Pos (attribute capturing the part of speech)

Replacing the isNoun, isVerb and productive attributes with a single attribute that captures the detailed part of speech (verb, stem noun, root noun, adjective, adverb). Also replace reflexVerb with reflexive, with three values (always/optionally/never) in order to be able to easily search for verbs and nouns with optional reflexive as well as those with compulsory reflexive.
