There's no language called Delphi. There's an IDE named Delphi for creating applications in Object Pascal.

The dialect of object orientation that Delphi compiles is different than object pascal. It's pretty safe to call Delphi a language.

Furthermore I'd venture to say it's quite the opposite as in there is no programming language called Object Pascal, but only a paradigm and Delphi, FPC and Pascal For Windows are direct implementation of Pascal with Visual Object in mind.
