This verb describes becoming aware of a fact or understanding it.

The idea

Use realize or realise with a noun, a clause with optional that, or a question word such as why. Both spellings are correct; realize is standard in American English and both occur in British English.

Examples

  • I realized that the shop was closed.
  • She realised her mistake after lunch.
  • We realized how far the station was.
  • He suddenly realised why the light was on.
  • They realized the plan needed more time.
  • I realise now that the answer is simple.
