double-standard

The term 'double-standard' is a modern English compound, formed by combining two words of distinct origins. 'Double' traces back to the Latin duplus, meaning 'twofold', which itself derives from the Proto-Indo-European root dwo-, meaning 'two'. 'Standard' entered English via Old French, originally denoting a military flag as a rallying point, a concept of authority and measure from Germanic roots. The compound emerged in the late 19th century, logically combining the idea of 'two' ('double') with a 'benchmark or norm' ('standard') to create a metaphor for applying two different sets of rules or judgments where one should suffice, thus capturing the essence of hypocrisy and unequal treatment.

Structure: double (twofold) + standard (level of quality) - double: From Latin duplus (twofold, double). In this compound, it functions as an adjective meaning 'consisting of two'. - standard: From Old French estandart (rallying point, military flag), of Germanic origin. In this compound, it functions as a noun meaning 'a level of quality or attainment used as a measure'.
