Abstract
A grammar learning aid is implemented with a processor and read only memory programmed in a manner that minimizes memory space and maximizes effective teaching. The programming is based on a unification grammar, in which sentences are determined by their features. The programming is implemented with logic programming in which predicates represent data, and in which logic variables permit features to be unified. This feature-based grammar approach permits an erroneous answer to be associated with a feature and that feature used to generate a similar device.
