A predictive text system and method are provided for use with a mobile device having a reduced-key QWERTY keyboard, a display, and an alert mechanism. The system includes an ambiguous word list and a predictive text system software module. The ambiguous word list comprises a plurality of keystroke combinations, each keystroke combination representing a plurality of key selections on the reduced-key QWERTY keyboard, wherein the keystroke combinations present in the ambiguous word list are associated with more than one common predicted word. The predictive text system module receives an input keystroke combination from the reduced-key QWERTY keyboard and determines a predicted word for the input keystroke combination, wherein the predicted word is displayed on the display of the mobile device. If the input keystroke combination is present in the ambiguous word list, then the predictive text system module engages the alert mechanism on the mobile device.
