碎片 (suì piàn) literally combines 碎 (‘broken, shattered’) and 片 (‘flat piece, slice’), yielding the core meaning ‘fragment’ or ‘shard’ — a small, detached part of something originally whole. It refers to physical pieces resulting from breaking, cracking, or disintegration, such as broken glass, cracked pottery, or splintered wood. While often used for inanimate objects, it can also describe biological fragments — for example, bone fragments after injury or tissue fragments in medical contexts.

The term carries a neutral-to-negative connotation, implying loss of integrity or damage. It is commonly used in everyday speech, news reports (e.g., accident scenes), science (e.g., geological or forensic analysis), and even metaphorically (e.g., ‘碎片化信息’ — ‘fragmented information’). Unlike more general terms like 部分 (bù fèn, ‘part’), 碎片 emphasizes irregularity, small size, and accidental separation rather than intentional division.
