Abstract
In a grammar checking system which includes first tagging a sentence as to parts of speech and recovery of underlying spellings, a system for the correction of inflections includes identifying typical example of words which do not follow normal rules either as to pluralization, past tense, past participle, comparative formation and superlative formation, with this unique list of incorrect words forming the basis for suggesting suitable replacement words the system first performs a conventional spell check to detect mispellings by dictionary lookup system. Thereafter correct words are suggested based on an English dictionary and on the root forms and the morphological features derived from the incorrect words in the compendium.
