An apparatus and method for inputting characters in which one of a plurality of characters can be chosen operate by using directional keys. The plurality of characters are classified into a predetermined number of groups and the directional keys are respectively allocated to the groups. Accordingly, when a user presses one of the directional keys, the characters belonging to the group to which the directional key pressed by the user is allocated can be sequentially chosen by sequentially pressing the directional key.
