'appetition' originates from Latin, specifically the word 'appetitio', where 'ad-' meant 'toward' and 'petere' meant 'to seek or to strive for.'

'appetition' changed from the Medieval Latin word 'appetitio' and entered English via Middle English forms; it eventually became the modern English 'appetition.'

Initially, it meant 'a seeking toward' or 'a striving for'; over time it evolved into its current meaning of 'a desire or appetite, especially of the mind or will.'
