Definition

A flaw is a weakness or imperfection that reduces the quality of something.

A flaw is a problem or imperfection in an object, a piece of work, or a plan that makes it less effective or less attractive. It can also be a weakness in someone’s character or behavior. A flaw may be small and fixable, or serious enough to change the overall result.

Examples

  • The report is persuasive overall, but one flaw in its logic undermines the final conclusion.
  • I admired the design, yet I noticed a minor flaw in the stitching along my jacket’s sleeve.
  • She acknowledged her flaw of impatience and worked on listening before responding.

Common mistake

Learners sometimes confuse "flaw" with "scratch" or "stain"; a flaw can be invisible and can also refer to weaknesses in plans or personality, not only surface marks.
