Other Issues

There is a lingering problem with the auxiliaries that stems from the fact that there currently is no way to distinguish between the main verb and auxiliary verb behaviors for a given letter string within the morphology. This situation results in many unacceptable sentences being successfully parsed by the system. Examples of the unacceptable sentences are given below.
