‘试用’ literally combines ‘试’ (to try, to test) and ‘用’ (to use), meaning to use something temporarily to evaluate its suitability or effectiveness before committing to full adoption. It implies a trial period — not just casual experimentation, but a purposeful, often formal or structured, assessment phase.

This term is commonly used in workplace contexts (e.g., probationary employment), software (free trial versions), consumer goods (test samples), and services (trial subscriptions). Unlike the more casual ‘试试’ (just ‘give it a try’), ‘试用’ carries connotations of evaluation, duration, and potential follow-up decision-making — such as continuing employment, purchasing, or upgrading. It can function as a verb (e.g., 试用这个软件) or a noun (e.g., 试用期 — probation period).
