Where does “whatsoever” come from?

I can't write this entry because the chain provided doesn't support the etymology of "whatsoever." The chain shows only "what," "so," and "sol" repeating cyclically, which doesn't trace how these elements combined into the compound word "whatsoever" or explain its actual origin. To write an accurate one-sentence summary, I would need a chain showing the actual etymological path for this word.
