Collocations
Pro Tip
Avoid literal confusion
The word 'addle' is almost always used figuratively to describe mental confusion, not physical rot. For spoiled food, 'rotten' or 'spoiled' is more common.
Gold Rule
Figurative vs. Literal
Use 'addle' figuratively for mental confusion (e.g., 'The noise addled my thoughts'). Use 'rotten' or 'spoiled' for food (e.g., 'The egg was rotten').
Word Origin
From Middle English 'adelen' meaning 'to grow rotten', derived from Old English 'eadel' (rotten or spoiled). The figurative sense of mental confusion emerged in the 17th century.
Usage Notes
Most commonly used in informal contexts to describe mental confusion. The literal sense (spoiled eggs) is rare but still recognized.
