Hello all. My question is: would the word whatsoever be always acceptable instead of at all, or are there cases when the use of whatsoever would sound incorrect or just sound bad? I never use the word whatsoever, I prefer using at all. I'd never say "I haven't eaten whatsoever", I'd say "I haven't eaten at all". Is the sentence "I haven't eaten whatsoever" even correct?? I was just wondering.... Q2: Whatsoever could also be a rather archaic substitute of whatever, right?
