A thought, plan, or picture in your mind about something. It can be a suggestion or a way to do something.

  • That was a good idea.
  • She got the idea from a podcast.

Adinary Nuance

Idea is wider than plan and less complete than plan. An idea can be very early and vague; a plan usually has clear steps. It is also more neutral than thought, which often means a passing thing in your mind.
