Abstract
A hand held electronic spelling dictionary to facilitate the selection of a random word. A random word may be selected for purposes of playing games. An input word size is selected by the user through a keyboard. A random number generator generates a random number for each position in the word selected. The random number selects a letter from a predetermined letter table which table has a distribution of letters approximately equal to the frequency with which letters occur in the English language. The result is a selected letter sequence having a size equal to the input size from the keyboard. This is treated as an input word which is alphabetically traversed against the memory to find valid words of equal size. To minimize biasing the valid words selected, a second random number generator generates a second random number N to select as the output word, the Nth valid word found on an alphabetical traverse.
