Abstract: A symbol input method performed by a symbol input device having a display unit, a selector, and a determiner includes: displaying, by the display unit, a correspondence table indicating correspondences between input target symbols and selection target symbols and indicating that each of the input target symbols corresponds to one or more selection target symbols; ending the displaying by the display unit; prompting, by the selector, after the ending, a user to select one of the selection target symbols included in the displayed correspondence table; and determining, by the determiner, one input target symbol as a symbol to be input. The input target symbol is indicated in the displayed correspondence table and corresponds to the selection target symbol selected by the user in the prompting.
