Root Explanation

Superfetation → It is formed from "super-" (meaning above or beyond) and "fetare" (from Latin, meaning to conceive). The word describes a condition where a second conception occurs during an ongoing pregnancy, hence the idea of conception occurring beyond the usual limits.

Memory Tip

Think of 'super-' meaning 'above' or 'beyond' and 'fetare' meaning 'to conceive' — this helps you remember that superfetation refers to a conception that occurs beyond the normal limits of pregnancy.
