A '''typographical error''' (often shortened to '''typo'''), also called a '''misprint''', is a mistake (such as a spelling or [[transposition error]]) made in the [[typing]] of printed or electronic material.<ref>{{cite web | title=Typo - Definition | url=http://www.merriam-webster.com/dictionary/typo | publisher=Merriam-Webster | work=[[Webster's Dictionary|Free Merriam-Webster Dictionary]] | access-date=2012-01-03 | archive-date=2013-07-19 | archive-url=https://web.archive.org/web/20130719024138/http://www.merriam-webster.com/dictionary/typo | url-status=live }}</ref> Historically, this referred to mistakes in manual [[typesetting]]. Technically, the term includes errors due to mechanical failure or slips of the hand or finger,<ref>{{cite web | url=http://wordnetweb.princeton.edu/perl/webwn?s=Typographical+error&sub=Search+WordNet&o2=&o0=1&o7=&o5=&o1=1&o6=&o4=&o3=&h= | title=Wordnet definition | publisher=[[Princeton University]] | work=[[Wordnet]] | access-date=2007-11-12 | archive-date=2016-03-04 | archive-url=https://web.archive.org/web/20160304222243/http://wordnetweb.princeton.edu/perl/webwn?s=Typographical+error&sub=Search+WordNet&o2=&o0=1&o7=&o5=&o1=1&o6=&o4=&o3=&h= | url-status=live }}</ref> but excludes ''errors of ignorance'', such as [[Orthography|spelling errors]], or changing and misuse of words such as "than" and "then". Before the arrival of [[printing]], the '''copyist's mistake''' or '''scribal error''' was the equivalent for [[manuscript]]s. Most typos involve simple duplication, omission, transposition, or substitution of a small number of characters.

[[Fat-finger error|"Fat finger" typing]] (especially in the financial sector) is a [[slang]] term referring to an unwanted secondary action when typing. When a finger is bigger than the touch zone, with [[touchscreen]]s or [[keyboard (computing)|keyboard]]s, there can be inaccuracy and one may hit two keys in a single keystroke. An example is ''[[wikt:buckled|buckled]]'' instead of ''[[wikt:bucked|bucked]]'', due to the "L" key being next to the "K" key on the [[QWERTY|QWERTY keyboard]], the [[Keyboard layout#QWERTY|most common keyboard]] for [[Latin-script alphabet]]s.
