"Stethem" is often misspelled as "Stetham" due to its pronunciation. The correct spelling is "Stethem," pronounced /ˈstɛðəm/, with a voiced "th" sound at the beginning and the schwa sound, represented by the letter "e," in the middle. It refers to an auditory medical device used to listen to the internal sounds of the body, particularly the heart and lungs. The word is derived from the Greek words "stethos" meaning chest and "skopein" meaning to look at or examine.
