Root Explanation

Uncoupler → It is formed from "un-" (meaning not or opposite of) and "coupler" (from the verb "couple", which comes from Latin "copulare", meaning to join or link). The word "uncoupler" refers to something that separates or disconnects things that were previously joined or linked.

Memory Tip

Think of 'not joining' ('un-') something that was 'linked' ('couple'). This helps you remember that an uncoupler is something that separates or disconnects.
