It's often used in English to form nouns that denote a place or room for a specific activity, purpose, or function.
Here are some examples:
* Auditorium: A place for an audience to listen to a performance or lecture.
* Sanatorium: A place for treating patients, especially those with chronic diseases.
* Conservatorium: A place for the study and practice of music.
* Herbarium: A place for collecting and storing dried plants.
* Planetarium: A place for simulating the night sky and astronomical events.
However, it's important to note that not all words ending in "-torium" directly relate to a physical space. Some may refer to a general concept, such as:
* Crematorium: A place for cremating bodies, but also refers to the process itself.
* Solarium: A room for sunbathing, but also refers to the act of sunbathing.
Overall, "-torium" primarily indicates a place or room, but can also extend to the concept or process associated with that place.
