筛

• 拼音: shāi
• 汉字拆解: 筛 = 竹 (bamboo radical, top) + 師 (phonetic shāi) = originally a round bamboo sieve used to separate grain by particle size

含义

To sieve or sift; to pass a substance through a mesh screen to separate particles by size. Also used figuratively for any filtering or winnowing process.

In cooking, 筛 is used for flour and powdered ingredients. In construction, it separates sand and gravel by particle size. Figuratively it describes preliminary filtering: 筛掉不合格的申请人 (weed out unqualified applicants). Often precedes 筛选 in a two-step selection process. 过筛 (to pass through a sieve) is the standard verb phrase.
