舌

1. Anatomical: The tongue. In medical or physiological contexts, it may serve as a diagnostic marker (e.g., color, coating).

2. Rhetorical: Speech, specifically regarding the manner or instrument of delivery rather than the content. Often emphasizes eloquence and persuasiveness, or conversely, deceit and gossip.

3. Technical: The clapper of a bell.

Functions almost exclusively as a noun. It does not typically function as a verb ("to speak"); if it appears in a verbal position, look for an omitted verb or a descriptive phrase regarding physical movement.

Contrast with 口 (mouth): The use of 舌 usually draws attention to the act of articulation, the physicality of speech, or the specific skill or malice of the speaker’s rhetoric.

Note the use of physical imagery—such as the tongue protruding or being silenced/cut—which typically denotes extreme emotion or punitive action.
