Predictive Text

Predictive text is primarily designed to reduce the number of key strokes required to write a word or phrase. Typically, predictive text works on the principles of linguistics, and may also use a database of entries or terms the user has entered in the past.

Predictive text has gained some infamy for its frequent failure to choose the appropriate word in favor of something that's entirely inappropriate for the situation. Images of smartphone message strings that show hilarious predictive text failures have become a popular Internet meme.
