IPA: /ˌsuːpərfɪˈteɪʃən/

The process of developing a second fetus while already having one in the uterus, which can happen in some animal species.
Superfetation is rare in humans but can occur in some animals, leading to the birth of siblings at different stages of development.
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.
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.
