A method for enabling generation of text on a handheld electronic device which has a plurality of input members, at least some of which have a number of linguistic elements assigned thereto, and a memory having language objects stored therein. The method comprises enabling detection of a number of input member actuations corresponding with an ambiguous input, making at least one of a determination that the number of actuations exceeds a first threshold and a determination that a quantity of predicted language objects corresponding with the ambiguous input is less than a second threshold, generating prefix objects corresponding with the ambiguous input and predicted language objects corresponding with the ambiguous input, each predicted language object comprising a prefix object portion and a completion portion, and providing at a text input location an output comprising a prefix object and a completion portion of a first predicted language object.
