Most of the common irregularly formed verbs should already be in the lexicon. If you feel that some are missing, please contact the Cyc NL team.

Adding irregular verbs is similar to adding regular verbs, except that you must specify all syntactic forms. After specifying a word on the main "Add To Lexicon" page, choose the "Add irregular strings to lexicon" button and "Add Info". After a new word is created, or after entering an existing word, WALES will display the "Add Part of Speech Forms" page.

On this page, each part-of-speech form is followed by a series of boxes. For the verbs, there are five boxes which designate the infinitive, 3rd person singular, progressive, past tense, and perfect tense forms. Enter strings in their appropriate boxes.
