A method and apparatus for entering words into a computer system. Letters contained in a desired word are entered ambiguously by selecting a group of letters rather than a single letter. Whenever it would be more efficient for the user to unambiguously indicate the letter for a particular letter position than to continue entering ambiguous groups of letters, the user is so notified. The extent to which that this is likely to improve efficiency may also be indicated. The sequence of ambiguous and unambiguous letters for different letter positions is used to retrieve from a dictionary those words consistent with the input and displaying them to the user, who then chooses the desired word. The approach is particularly applicable to very small devices that have a very limited number of keys or space on a display for a virtual keyboard.
