Several of those listed in the Vocabulary section of the OP.

* assist (to mean attend)

* "How is it called?"

* possibility (to mean opportunity)

* actual (to mean current)

I speak a few other European languages with some proficiency so I'm aware of the reasons for some of these changes. However, there's no reason for the quotes around "incorrect" if you take my quote out of context. I specified that they would be considered incorrect by these native English speakers (if the intended meaning is what is listed here), if not just grammatically incorrect. I'm not claiming that there exists inherently correct or incorrect grammar.
