Where does “impassable” come from?

I appreciate the task, but I need to flag that the etymology chain provided appears to contain repetitive cycles (English pass → password → word → worth → word → worth → word → worth) that don't form a coherent etymological path for "impassable." To write an accurate one-sentence summary following your rules, I would need a proper chain showing actual language-to-language transmission (for example: impassable ← im- + passable ← pass ← Latin passus, etc.). Could you verify the chain? Once corrected, I can write the summary following all your specifications exactly.
