The word **拖把** (tuōbǎ), meaning "mop," is a straightforward compound formed by combining the verb **拖** (tuō), which means "to drag" or "to mop," with the noun **把** (bǎ), which signifies a handle or something held in the hand. Therefore, the term literally and logically denotes "a handle for dragging," perfectly describing the tool's primary function—a handled implement used to drag a cleaning head across a floor. This type of word formation, where an action and its associated object are combined to name a tool, is common and highly intuitive in Chinese.
