Well, and even machine language is effectively interpreted, namely by the systems processor.
In principle you have two processes. One is compilation. It means a program (or code) written in one language is transformed into an equivalent program in another language (or code). No execution of code takes place.
The other process is interpretation. It's when the actual execution of a program (or code) takes place. It could take place in software or hardware. And the hardware is often just an interface for other layers of software.
So compilation means transformation and interpretation means execution.
