test
🔍 检 (inspect) + 验 (verify) = test and examine
检 means to check or inspect; 验 means to verify or prove. Together they form 检验, the act of testing something to confirm it meets a standard. Common in lab work, quality control, and customs inspections.
验 — horse radical 马 + 佥 (all/together)
A semantic-phonetic compound. The horse radical 马 originally referred to inspecting horses, while 佥 (qiān, 'all together') supplied the sound. Over time the meaning broadened from 'examine a horse' to 'test, examine, verify' in general.
