Regarding wreckless, I see this: There are no contexts in which its usage is correct.
I didn't read beyond that point but I'll go back later.
I would use wreckless to communicate the idea of without a wreck. For example: I felt relief that my 16 year-old son's drive to school was wreckless.
Maybe that's wrong, but it feel right to me.
Wreckless driving - driving without a wreck
Reckless driving - driving without regard for a wreck.
am I wrong?
