A typo, also called<em> misprint</em>, is short for typographical error. It makes reference to a mistake made in a written or published text when it was typed. A misspelled word or misplaced punctuation mark is a typo. For example, in the sentence "the essay the student wrote was about the role of women in <u>sceince</u>" contains a typo. The writer may have accidentally changed <em>science </em>for <em>sceince</em>.
