Speaking of non-standard participle use, here are three I think are probably disappearing:
- Run – being replaced by “ran,” as in “I had ran”
- Swum – being replaced by “swam,” as in “I had swam”
- Become – being replaced by “became,” as in “I had became”
I say this because I’ve had 18-year old students to whom “I had ran,” “I had swam,” and “I had became” sound correct. They miss run-swum-become questions on ACT English.
You can see what they’re doing. They’re “regularizing” the participle, which I think may be the way languages normally evolve (though I don’t know).

Run, swim, and become are different:
