Etymology

From French subluxation, from New Latin subluxatio, from subluxare (“to subluxate, to partially displace”) + -atio (“-ation: forming abstract nouns”), from sub- (“sub-: under, below, lesser”) + luxare (“to dislocate; to displace”) after the model of Ancient Greek παράρθρημα (parárthrēma). Equivalent to sub- + luxation.
