Subduct is formed from "sub-" (meaning under) and "ducere" (meaning to lead). The word describes the act of leading something under, often used in geological contexts to refer to one tectonic plate being forced under another.
Think of something being 'led under' ('sub-') — that's why subduct means to lead something beneath another.
