神采 (shén cǎi) is a compound noun meaning 'vitality' or 'lively sparkle', especially as seen in a person’s eyes, face, or overall bearing. The first character 神 (shén) means 'spirit', 'divinity', or 'essence', suggesting inner energy or life force; the second character 采 (cǎi) originally meant 'to gather' but here functions as a phonetic-semantic component conveying 'appearance', 'bearing', or 'demeanor'. Together, they evoke the visible manifestation of inner vitality—how someone's spirit shines outward through expression, posture, and presence.

This word is often used to describe people who appear energetic, confident, and animated—especially after rest, success, or emotional uplift. It appears frequently in literary, descriptive, and appreciative contexts: praising an elder’s youthful vigor, a performer’s stage presence, or a recovering patient’s renewed animation. While it can refer to physical appearance, it always implies an inner quality made perceptible—never merely superficial attractiveness.
