What does eyewitness mean?
An eyewitness is a person who has seen an event — typically a crime, accident, or other significant occurrence — happen directly with their own eyes, and who can therefore describe it firsthand. The word carries a strong connotation of immediacy and credibility: an eyewitness account is presumed more reliable than hearsay because it rests on personal observation rather than secondhand information. For this reason, it appears constantly in journalism ('according to eyewitnesses at the scene') and in legal settings, where eyewitness testimony can be decisive in trials. The term is most often used attributively, as in 'eyewitness report' or 'eyewitness video'. Interestingly, modern psychology has complicated its reputation: research shows that human memory is malleable, and even sincere eyewitnesses can misidentify people or reconstruct details incorrectly, which is why courts now treat such testimony with careful scrutiny. Still, the word retains its everyday force as shorthand for someone who was actually there.

Psychologists have shown that eyewitness memory is surprisingly unreliable — confident identifications can still be dead wrong.

Etymology of eyewitness
Eyewitness is a straightforward English compound of 'eye' and 'witness', formed within English rather than borrowed from another language. The noun 'witness' derives from Old English 'witness', related to 'wit', meaning knowledge or understanding, from the Proto-Germanic root *witaną, meaning 'to know'. Cognates appear across the Germanic family, including Old Norse 'vitr' (wise) and German 'wissen' (to know). The compound emerged in English by the late sixteenth century.
How eyewitness is actually used
Neutral in register and common in both journalism and legal contexts. Often used attributively before nouns such as 'account', 'testimony', and 'report'. It emphasizes direct visual perception, which is why it is favored in reporting crime and accidents.
Easily confused with eyewitness
A witness may know something secondhand (e.g. from documents), while an eyewitness specifically saw the event with their own eyes.
