鼓

• Noun: A drum, primarily used for signaling, timing, and military mobilization.
• Verb (Literal): To beat or strike a drum; to produce sound via impact on a membrane.
• Verb (Extended): To rouse, incite, stir up, or encourage.

Functions as both a noun and a transitive verb. When used in the sense of "rousing" or "inciting," it often carries a causative nuance.

• vs. 擊 (strike/attack): While both involve hitting, 鼓 implies rhythm, resonance, and signaling, whereas 擊 typically denotes a decisive blow or combat strike.
• vs. 敲 (knock/tap): 鼓 involves the vibration of a membrane; 敲 is generally a sharper, more localized impact.
• vs. 鳴 (sound/cry): 鳴 refers to the sound itself or the act of voicing; 鼓 refers specifically to the act of producing sound through percussion.

Variants include U+76B7, U+9F14, and U+29272.

The presence of the leather/skin radical (皮) identifies the object as a membrane-based instrument, distinguishing its "strike" from that of metal or wood.

In early texts, "rousing" is often literal—such as calling soldiers to arms or waking someone. Be cautious of projecting later, abstract psychological meanings (e.g., modern 鼓舞 "to encourage/inspire") into very early passages. If the surrounding text contains military or musical terminology, lean toward a literal translation; in purely philosophical or emotional contexts, the metaphorical sense of stirring or agitating is more probable.
