misname

This verb carries a neutral to slightly apologetic tone, typically used when a factual error has occurred regarding a person's identity or a thing's classification. It is more precise than "mistake," which is a general term for any error, as "misname" specifically targets the act of labeling or addressing.

In professional or formal settings, using this word often precedes an apology to acknowledge a social faux pas. It differs from "mislabel" in that "misname" is more frequently applied to people or titles, whereas "mislabel" usually refers to physical tags, categories, or commercial products.
