However, "-rium" is a common suffix that often indicates:
* A place or location:
* Aquarium: a place for fish
* Sanatorium: a place for healing
* Auditorium: a place for performances
* Planetarium: a place to simulate the night sky
* A collection or group:
* Herbarium: a collection of dried plants
* Museum: a collection of artifacts
* Bibliotheque: a collection of books
It's important to remember that "-rium" is a suffix, not a root word. It needs to be attached to a base word to have meaning.
