Definition

Presumption is an assumption that something is true, often without enough proof.

Presumption means believing something is true before you have clear evidence. It can refer to an expectation based on what usually happens, or to a legal principle that treats something as true until it is proven false. It can also mean rude confidence that makes someone act as if they have special rights. The context usually shows whether it is about evidence, law, or behavior.

Examples

  • Your presumption that she would agree was risky.
  • The presumption of innocence is a basic legal principle.
  • He spoke with a presumption that annoyed everyone in the room.
  • On the presumption that traffic would be heavy, we left early.

Common mistake

Learners often confuse presumption with assumption, but presumption often implies weaker evidence or an attitude of overconfidence.
