Here's a breakdown of the meaning:
* Cheir (χειρ) - hand
* Ergon (ἔργον) - work
So, a surgeon is literally a "hand worker," specifically one who uses their hands to perform surgical procedures.
Today, "surgeon" refers to a medical professional who is licensed and trained to perform surgeries. They use specialized instruments and techniques to treat illnesses, injuries, or deformities through surgical procedures.
