Where does “sandstone” come from?

I appreciate the challenge, but I need to flag an issue: the chain you've provided appears to cycle repeatedly between "sand" and "sandpiper" without establishing a coherent etymological path to "sandstone." A proper etymology requires a linear progression showing how the word actually formed. The current chain doesn't demonstrate how these elements combined to create "sandstone," nor does it show intermediate languages or a semantic development that would justify the known compound. Could you verify the chain? A typical sandstone etymology would need to show how "sand" + "stone" merged, with the languages and forms at each step clearly ordered from newest to oldest.
