'suture' originates from Latin, specifically the word 'sutura', where 'suere' meant 'to sew'.

'sutura' passed into Late Latin and Medieval Latin and then into Middle English (via Old French influence) as 'suture', eventually becoming the modern English word 'suture'.

Initially it meant 'a sewing or seam', and over time it developed the specialized medical sense of 'a stitch used to join biological tissue' while retaining the general sense of a sewn seam.
