see https://github.com/obophenotype/cell-ontology/issues/3237 for more discussion and link relevant to punning concept.

I recognize this is an OWL DL 2 spec concern, but am not sure whether owlready2 cannot cope with this.

a CL maintainer mentioned that protege and OWL api-based tools accommodate punning.

Still interested in this issue.  If it is out of scope please close.

Sorry for the delay :-(

Punning has never been supported by Owlready, and will probably never be. It is too complex to implement in Python as it conflicts with the Python model, and the semantics of punning is not very clear in OWL.

Thanks for clarification.
