9. A computing device comprising: a display; at least one processor; and at least one module operable by the at least one processor to: display, at the display, a plurality of alphabet characters; receive an indication of a first gesture that selects a first set of alphabet characters from the plurality of alphabet characters, wherein the first gesture does not select the spacebar; determine, based at least in part on the first set of alphabet characters, a first candidate string; display the first candidate string; and after receiving the indication of the first gesture, after displaying the first candidate string, and prior to receiving any indications of gestures that select the spacebar, receive an indication of a second gesture that selects a second set of alphabet characters from the plurality of alphabet characters, wherein the second gesture is disjoint from the first gesture and does not select the spacebar; determine whether the second set of alphabet characters is included in the first candidate string; responsive to determining that the second set of alphabet characters is included in the first candidate string, continue the display of the first candidate string; and responsive to determining that the second set of alphabet characters is not included in the first candidate string: determine a second candidate string that includes the second set of alphabet characters; and display, at the display, the second candidate string and one or more space characters that separate the first candidate string from the second candidate string.

The computing device of claim 9 , wherein the first set of alphabet characters comprises a portion of the first candidate word.
