Here are some examples of how it's used:
* Unabridged dictionary: A dictionary that contains all the words and definitions, as opposed to an abridged dictionary which may only have a limited selection.
* Unabridged novel: The full, original version of a novel, not a shortened or adapted version.
* Unabridged audio recording: A recording of a book or other work that includes all the content without any parts being omitted.
The opposite of unabridged is abridged, which means shortened or condensed.
