Electronic dictionary with correct and incorrect words

An electronic dictionary comprising:

• digital memory, the digital memory storing:
• permanent word data including a first part of positive word data;
• and
• personal word data including a second part of positive word data, the personal word data further including negative word data;
• the first part of positive word data and the second part of positive word data together indicating a set of words, the first part of positive word data indicating a first subset of the set of words, the second part of positive word data indicating a second subset of the set of words;
• the negative word data indicating that a first one of the set of words is incorrect, the first word being one of the first subset of the set of words;
• and
• a processor connected for accessing the permanent word data and the personal word data stored in the digital memory to determine whether words are incorrect.

An electronic dictionary comprising:

• digital memory, the digital memory storing
• permanent word data including a first part of positive word data;
• and
• personal word data including a second part of positive word data and negative word data;
• the first part of positive word data, the second part of positive word data, and the negative data together indicating a set of words;
• the first part of positive word data indicating a first subset of the set of words, the first subset including a first word;
• the second part of positive word data and the negative word data together indicating a second subset of the set of words, the second subset also including the first word, the negative word data indicating that the first word is incorrect;
• and
• a processor for receiving data indicating the first word and connected for accessing the permanent word data and the personal word data in the digital memory to determine whether the first word is in the first and second subsets of the set of words;
• the processor determining that the first word is incorrect if the permanent word data indicates it is in the first subset of the set of words and the personal word data indicates it is in the second subset of the set of words.

An electronic dictionary comprising:

• digital memory, the digital memory storing:
• permanent word data including a first part of positive word data, and
• personal word data including a second part of positive word data and negative word data;
• the first part of positive word data, the second part of positive word data, and the negative word data together indicating a set of words;
• the first part of positive word data indicating a first subset of the set of words, the first subset including a first word;
• the second part of positive word data and the negative word data together indicating a second subset of the set of words that also includes the first word, the negative word data indicating that the first word is incorrect;
• and
• a processor connected for accessing the permanent word data and the personal word data stored in the digital memory to determine whether words are incorrect.

A method of operating an electronic dictionary that includes digital memory storing positive word data indicating a set of words, the positive word data including permanent word data indicating a first subset of the set of words and personal word data indicating a second subset of the set of words, the method comprising steps of:

• receiving character data indicating a first word from an operator;
• receiving a device signal from the operator indicating the operator's desire to delete the first word from the set of words indicated by the positive word data;
• and
• if the personal word data includes personal first word data indicating the first word, so that the first word is in the second subset, deleting the personal first word data from the personal word data;
• if the permanent word data includes permanent first word data indicating the first word, so that the first word is in the first subset, storing negative word data in the digital memory, the negative word data indicating that the first word indicated by the permanent first word data is incorrect.
