A method of inputting letters in a wireless terminal is disclosed. The method comprises steps of: typing in at least a first and last letter of a word to be input, and pressing a function key, recognizing as the last letter of the word to be input a letter typed-in prior to pressing the function key, retrieving from a word repository words having the same first and last letters as the typed-in first and last ones, and displaying the retrieved words on a display device, selecting a desired word from the displayed words, and converting the typed-in first and last
