受益 literally means 'to receive benefit' — 受 (shòu) means 'to receive' or 'to undergo', and 益 (yì) means 'benefit' or 'advantage'. Together, they form a verb meaning 'to benefit' or 'to gain advantage', typically used in formal or written contexts. It is commonly followed by 于 (yú) to indicate the source of benefit, as in 受益于… ('benefit from…'). Unlike the more colloquial 得益 (dé yì), 受益 carries a slightly more serious, objective, or institutional tone — often seen in news reports, policy documents, education, or health-related discussions.

The word usually appears in passive or experiential constructions and rarely stands alone without context. It emphasizes the result of gaining something positive — knowledge, health improvements, economic gains, or social advantages — rather than the active process of seeking benefit. Because it's a two-character compound with clear semantic roles, learners can remember it by linking 受 to 'receiving' and 益 to 'good outcome' — like 'receiving good outcomes'.
