IPA: //ˈfaʊlbruːd//
KK: /faʊlˌbrud/
A serious illness that affects the larvae of honeybees, caused by certain types of bacteria.
The beekeeper had to treat the hive for foulbrood to save the remaining bees.
Foulbrood is formed from "foul" (from Old English *fūl*, meaning dirty or unclean) and "brood" (from Old English *brōd*, meaning offspring or young). The term foulbrood refers to a disease affecting the young of bees, indicating that the brood is unclean or diseased.
Think of 'foul' meaning dirty and 'brood' referring to young offspring — this helps you remember that foulbrood describes a disease affecting the young bees.
