Etymology
Origin of addle
First recorded before 1000; Middle English adel “rotten,” Old English adela “liquid, filth”; cognate with Middle Low German adele “liquid manure”
Explanation
Addle is a verb meaning to confuse. When your great uncle Marvin became infirm in his later years, trying to distinguish between you and your cousins tended to addle his brain. Addle is a Middle English word coming from the Old English adela, meaning “liquid filth.” It’s related to the German adel, meaning “mire or puddle.” In the thirteenth century, addle was used to refer to rotten eggs. Now it's used to describe a confused mind. When someone's mind becomes addled — whether it's from age or love or illness — it’s like the brain is rotten.
