Root Explanation

Spiracular → It is formed from "spiraculum" (from Latin, meaning a small opening or vent) and the suffix "-ar" (indicating relating to). The word "spiracular" refers to something that relates to or has the function of a small opening or vent, particularly in the context of breathing or respiration.

Memory Tip

Think of a small 'opening' ('spiraculum') that is 'related to' ('-ar') breathing — that's why spiracular refers to something that has to do with breathing openings.
