‘加强’ is a transitive verb meaning ‘to strengthen’, ‘to reinforce’, or ‘to intensify’. It combines the character 加 (jiā), meaning ‘to add’ or ‘to increase’, and 强 (qiáng), meaning ‘strong’ or ‘powerful’. Together, they convey the idea of making something stronger, more effective, or more robust by adding support, effort, resources, or emphasis. It is commonly used in formal, written, and official contexts — such as policy documents, health advice, education, or workplace communication — rather than casual speech.

The word typically takes a direct object (e.g., 加强锻炼, 加强管理, 加强合作) and often appears with nouns indicating systems, relationships, abilities, or conditions. It implies intentional, active effort toward improvement or consolidation, not passive change. While it can describe physical strengthening (e.g., muscles), its most frequent uses relate to abstract domains: institutions, policies, skills, awareness, or organizational capacity.
