What does pitfall mean?
A pitfall is a danger, complication, or mistake that is hidden, unexpected, or easily overlooked. In figurative use, the word commonly refers to problems that arise when planning, making decisions, managing a project, or operating a system. For example, inadequate preparation can be a pitfall, as can an unclear contract or a misunderstood instruction. The expression conveys not merely that something is dangerous, but that the danger may be concealed until it causes trouble. Its literal meaning, a hole or depression into which someone or something may fall, is still understandable but much less frequent in contemporary English. The word is useful when discussing risks, overlooked weaknesses, and preventable errors, particularly in formal, professional, and instructional writing.
