Etymology

It is formed from English realize + -ation,[2][3][4] perhaps after French réalisation,[2][4][5] which Merriam-Webster and Dictionary.com give as its direct source, from Middle French realisation, from realiser (“to realize”).[6][7] The French noun is recorded in Middle French legal use in 1509, and in the sense "action of making real" in Cotgrave's dictionary of 1611.[2] The verb is formed from English real + -ize, perhaps after réaliser (“to make real; to convert into assets”).[2][4][3] Its base comes from Old French reel (“real, actual”), from Late Latin reālis (“actual”), from Latin rēs (“thing, matter, property”).[3]

Earliest recorded meaning

The action of making something real, or the process of becoming real: first in Cotgrave's French–English dictionary of 1611.[2][6] Etymonline likewise dates it to the 1610s.[3]

Semantic evolution

An instance of this, a thing made real, followed in 1765.[2] In finance the word came to mean the conversion of an asset, such as property or securities, into money (1753), and the obtaining of a sum or a profit, especially by a sale (1799).[2][8] Webster (1828) listed "the act of realizing or making real" first, then "the act of converting money into land" and "the act of believing or considering as real".[9] The sense now most common, the act of becoming fully aware of something, is dated 1797 by the OED;[2] Etymonline dates the sense "forming a clear concept, perception of the real existence of something" to 1828.[3] It follows the verb, which had taken the sense "understand clearly" by 1775.[3] In the 20th century the noun gained technical uses: in music, the filling out of a harmony from vague or incomplete directions (1911); in statistics, a particular series or value produced by a random process (1941); in linguistics, the expression in sound, writing or grammar of an abstract feature (1950); and in mathematics, a concrete embodiment of an abstract group (1954).[2][8]
