粉碎 (fěn suì) is a compound verb meaning 'to crush' or 'to smash completely into tiny pieces.' The first character 粉 literally means 'powder' and implies reduction to fine particles; the second character 碎 means 'broken' or 'shattered.' Together, they emphasize total, irreversible destruction — not just breaking, but pulverizing. This word conveys intensity and finality, often used for physical objects (e.g., rocks, glass), abstract concepts (e.g., illusions, plans), or ideological forces (e.g., outdated ideas, enemy resistance).

It frequently appears in formal, literary, or political contexts — such as news reports, historical narratives, or speeches — where strong, decisive action is described. While it can be used literally (e.g., crushing ore in industry), its most common modern usage is metaphorical: to 'shatter' hopes, myths, or opposition. It is rarely used in casual daily speech for minor breakage (e.g., dropping a cup); for that, 碎了 or 打破 is more natural.
