Root Explanation

Fathomless → It is formed from "fathom" (from Old English *fæðm*, meaning to embrace or encircle) and "-less" (meaning without). The word "fathomless" describes something that is without measure or depth, often used to refer to something immeasurable or unfathomable.

Memory Tip

Think of 'fathom' as embracing or encircling something, and when you add '-less', it means without that measure. So, fathomless means without measure or depth.
