The database covers 111 languages, and concentrates on person syncretism. It documents instances where particular person and number combinations share the same form (for example, the English verb 'to be' where one form is used with you (sg), we, you (pl) and they: you are, we are, you are, they are). The database also records properties which might be conditioning factors for person/number syncretism: tense/aspect/mood, inflectional class, gender of subject, and syntactic context. Each instance of syncretism is hyperlinked to an illustrative paradigm.
