There are many words in english that end with the suffix "-nym" or "-nymy". This comes from the ancient Greek ὄνυμα, meaning "name" or "word", and could even be loosely translated as "state of being".
A categorization of onomastic terminology is a helpful step in understanding data. In the automated creation of a semantic model, it is neccessary to develop patterns. Semantic models are primarily composed of space (static information) and time (process / event oriented). Patterns built around onoma help is deriving the former.
This is not a complete list of all Onoma. In many respects, the class of words ending with "-nym" could be considered open. Neologism (the type of words belonging to the class "neonym") can be easily created to describe any category for any entity type.
