Decouple is a verb that means to separate or disentangle.

The word couple is often used as a verb meaning ‘to join two or more things.’ When we add the prefix D-E, we get the opposite. So our word of the day means to separate or dissociate things. Example:

Before I could remove the boxes from my trunk, I first had to decouple them. All stuck together, they were too large to yank out.
