The Chinese word **试用** (shìyòng) is a compound verb formed through a common grammatical structure where two meaningful characters combine to create a new, specific term. It follows a **verb-object relationship**: the first character **试** (shì) means "to test" or "to try," and it acts upon the second character **用** (yòng), which means "to use." Therefore, the literal and functional meaning is "to test-use" or "to try out," specifically referring to putting something (like a product) or someone (like an employee) through a trial period to evaluate its or their performance before making a final decision on adoption or permanent hire.
