Anticipating the word being entered when only a few letters are typed, or anticipating the next word in the sentence. Predictive text differs from the autocomplete function in email programs and Web browsers. They only fill in known addresses that were previously used. Predictive text works with regular words and grammar.
It Can Really Predict - If You Let It
Predictive text applications may request access to a user's social media, email addresses and other proprietary information so they can better estimate more of the words a person uses every day. See autocomplete

Enormously helpful on tiny keyboards, predictive text saves many keystrokes. On this Android memo app, tapping "Tomato" completes the word and adds a blank space.
Far more sophisticated than completing words is completing sentences. These examples from the popular SwiftKey Android app (top) and the BlackBerry 10 smartphone (bottom) anticipate the next word the user wants to type. Inserting the text takes a single tap on SwiftKey or an upward swipe on the BlackBerry.
