[verb] To look at something or someone very carefully in order to learn more about it, check it, or judge it. It can also mean to test someone's knowledge by asking them questions.
Every time you sit an exam, you are being weighed — literally — on ancient Roman scales.
The story of 'examine' begins with a small but vital piece of Roman engineering: the balance scale. The Latin word 'examen' referred to the tongue or pointer of a balance — the thin rod that swung left or right to show which side was heavier. This word itself came from 'exigere', meaning 'to drive out' or 'to weigh', which was formed from 'ex-' (out) combined with 'agere' (to drive or act). So at its very heart, to examine something was to weigh it, to let it hang in the balance and see how it measured up.
From this concrete image of a physical scale, Latin speakers extended 'examen' into a metaphor. To examine an idea, a person, or a situation meant to weigh it carefully in the mind — to test its truth, its worth, its correctness. The verb form 'examinare' developed naturally, meaning 'to weigh, to test, to consider with care'. Roman writers used it in legal and philosophical contexts, where ideas and testimonies were 'weighed' for their credibility, much as goods were weighed for their value in the marketplace.
The word moved from classical Latin into Old French as 'examiner', keeping the sense of testing and scrutinising. Old French was the dominant language of educated and official life in England after the Norman Conquest of 1066, and it served as the great conveyor belt bringing Latin-rooted vocabulary into English. It was through this route — Latin 'examinare' → Old French 'examiner' → Middle English 'examinen' — that the word arrived in English in the late 14th century. Early English uses appear in legal and ecclesiastical writing, where church authorities would 'examine' witnesses and defendants.
Chaucer and his contemporaries used the word in ways that feel surprisingly modern — to look closely, to question, to investigate. Over the following centuries, the meaning broadened steadily. By the 16th and 17th centuries, 'examine' was being used in scientific writing to describe the careful observation of natural phenomena, fitting perfectly into the spirit of the new empirical science that was transforming European thought. To 'examine' a specimen under a lens, or to 'examine' the stars, carried the full weight of that original sense: to weigh evidence carefully before reaching a conclusion.
The noun 'exam', a shortened form of 'examination', did not appear until the 19th century, when formal written tests became common in schools and universities. It is a remarkably recent invention in the life of the word — yet it is now the form most people encounter first. Interestingly, several close relatives of 'examine' are still alive in everyday English: 'exact' comes from the same root 'exigere', and 'essay' shares a cousin relationship through the idea of testing or trying. Even the word 'agent' traces back to 'agere', the same Latin verb that gave 'examine' its ancient driving force. The scales of ancient Rome, it turns out, are still tipping quietly inside our language.
