separate-but-equal

the phrase "separate but equal" is a legal doctrine formulated in the united states. it originates from the latin 'separatus', meaning 'disjoined, divided', and the latin 'aequalis', meaning 'uniform, identical, equal'. the phrase was infamously established in the 1896 u.s. supreme court case plessy v. ferguson, which sanctioned state laws requiring racial segregation in public facilities under the condition that the segregated facilities were of equal quality. the narrative of the phrase is one of legal justification for systemic inequality, where the literal promise of "equal" was used to legitimize the enforced reality of "separate," a logic that was ultimately rejected as inherently unequal by the court in brown v. board of education (1954).

this is a hyphenated compound phrase. it is not segmentable into individual morphemes for analysis without losing its specific historical and legal meaning as a fixed term.
