'anfractuosity' originates from Latin, specifically the word 'anfractuositas,' where 'anfractus' meant 'a winding or bending.'

'anfractuositas' transformed into the Medieval Latin 'anfractuositas,' and eventually became the modern English word 'anfractuosity.'

Initially, it meant 'a winding or bending,' but over time it evolved into its current meaning of 'a winding or intricate turn, passage, or path.'
