réaliser[1]

Etymology

It is a learned derivative of réel, after Medieval Latin reālis (“real, relating to things”),[2][3][4][5][6] from Latin rēs (“thing”).[7][1] Bloch and Wartburg and Wiktionary take it from the old form real with the suffix -iser.[7][1] English realize (1610s) was borrowed from it.[8]

Earliest recorded meaning

It first appears in law, in the customs of Boulogne (1495): acquestes non réalisées “acquisitions not made real”, that is, not secured on property;[9][4] the GLLF glosses this first sense as converting a capital by contract into periodic payments.[5]

Semantic evolution

Long a legal term of northern France (still unknown in Paris in 1605), it was used in réaliser un contrat (1507), to acknowledge a contract so as to acquire a real right, and disappeared from law with the Ancien Régime.[4][9] In finance, from about 1719 under Law's system, it meant “to convert into money”;[7][4][9] Voltaire calls it a new term brought into the language by that system.[7][4][9] From it came réaliser un bénéfice (Stendhal, 1835).[9][4]

The general sense “to make real” is in Cotgrave (1611), and the Académie has réalisez vos promesses in 1718;[9] se réaliser “to come true” dates from before 1742 and “to fulfil oneself” from 1850 (Sainte-Beuve).[9][4] It took the sense “to make a film” in 1908, and is also used in music for realizing a harmony (1853).[9][4]

Translators from English first used it for “to become aware of” (Baudelaire's Poe, 1858); this sense spread from 1895 (Paul Bourget) despite strong criticism, and Proust still printed it in italics.[4][7][9]
