erratio

So university session has started, giving me millions of papers that need to be read in advance and lots of interesting lecturers to listen to. And I noticed a strange trend which I didn't notice previously, namely this tendency to express adjectives that used to end in '-ic', like dynamic and problematic, with an '-al' suffix tacked on. So the AI lecturer has been telling us about dynamical systems, and just as I was thinking that I could float it past one of my linguistics lecturers I noticed that in the textbook about grammar, co-written by them and set as the prescribed text for one of my courses, features the construction 'unproblematical'. Am I the only one who finds the construction odd-sounding and unnecessary? Not that it matters of course since it looks like it's the new accepted way to write and say them.
