Sense: verb/1
Decouple is more technical and abstract than separate, disconnect, or detach. You use it when two things have been moving together, affecting each other, or built into the same system, and you want that link removed so they can act more independently. Separate is the broad everyday word for putting things apart. Disconnect often suggests breaking a direct link, especially in technology or communication. Detach is more physical and usually means taking one thing off another surface or object. A city can decouple ticket prices from fuel costs, but you would usually separate two files, disconnect a cable, or detach a label from a box.

Etymology
Decouple is a modern English formation built from the prefix de-, meaning to remove or reverse, and couple, a word for joining things together. Couple came into English through Old French from Latin roots meaning a bond or link. The newer verb first suggested taking connected parts apart, then broadened to business, policy, and technology contexts where two systems, trends, or prices are no longer made to move together.
