'toadstool' originates from Middle English, specifically the word 'tadde-stole,' where 'tadde' meant 'toad' and 'stole' meant 'stool.'

'tadde-stole' transformed into the modern English word 'toadstool' through Middle English.

Initially, it meant 'a stool for toads,' but over time it evolved into its current meaning of 'a type of poisonous mushroom.'
