stabilize

Etymology

The OED takes it as borrowed from French stabiliser, from Latin stabilis (“firm, steadfast”), the source of stable.^[2][3] Etymonline thinks it probably a back-formation from English stability, or else from the French verb;^[4] the Shorter Oxford derives it from the adjective stable with -ize, influenced by the stem of stability,^[5] Merriam-Webster and Dictionary.com from stabile with the same suffix,^[6][7][8] and Klein from the Latin adjective with the suffix.^[3] The Latin adjective meant "able to stand" and goes back to Proto-Indo-European *sta- (“to stand, make or be firm”).^[4] Earlier English verbs with the same meaning were stabilitate (1640s) and the verb stable (about 1300), from establir.^[4]

Earliest recorded meaning

To give stability to a ship: 1861, in W. Froude's Rolling of Ships;^[2][9] Etymonline also dates it to 1861, originally of ships.^[4] Merriam-Webster gives 1861 as well.^[6]

Semantic evolution

From ships the verb spread to other objects; from 1875 it meant to give anything a stable character or value.^[2][9] Weekley notes a military sense, to consolidate a position, as a new word of 1918 after the French verb;^[10] in the same year it was used of fixing a scale of payments or prices.^[2] The economic use (stabilizing a currency or prices) and the use of aircraft and rockets kept by a stabilizer were common in the 20th century.^[5][6] The intransitive sense, to become stable, especially to stop varying in value, is first recorded in Webster's Third (1961),^[2] although the Shorter Oxford dates it to the mid 20th century.^[5]
