An examination is a careful look at something to understand it better, find problems, or judge its quality. It can also mean a formal test of knowledge or ability, especially in school.
It comes from Latin 'examinatio', from 'examinare', meaning 'to weigh, test', originally referring to the tongue of a balance scale. The idea of careful weighing turned into testing and inspecting.
The root image of 'examination' is a scale trying to balance—your answers on one side and the standard on the other. Whether it’s a medical exam or a math exam, someone is quietly weighing how well reality matches the ideal.
