Etymology
The word 'decouple' is a modern formation built from established English components. The prefix 'de-', derived from Latin, carries a sense of reversal or removal. It is attached to the verb 'couple', which entered English from Old French 'coupler', itself from Latin 'copulare' meaning "to join together." The literal construction, "to un-join," directly informs its modern technical and figurative meanings. It first emerged in the mid-20th century, primarily in scientific and economic contexts, to describe the deliberate separation of interconnected systems, such as disengaging railway carriages or making an economy independent from external factors.
