Root Explanation
Azygos → It is derived from the Greek word "a-" (meaning without) and "zygos" (meaning yoke or pair). The term originally referred to something that is unpaired or not yoked together, often used in anatomical contexts to describe structures that are singular or not paired.
Memory Tip
Think of 'without' ('a-') and 'pair' ('zygos') to remember that 'azygos' refers to something that is unpaired or singular.
