affilier[1]
Etymology
It is borrowed from Medieval Latin affiliō (“to adopt as a son”), a legal term,[2][3][4] formed from ad- and Latin fīlius (“son”).[3][1] The Medieval Latin verb is found as early as 984.[2]
Littré compares Old Occitan afilhar, Catalan afillar and Spanish ahijar, and thought from them that the French word was older than its records.[5]
Earliest recorded meaning
It is first found in the 14th century, in L'Arbre des batailles, meaning “to adopt as a son”: the pope could give Queen Joan the power to have affilié le roy Loys “adopted King Louis” as her son.[2][6]
Semantic evolution
The Trévoux dictionary of 1752 already called this sense old.[2] In 1701 Furetière records a religious sense, to make someone a sharer in all that is holy in a religious order, where the idea of sonship is still felt.[2][3][7] In 1762 the Académie has the reflexive of one society taking on a similar one as a daughter, with the example of the Académie française and provincial academies.[2]
The modern sense, to admit as a member of a group, dates from the 18th century (1732 in Bloch and Wartburg and the Petit Robert) and spread during the Revolution, with the reflexive “to join” from 1791.[3][4][8] The Académie records this reflexive in 1798.[2]
