Here's why:
* Varied Cultures & Religions: Temples are a part of many different religions and cultures, each with their own distinct features and purposes. This makes it difficult to have a single term that encompasses all types of temples.
* Lack of Common Usage: Unlike words like "flock" for birds or "herd" for cattle, there hasn't been a consistent usage of a specific collective noun for temples in the English language.
Alternatives:
While a precise collective noun doesn't exist, you can use descriptive phrases to convey the idea of multiple temples:
* A complex of temples
* A sanctuary of temples
* A congregation of temples
* A collection of temples
You can also use more general terms like:
* A group of temples
* A cluster of temples
* A series of temples
The best choice will depend on the specific context and the kind of temples you're referring to.
