From the wikipedia article: "Borland used the name Object Pascal for the programming language in the first versions of Delphi, but later renamed it to the Delphi programming language. However, compilers that claim to be compatible with Object Pascal are often trying to be compatible with Delphi source code.[citation needed] Because Delphi is trademarked, compatible compilers continued using the name Object Pascal" You're still right that Object Pascal can encompass more than just Delphi.
