The free dictionary provides two definitions for "rich with" and "rich in".
- rich with: having a lot of something; abundant in something
- rich in: having valuable resources, characteristics, traditions, or history
It seems like the differences between the two definitions is rather subtle. My understanding is the following. The former case means that an object contains a lot of something (and we don't know anything about the quality of this something). The latter means that the object contains something which is valuable (and we don't know how many instances of this something our object contains).
Is this observation correct? Can someone clarify the difference and provide some further references?
The context of this questions is that I want to write something like "The literature is rich in/with examples".
