What is the difference between a malaphor and a mixed metaphor?
A malaphor unintentionally combines two idioms or clichés into a nonsensical expression (e.g., “He’s not the brightest crayon in the shed”).
Mixed metaphors combine two metaphors to create an illogical comparison (e.g., “Our love is brighter than the sun. I want to curl up in it and fall asleep”). Mixed metaphors can be created on purpose or by accident.
