Base Claim:
1. A word-processing system having a memory, character and control input to the system through a keyboard with a set of alpha-numeric and function keys depressible by an operator, and a display normally presenting text currently entered by the operator; in combination with: a list of commonly-confused words stored within said memory, each word of a commonly-confused group in said list being followed by the definition thereof and at least one alternative word confusable therewith, said at least one alternative word being followed, in turn, by a discrete definition corresponding thereto; a detection element for sensing any word from said list of commonly-confused words entered into the system, a generator of a warning signal for the operator normally activated in response to said detection element sensing an entered word from said list; a first control responsive to pressing a given key of said set, said first control replacing said text in the display by the entered word from the list along with the definition thereof; a second control responsive to pressing a further key of said set subsequent to pressing said given key, said second control presenting in the display said alternative word and said discrete definition in place of the entered word and the definition thereof; a plurality of conditioning means interposed between the detection element and the generator, each of said plurality corresponding to a particular word in the list, including the entered word and the at least one alternative word confusable therewith, and each of said plurality being initially in a first state enabling activation of said generator by said detection element; and a third control operative to change the conditioning means corresponding to the entered word to a second state in response to pressing an other key of the set subsequent to pressing said given key, said second state disabling responsiveness of said generator to sensing of said entered word thereafter; and operative to change the conditioning means corresponding to the at least one alternative word into said second state independently in response to pressing said other key subsequent to pressing said further key for presenting said at least one alternative word and corresponding discrete definition in the display for consideration by the operator, said second state disabling responsiveness of said generator to sensing of the at least one alternative word thereafter, whereby alerting an operator as to entry thereafter of any word in a group of commonly-confused words may be selectively and independently disabled upon first detecting one of the group in said text.

Claim 5:
5. The word processing system of claim 1, wherein said detection element comprises a second list of properly-spelled words together with marker means therein, said marker means identifying discrete words of said second list as being duplicates of words in said list of commonly-confused words; and individual memory means comprising said conditioning means and being present in one-to-one correspondence with said discrete words, each said individual memory means normally being in said first state enabling generation of said warning signal and wherein said third control comprises address means associated with each of said discrete words of the second list, said address means locating the individual memory means for selective setting by said operator to said second state disabling generation of said warning signal.
