媒合 (méi hé) is a verb meaning 'to mediate' or 'to facilitate an agreement or connection between two or more parties.' The character 媒 (méi) originally means 'matchmaker' — someone who brings people together, especially in marriage contexts — while 合 (hé) means 'to join,' 'to unite,' or 'to harmonize.' Together, they convey the idea of actively bridging differences, smoothing negotiations, or helping parties reach mutual understanding. It’s commonly used in business, diplomacy, community work, and personal relationships — for example, when a third party helps resolve disputes or arranges cooperation.

Unlike general terms like 帮助 (help), 媒合 emphasizes intentional, neutral facilitation with the goal of alignment or agreement. It carries a formal, constructive tone and often implies structured effort — such as organizing discussions, clarifying interests, or proposing compromises. While historically linked to matchmaking, modern usage extends broadly to any mediated coordination, from corporate partnerships to neighborhood conflict resolution.
