Matthias Passer’s research focuses on nominal classification systems. These are used as a grammatical device for categorising nouns and their referents with respect to their semantic characteristics, stem-forming morphemes or phonological shape. A common hypothesis states that one type of nominal system, known as a classifier system may undergo grammaticalisation and turn into a concordial class system. As this process has not been documented in any real world languages, Passer studies a sample of forty languages to investigate how likely this phenomenon is to occur.
