Designed to help in studying or dealing with foreign languages, Conjugator is a handy substitution for the fat grammar books. It is implemented as one "host" program with many language plug-ins, each of which provides the conjugation functionality for particular language.
It is important to know that most language plug-ins use rules and exceptions specific to the language to perform the conjugation. Because of that, they do not have clear way of identifying made-up verbs and will made up conjugations for them. Irregular verbs are usually taken into account.
