IPA: //baɪˈɒvjʊlə//
KK: /baɪˈɑvələr/
Relating to or derived from two separate eggs, resulting in non-identical or fraternal offspring.
The twins were biovular, meaning they developed from two different eggs.
Biovular is formed from "bio-" (from Greek "bios", meaning life) and "vular" (from Latin "ovulum", meaning egg). The word refers to a condition involving two eggs, particularly in the context of twin pregnancies where two separate eggs are fertilized and develop into two embryos.
Think of 'bio-' meaning life and 'vular' relating to eggs — this helps you remember that 'biovular' refers to a situation involving two eggs.
