Origin

The character 号 most likely developed from a picture of an open mouth or a horn, reflecting the original meaning of calling out or shouting. The vertical line represents sound or breath issuing forth, while the curved or box-like shape suggests an open mouth or the bell-like shape of a horn used to make announcements. From this basic sense of "calling out" or "announcing," the meaning expanded to include names and titles that people call things by, and eventually the more abstract sense of "number" or "item" as a way to label and identify things. This shift from a physical action of calling to a label or designation is why the character can mean both "to shout" and "nickname" or "number."
