You use whatsoever after a noun group in order to emphasize a negative statement. My school did nothing whatsoever in the way of athletics. I don’t think they’ll have any idea how I’m feeling. None whatsoever.
Is it rude to use whatsoever?
2 Answers. Yes, it’s rude. “Whatever” expresses indifference; often, expressing indifference is dismissive, and in this case, it’s dismissive of what the other person has to say.
Which is correct whatever or whatsoever?
“Whatever” is used as a noun equivalent to “no matter what”. It’s an important part of the sentence and cannot be deleted. “Whatsoever” is used as an adverb with sentences with negative meanings.
