Pronunciation

  • /ɹəˈvɜː(ɹ)sɪbəl/[1]

Etymology

It is formed from English reverse + -ible.[2][3][4][5][6] The OED compares French réversible, recorded from 1610, at first in legal use,[2] and Johnson took it from French.[7] The verb reverse is from Old French reverser (“to turn around”), from Late Latin reversō (“to turn about”), a frequentative of revertō (“to turn back, return”).[3] An earlier spelling with the suffix -able is recorded from the 1580s.[3][2]

Earliest recorded meaning

Able to be reversed: 1632, in Edward Reynolds's Explication of the 110th Psalm.[2][5] Etymonline dates it to the 1640s.[3]

Semantic evolution

Johnson (1755) gave only the general sense "capable of being reversed".[7] In the 19th century the word gained several special senses: of cloth or a garment, finished so that either side can be worn outward (1853), with a reversible for such a garment the same year;[2][5][3] of a ship's propeller (1862);[2] and in science, of a process that can run in either direction, first in thermodynamics in W. Thomson's paper of 1852, then of chemical reactions (1883), electric cells (1885) and colloids (1900).[2] In West Yorkshire a reversible was a double cloth with a better face than back.[8]
