Usage

What is a typographical error? A typographical error is a mistake made when typing something. Typographical errors are very commonly called typos for short.The term typically refers to an unintentional error that happens when you accidentally hit the wrong key on a keyboard—the kind of mistake that autocorrect is supposed to catch and automatically fix when you’re typing a document or texting. For example, typing teh when you mean to type the is a common typographical error.Typographical errors often result in misspellings, but, technically, not all misspellings are typos. It wouldn’t be quite accurate to call a misspelling a typographical error if you spelled the word that way on purpose. Still, people often use the word this way, especially when politely pointing out misspellings in things that other people have typed.The term typographical error can also refer to an error made during the printing process, such as due to a mechanical issue, but this sense of the term is much less commonly usedExample: I should have proofread my proposal because as I was presenting it I noticed a typographical error right on the title slide.
