"offal" + "awful" (+ "awesome")

it looks like "offal" (trash) and "awful" (bad) could share a common forefather, but no:

offal

• Old English of- ("off") + feallan ("fall"), i.e. that which "falls off"
  • Old Norse affall [af ("from") + fall ("fall")], cognate with:
    • Swedish avfall
    • Danish affald
    • German Abfall
    • Dutch afval

awful

• Middle English awfull or awe-ful [awe ("feeling of fear") + ful ("full")]
  • borrowed from Old Norse agi ("terror")
    • Proto-Germanic *agaz ("terror")
      • PIE *h2egh ("fear")

thus, the word "awe" has to do with "fear" but today, with "awful", it's not fear, but "disgust"! So, what is "awesome"?

• well, from the same source: "awe" means "a feeling of fear"
  • …but it can also mean a "feeling of wonder"
    • …as things that once gave a sense of wonder, were also feared!
