KK: /ɑkˈtʌplɪt/
A group of eight things or one of eight babies born at the same time.
The couple was surprised to learn they were expecting octuplets.
Octuplet → It is formed from "octo-" (meaning eight) and "-plet" (from Latin "plere", meaning to fill). The word refers to a group of eight offspring born at one time, thus filling the family with eight children.
Think of the prefix 'octo-' meaning eight, and remember that an 'octuplet' is a set of eight siblings born together.
