‘采用’ is a transitive verb meaning 'to adopt' or 'to employ'—typically referring to selecting and putting into practical use an idea, method, technology, policy, or solution. The first character 采 (cǎi) originally meant 'to gather' or 'to collect', suggesting the act of selecting from available options; the second character 用 (yòng) means 'to use' or 'to employ'. Together, they convey the full sense of 'selecting and then actively using something'. It’s commonly used in formal, written, or professional contexts—such as business reports, academic papers, government documents, or technical discussions—rather than casual speech.

This word emphasizes intentionality and implementation: it’s not just about considering an option, but about making it operational. It often appears with objects like 新技术 (new technology), 建议 (a suggestion), 方案 (a plan), or 方法 (a method). Unlike more colloquial alternatives like 用 (yòng) or 使用 (shǐ yòng), 采用 carries a nuance of careful evaluation before adoption, implying endorsement and integration into practice.
