A type of thorny shrub found in Europe that produces small, dark fruits and white flowers, often used to flavor drinks like sloe gin.
The blackthorn bushes were full of white blossoms in the spring.
Blackthorn is formed from "black" (from Old English "blæc", meaning dark or without light) and "thorn" (from Old English "þorn", meaning a thorny plant). The word "blackthorn" refers to a thorny shrub that has dark-colored branches and fruits.
Think of the word 'black' meaning dark and 'thorn' referring to a thorny plant — together, they describe a dark, thorny shrub.
