- intestines (n.)
- "bowels," 1590s, from intestine, based on Latin intestina, neuter plural of intestinus (adj.) "internal, inward, intestine," from intus "within, on the inside," from PIE *entos, suffixed form of root *en "in" (see in (adv.)). Compare Sanskrit antastyam, Greek entosthia "bowels." The Old English word was hropp, literally "rope."
