Bad words
learnings
This word is extremely uncomfortable to hear, just say teachings...
orientated
This word sounds clumsy with the extra syllable, I think oriented means the same thing and sounds much more natural
gotten
I don't like most American words/spelling but I can get over them however this one tends to tick me off for some reason. It's weird because I'm okay with forgot and forgotten but not with got and gotten.
