learnings

This word is extremely uncomfortable to hear, just say teachings or lessons... From the wiktionary page linked: "from circa 2000 it became a buzzword in business speak, particularly in constructions such as “key learnings” or “apply these learnings”"

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.

unsatisfying

This word is very dissatisfying to hear
