verb

To suppose that something is true before you have proof. It often means an idea is already taken for granted.

  • Her question presupposes that I know the answer.
  • The plan presupposes good weather.
  • This theory presupposes trust between both sides.

Adinary Nuance

Presuppose is close to assume, but it is more formal and often used in academic or careful writing. It suggests that one idea must already be true for another idea to make sense. Writers choose it when they want to show a hidden starting point, not just a simple guess.
