'dot' originates from Middle English, specifically the word 'dott,' where 'dott' meant 'head of a boil or pimple.'

'dott' changed from the Old English word 'dott' and eventually became the modern English word 'dot'.

Initially, it meant 'head of a boil or pimple,' but over time it evolved into its current meaning of 'a small round mark or spot.'
