I'm very thankful for Simple English Wikipedia for this reason. Compare the vanilla Set page https://en.wikipedia.org/wiki/Set_(mathematics) https://en.wikipedia.org/wiki/Set_(mathematics) with https://simple.wikipedia.org/wiki/Set https://simple.wikipedia.org/wiki/Set. It's too bad there aren't more of these pages, as they are honestly excellent quick resources.
