Meaning
Persistent rumors or suspicions usually have some basis in truth.
It’s used to argue that repeated gossip or accusations, even without hard proof, are unlikely to have come from nowhere.
Origin
The underlying sentiment is old and widely attested in English: John Heywood’s 1562 proverb collection records “There is no fire without some smoke,” and related forms of the saying are traced back to the mid-15th century. The idea is sometimes vaguely credited to classical antiquity, and occasionally to the Roman writer Publilius Syrus (1st century BC), whose surviving “Sententiae” is a collection of moral maxims — but no verse specifically matching this proverb survives among his authenticated sayings, so that attribution should be treated as folk etymology rather than a documented fact. What’s well established is that the smoke-and-fire image has circulated as a proverb across European languages for centuries, each culture reaching for its own natural image to make the same point about suspicion and truth.
