In humans the vermiform appendix is a vestigial structure; it has lost much of its ancestral function. Vestigiality refers to genetically determined structures or attributes that have lost some or all of their ancestral function in a given species, but have been retained during the process of evolution.

This is an organ that served a purpose in the distant ancestor of an organism, but is not longer pertinent in the presently existing, recently evolved, organisms.
An example would be the muscles we have that can move our ears a bit. Since human ears cannot be re-orientated like some animals can (and presumably our long gone ancestors from million of years ago) then those muscle do not serve much purpose (except for mild entertainment).
Another example would be our tail bone.
