We describe a verbalization of the logical content of OWL
ontologies — using OWL 1.1 without data-valued properties — in Attempto Controlled English (ACE). Because ACE is a subset of English,
the verbalization makes OWL ontologies accessible to people with no
training in formal methods. We conclude that OWL can be verbalized
in concise and understandable English provided that a certain naming
style is adopted for OWL individuals, classes, and properties.
