鉴于 (in light of)

• Pinyin: jiànyú
• Formation: 鉴于 + Observation / Situation，Conclusion / Suggestion
• Hanzi breakdown: 鉴 = 监 (supervise/mirror) + 金 (metal); 于 = a preposition character

Meaning

鉴于 (jiànyú) means 'in light of,' 'in view of,' or 'considering.' It introduces a known fact or observation that serves as the basis for a conclusion, decision, or suggestion.

鉴于 is a formal conjunction used primarily in written Chinese, official documents, reports, and formal speeches. It sets up a cause-and-effect structure where the clause after 鉴于 presents the factual basis, and the main clause presents the resulting action or judgment. Unlike 由于 which simply states a cause, 鉴于 implies careful deliberation before reaching a conclusion. It is commonly seen in government notices, academic papers, and business communications. In everyday speech, 考虑到 is often preferred as a less formal alternative. 鉴于 always appears at the beginning of a sentence or clause, never mid-sentence like 因为 sometimes can.

Examples

1. 鉴于目前的经济形势，公司决定暂缓扩张计划。 In light of the current economic situation, the company has decided to postpone its expansion plan.
2. 鉴于他在项目中的突出贡献，董事会一致同意给予表彰。 In light of his outstanding contributions to the project, the board unanimously agreed to commend him.
3. 鉴于天气条件恶劣，组委会宣布比赛延期举行。 In light of the severe weather conditions, the organizing committee announced that the competition would be postponed.
