'误点' literally combines '误' (wù), meaning 'mistake' or 'error', and '点' (diǎn), meaning 'point' or 'moment'. Together, it refers to a time or place that is incorrect — most commonly used to describe an erroneous or mistaken time, especially in contexts like transportation delays or scheduling errors. While 'point' can suggest location, '误点' almost always refers to time in modern usage, such as a train or flight arriving late (i.e., at the 'wrong time'). It’s a formal, slightly technical term often seen in announcements, news reports, or official notices.

The word implies deviation from a planned or expected schedule, not just any lateness — it carries a nuance of objective error rather than subjective tardiness. It’s frequently paired with verbs like '发生' (to occur) or '导致' (to cause), and commonly modified by quantifiers like '严重' (serious) or '轻微' (minor). Though rare, '误点' can occasionally refer to an incorrect location in specialized contexts (e.g., navigation systems misidentifying a point), but this usage is highly uncommon in daily speech.
