed the noun closely: symbiosis had meant communal life since 1622, but became a biological term for the close association of two different organisms only in the 1870s and 1880s.^[7][4][6] The noun was given a transferred, non-biological sense by 1921, in Shaw's Back to Methuselah,^[7][4] and Etymonline dates the adjective's use of human activities to 1951.^[4] In this wider use it describes people or groups that depend on or benefit each other.^[10][11]
