A typographical error, often called a "typo," occurs when a mistake is made in the typing process, resulting in incorrect spelling, punctuation, or formatting. These errors can happen due to various reasons, such as hitting the wrong key, overlooking a mistake, or using autocorrect features that change words unintentionally. Typos are common in written communication, including emails, texts, and printed materials. While typographical errors are usually minor, they can sometimes lead to misunderstandings or misinterpretations of the intended message. In professional settings, such as publishing or journalism, typos can affect credibility and the overall quality of the work. Therefore, proofreading and editing are essential steps to minimize these errors.
