ETYMOLOGY: After the dentist Charles R. Stent (1845-1901). Stent did pioneering work in coming up with a compound that made better molds for dentures. Later, the compound was used to make casts of other body parts and cavities. Stents correct stenosis (narrowing). Earliest documented use: 1878. The word stentorian is also an eponym, but it came from someone else

STERT - a snorer

P.S.TENT - a portable outdoor shelter brought along as an afterthought

S-TEST - what statistician William S Gossett was fiddling with just before he conceived Student's t-test
