40. An apparatus, comprising: a processor, configured to receive an indication of initiation of a search, of a stored interactive dictionary database, by a user; and an integrated input and display device to display an electronic screen overlay including a plurality of polysemous symbols to the user, the electronic screen overlay further being usable for searching the interactive dictionary database, the processor being further configured to receive an indication of input of text into the electronic screen overlay usable for searching, and determine whether or not at least one entry in the interactive dictionary database includes a previously stored at least one word, sentence, phoneme, message, letter, number, morpheme, command and phrase matching the input text, and the display being further configured to display, upon the processor determining that one or more entries in the interactive dictionary database includes a term corresponding to the text of a previously stored at least one word, sentence, phoneme, message, letter, number, morpheme, command and/or phrase that matches the input text, a definition of the determined one or more identified entries in the interactive dictionary database, the definition including a sequence of symbols including at least one of the plurality of polysemous symbols of the electronic screen overlay, at least a subset of the plurality of polysemous symbol sequences being assignable by a user at least one of an active and an inactive status, wherein when an inactive status is assigned to one of the plurality of polysemous symbol sequences, a corresponding sequence of previously selectable symbols of the keyboard is rendered unselectable by the user.
