It is a medical instrument to listen to the heartbeat or the sound of breathing. Greek etymology takes some licenses; the first is in 963; 964; 951; 952; 959; 962; ( stethos "chest") , since in truth it is also used on the back or belly, and then uses the word 963; 954; 959; 960; 949; 953; 957; ( scopein "observe" ) , which is associated more with sight than hearing, but which is ultimately interpreted as "examine". See stethoscope, doctor/stethoscope.
