用法筆記
Frequently used in legal and news reporting contexts. Unlike the broader term 'witness', which can refer to anyone who gives evidence in court, 'eyewitness' specifically requires that the person saw the event firsthand. The noun is almost always followed by 'to' when specifying the event (e.g., 'eyewitness to the robbery').
