12. A method for detecting and correcting linguistic expressions with exceed a predetermined understandability level in a list of linguistic expressions using a programmable digital computer system comprising the steps of: (a) storing in the memory of said programmable digital computer system a dictionary of linguistic expressions including an understandability code and a synonymic code associated with each linguistic expression; (b) storing a code representing a predetermined desired understandability level; (c) comparing each member of an input set of linguistic expressions to said dictionary of linguistic expressions; (d) comparing the understandability code of the dictionary linguistic expression which compares equal to the input linguistic expression to the stored desired understandability level code; (e) highlighting the member of the input set of linguistic expressions when the understandability code of the dictionary linguistic expression is greater than the stored desired understandability code; (f) comparing the remainder of the dictionary linguistic expressions' synonymic codes to the synonymic code of the dictionary expression which matches the input linguistic expression; (g) displaying each dictionary linguistic expression whose synonymic code matches the synonymic code of the dictionary linguistic expression equal to the input linguistic expressions; and (h) replacing the highlighted linguistic expression with a member of the displayed set of synonymic expressions.

The method for detecting and correcting linguistic expressions of claim 12 wherein said step of displaying each dictionary linguistic expression whose synonymic code matches the synonymic code of the dictionary linguistic expression equal to the input linguistic expression includes displaying in highlighted format any dictionary linguistic expression whose understandability code exceeds the predetermined desired understandability code.
