"Seed" does seem like a logical past tense for "see" - even though I cringe when I hear it.
The ones that I still have trouble with are "lie" and "lay" . "Lie" - as in an untruth, I get.
"Except and accept" - I've seen this more often than I wanted to: "I except PayPal"
"If you agree to this ___, you've excepted the terms and conditions ...."
And I still don't know where to put the second quotation mark(s?) -
