符合 is a verb meaning 'to conform to', 'to match', or 'to be consistent with' something — typically a standard, requirement, expectation, rule, or condition. The character 符 (fú) originally meant 'tally' or 'token', implying correspondence or agreement; 合 (hé) means 'to join', 'to fit together', or 'to be in harmony'. Together, they convey the idea of two things aligning precisely — like pieces fitting together perfectly. It’s commonly used in formal, written, or professional contexts: regulations, test results, specifications, logical reasoning, or subjective judgments about appropriateness.

This word emphasizes objective compatibility rather than personal preference. It often appears after a subject and before a noun phrase introduced by 的 or a clause introduced by 与…一致 or 于. While it can describe physical resemblance (e.g., matching a description), its core function is verifying alignment with an external benchmark — not just similarity, but correctness or validity according to criteria.
