A system, method and article of manufacture utilize word chunks to enhance word prediction. At least one of selectable words and word chunks are displayed in response to receipt of an input character. Thereafter, a selection of a displayed word or word chunk is received, and in response to receiving selection of a displayed word chunk, selectable words including the selected word chunk are displayed. A word chunk includes a word portion used in the formation of other words and includes a predetermined identifier, identifying it as a word chuck. Thus, the combination of chunking of parts of agglutinated words in combination with letter input activations reduces the overall number of input activations to complete a word, and further reduces the amount of choices to select from at any point during retrieval of the word. Accordingly, for such agglutinating languages such as German, for example, word chunks can be used to speed up word prediction and thereby eliminate unnecessary, time consuming, and sometimes difficult inputting of many individual characters.
