An '''input method''' (or '''input method editor''', commonly abbreviated '''IME''') is an [[operating system]] component or program that enables users to generate characters not natively available on their [[Inputinput device|input devices]]s by using sequences of characters (or mouse operations) that are available to them. Using an input method is usually necessary for languages that have more [[Grapheme|graphemesgrapheme]]s than there are keys on the keyboard.

For instance, on the computer, this allows the user of [[Latin alphabet|Latin]] [[Keyboard layout|keyboards]] to input [[Chinese characters|Chinese]], [[Japanese writing system|Japanese]], [[Hangul|Korean]] and [[Indic script|Indic]] characters. On hand-held devices, it enables the user to type on the [[Telephone keypad|numeric keypad]] to enter [[Latin alphabet|Latin alphabet characters]] (or any other alphabet characters) or touch a screen display to input text. On some operating systems, an input method is also used to define the behavior of the [[Deaddead key|dead keys]]s.

Although originally coined for [[CJK]] (Chinese, Japanese and Korean) computing, the term is now sometimes used generically to refer to a program to support the input of any language. To illustrate, in the [[X Window System]], the facility to allow the input of [[Latin character]]s with [[diacritic]]s is also called an input method.

===Input methods for handheld devices===

* {{anliannotated link|Multi-tap}} —Used on many mobile telephones—hit the (combined alphanumeric) key for the letter you want until it comes up, then wait or proceed with a different key.

*{{anliannotated link|T9 (predictive text)|T9}}/[[XT9]]—Type the key for every letter once, then, if needed, type Next until the right word comes up. May also correct misspellings and regional typos (if an adjacent key is pressed incorrectly).

*{{anliannotated link|iTap}} —Similar to first-generation T9, with word [[autocomplete]].

*{{anliannotated link|LetterWise}}—Hit the key with the letter you want, if it doesn't come up, hit Next until it does.

*{{anliannotated link|FITALY}} (An array, almost square, which minimizes distance travelled from one letter to another.)

*[[MessagEase]], an input method optimized for the most common letters, that can enter hundreds of characters with single hand motions

*[[8pen]], an input method using circular swipes in an attempt to mimic hand movements
