Have you ever heard of the term dedendum in gears?

No, I haven't! What does it mean?

Root Explanation

Dedendum is derived from the Latin root "dedere" (meaning to give up or surrender) and the suffix "-ndum" (indicating something that must be done). The term refers to something that must be given up or surrendered.

Memory Tip

Think of 'giving up' ('dedere') something that 'must be done' ('-ndum') — that's why dedendum means something that must be surrendered.
