The word **班车** is a compound noun formed by combining two characters: **班** (bān), meaning "scheduled shift" or "regular run," and **车** (chē), meaning "vehicle." Together, they create a new meaning that is more specific than the sum of its parts, referring to a "shuttle bus" or "regular bus service" that operates on a fixed route and timetable, typically for commuting purposes such as company or school transportation. This formation follows the common Chinese lexical pattern of modifying a general category (车, vehicle) with a descriptive attribute (班, scheduled) to specify a particular type of that category.
