I feel like there should be a word for this, and it seems like it's on the tip of my tongue, but I just can't think of it.
Is there an adjective for when a number of things all originate from the same source?
I'll give you an example. Suppose you knew a number of jokes. You learned all of these jokes from the same person. All of these jokes could be said to be (adjective). Uni-source-ic?
Another example. You have a number of electronic devices. They all came from the Apple Store down the street. These devices are (adjective).
One final example. Suppose you believed that all knowledge in the world came from God. You would say something like "I believe in the (adjective) nature of all of the world's knowledge".
Can anyone help me out?
