fact

/fækt/
IELTSAcademic
noun

something that is true and can be proved. It is not just a guess, opinion, or belief.

  • It is a fact that the Earth orbits the Sun.
  • Please check the facts before you share the story.
  • The report is based on facts, not rumours.

Adinary Nuance

A fact is something true and provable. Use fact when you want to stress evidence, not personal feeling. It is stronger and more exact than truth in everyday academic writing, because a fact can be checked. It is also different from opinion, which is a personal view.
