I heard it through the grapevine
Meaning
To learn information informally, often through rumor or unofficial channels rather than direct, official sources.
Origin
The phrase "through the grapevine" originated during the American Civil War, when improvised telegraph lines were strung haphazardly from tree to tree or pole to pole across battlefields. These tangled, often unreliable lines were quickly dubbed "grapevine telegraphs" by soldiers due to their resemblance to wild grapevines. Information transmitted over these rough-and-ready networks was frequently garbled, distorted, or simply rumor. Thus, hearing something "through the grapevine" became synonymous with receiving unverified, informal, and often suspect news. The imagery stuck, evolving from a literal description of faulty telegraphy into a universal metaphor for unofficial communication, cemented in popular culture by Marvin Gaye's legendary 1968 hit song.
Examples
- I heard it through the grapevine that the company is planning a major reorganization next quarter.
- The news about their engagement was only officially announced today, but I heard it through the grapevine last week.
