To cut or excise; to cut away or remove by cutting.
From Latin 'accidere' meaning 'to cut to' or 'to cut away,' from 'ad-' (to) plus 'caedere' (to cut). Related to 'excise' and 'incise,' all sharing the Latin 'caedere' root.
This is an ultra-rare medical/surgical term that survives mainly in medical Latin—when surgeons 'accise' tissue, they're using a word that's over 2,000 years old but sounds like jargon even to most English speakers.
