采纳 (cǎi nà) is a formal, written verb meaning 'to adopt' or 'to accept and put into practice'—typically used for suggestions, proposals, plans, opinions, or recommendations. It combines two characters: 采 (cǎi), which originally meant 'to gather' or 'to select', and 纳 (nà), meaning 'to receive' or 'to take in'. Together, they convey the idea of actively selecting something valuable from many options and incorporating it into action or policy.

This word appears frequently in official documents, business meetings, academic discussions, and media reports—especially when describing institutional or leadership decisions. It carries a tone of careful consideration and authority; you wouldn’t use it for casual personal choices like picking a restaurant. While often translatable as 'adopt', note that it implies both acceptance *and* implementation—not just agreement. It’s commonly paired with nouns like 建议 (suggestion), 意见 (opinion), 方案 (plan), or 提案 (proposal), and usually follows a subject indicating who is doing the adopting (e.g., the government, a company, or a teacher).
