hearsay, n.All

Hearsay is not always bad — in the case of mushrooms and toadstools, it's better.

Hearsay is what toddlers do when anyone mutters a dirty word.

Hearsay is like laughing at a joke not because one has understood it but because someone else said that it was funny.

Hearsay is information acquired from another party that is sufficiently robust to be relied on by newspapers, households and workplaces, but not by a court of law.

Hearsay is worthless in a court of law. You can't so much as get a parking ticket on hearsay evidence.
