If something is faster than the speed of sound, it's supersonic. And slower is subsonic. If something is the same as the speed of sound, is it just considered "sonic"?

There isn't really a sharp dividing line between subsonic and supersonic flight. As an object approaches supersonic speeds, local airflow can exceed the speed of sound as it is forced to go around an object, even before the object itself exceeds the speed of sound. This speed range is generally described as transonic.
