保护 (bǎo hù) is a compound verb meaning 'to protect' or 'to safeguard'. It combines two characters: 保 (bǎo), which means 'to keep safe' or 'to preserve', and 护 (hù), which means 'to guard' or 'to defend'. Together, they emphasize active, intentional effort to prevent harm or loss. This word is commonly used in contexts involving safety, conservation, rights, and welfare — especially for vulnerable people, animals, the environment, or cultural heritage.

It functions as a transitive verb and typically takes a direct object (e.g., 保护环境, 保护儿童). In formal writing and public discourse, it frequently appears in policy language, news reports, and advocacy slogans. While it can be used in everyday speech, it carries a slightly serious or responsible tone — you wouldn’t say 保护我的手机 to mean 'I’m guarding my phone'; instead, use 看着 or 守着 for casual situations. It’s also common in fixed phrases like 保护措施 (protective measures) and 保护法 (protection law).
