Typo
Last reviewed: 2026-06-21
A typo — short for "typographical error" — is a small mistake in typed or printed text that was made by accident rather than from not knowing the correct spelling or grammar. It includes mistyped letters ("teh" for "the"), transposed characters, doubled or dropped words, and stray or missing spaces.
What a typo is
A typo is a slip of the fingers, not a gap in knowledge. The writer knows the correct form; the keyboard, the autocorrect, or a moment of inattention produced the wrong one. Common shapes include transposed letters ("from" typed as "form", "the" as "teh"), a doubled word ("the the", "to to"), a dropped word, an extra or missing space, a wrong-but-adjacent key, and a letter left uncapitalized. The word is short for "typographical error", a term that originally described mistakes introduced during typesetting.
The important distinction is between a typo and a misspelling. A misspelling reflects not knowing the correct spelling; a typo is an accidental slip in producing text the writer could spell correctly. In practice the line blurs, and both are usually grouped together as spelling errors — what matters for catching them is whether the result is a non-word a dictionary rejects ("recieve", "teh") or a real word that is simply the wrong one ("from" for "form"), because only the first kind shows up in a spell check.
Why it matters for website copy
A typo on a live page is small but disproportionately costly: it signals carelessness on exactly the surface — a headline, a price, a call to action — where a visitor is deciding whether to trust you. And the web is unusually good at preserving typos, because copy is written once and revisited rarely. The typo on the fortieth page, in a footer, or in a templated product description survives every casual re-read of the home page.
Many typos are caught by a spell checker because they produce a non-word. The dangerous ones are the typos that land on a real word — "from" for "form", "now" for "not", "pubic" for "public" — which a dictionary check passes without complaint because the result is correctly spelled, just wrong. Verant checks spelling as one of its six kinds of copy issue — alongside grammar, punctuation, style, clarity, and placeholder text — across every page a visitor can load, and reads the copy for meaning rather than only matching a dictionary, so a real-word typo has a chance of being caught where a plain spell check would pass it.
Common mistakes
The most common mistake is trusting a single spell-check to find every typo: it flags non-words but passes the real-word slips that are often the most embarrassing. Another is proofreading only the pages you remember — typos cluster on the long-tail pages nobody re-reads. A third is re-reading your own copy too soon after writing it, when your eye fills in what you meant rather than what is on the page; a fresh read, or a second reader, catches far more.

Frequently asked questions
What is the difference between a typo and a misspelling?
A typo is an accidental slip — a mistyped, transposed, doubled, or dropped character or word — made by someone who knows the correct form. A misspelling reflects not knowing the correct spelling. In practice both are grouped as spelling errors; the practical difference is whether the result is a non-word a spell checker flags, or a real word it passes.
Why do spell checkers miss some typos?
Because some typos land on a real, correctly spelled word — "from" for "form", "now" for "not", "pubic" for "public". A dictionary check sees a valid word and passes it. Only reading the copy for meaning, not just matching a dictionary, catches a real-word typo.
