Q. Which is the correct version: “a framework with which” or “a framework from which”? I’ve always heard the latter, but when I Googled this question, I found examples of both.
A. This is like asking which is correct, “I walked with” or “I walked from.” The idea is to use with or from to say what you want to say. A framework with which I struggled, a framework from which I took my ideas, a framework within which they manipulated the data, a framework at which I laughed. If it’s hard to decide which one you need, phrase it less formally: a framework I struggled with, a framework I took my ideas from, a framework they manipulated the data with, a framework I laughed at. (And don’t worry: it’s perfectly grammatical to end with a preposition!)
