Etymology
the word 'peritoneum' entered english via late latin from the greek 'peritonaion', meaning "that which is stretched around". this greek term is a compound of the prefix 'peri-' (around) and the verb 'teinein' (to stretch), with the neuter participial suffix '-on'. the literal greek sense describes the membrane as something "stretched around" the abdominal cavity. in medical terminology, it was adopted into latin and subsequently english to specifically denote the expansive, enveloping serous sac that lines the abdominal wall and invests the viscera, perfectly capturing its anatomical function through its etymological construction.
