whatsoever → whatsoever

People often split 'whatsoever' into 'what so ever' or hyphenate it. That looks unpolished and is incorrect.

Below: the correct one-word form, when to use it, and ready-to-copy fixes for work, school, and casual writing.

Quick answer

Write it as one word: 'whatsoever'. Do not split or hyphenate it. It intensifies negatives; use 'at all' for a softer, conversational tone.

'whatsoever' is one word, not three.
It usually follows negatives (no, none, nothing) or replaces 'at all' in emphatic contexts.
Choose 'at all' or a neutral rewrite if 'whatsoever' sounds too strong.

Core explanation: the spacing error and the fix

'Whatsoever' is a single adverb that intensifies negatives. Common wrong forms include 'what so ever', 'what-so-ever', and 'whatso ever'.

Fix: remove the spaces or hyphens so the parts become one word: whatsoever.

Incorrect: what so ever, what-so-ever, whatso ever
Correct: whatsoever

Wrong: I have no interest in politics what so ever.
Right: I have no interest in politics whatsoever.
Wrong: There is no proof what-so-ever the product failed.
Right: There is no proof whatsoever that the product failed.

Real usage and tone: when to use 'whatsoever' (and alternatives)

'Whatsoever' sounds emphatic and slightly formal - useful in reports, legal writing, or forceful statements: 'There is no evidence whatsoever.'

In casual speech or friendly email, 'at all' is usually more natural: 'I don't like it at all.'

Formal/emphatic: whatsoever (legal, academic, formal reports)
Casual/conversational: at all
Neutral rewrite: remove the intensifier or rephrase to avoid sounding overemphatic

Work: There is no evidence whatsoever supporting the claim.
Casual: I don't like it at all.
Neutral: I see no supporting evidence for the claim.

Hyphenation and spacing: why it's one word

Historically the parts fused into a single adverb. Modern standard English spells it as one word: 'whatsoever'. Hyphens or spaces are errors.

Typos often come from hearing separate syllables. Type it as one continuous word.

Correct: whatsoever
Incorrect: what so ever, what-so-ever, whatso ever

Wrong: I had no idea whatso ever about the meeting.
Right: I had no idea whatsoever about the meeting.

Grammar: how 'whatsoever' functions

'Whatsoever' typically follows negative determiners or pronouns: 'no evidence whatsoever', 'I have nothing whatsoever to add.'

Avoid stacked negatives: 'no nothing whatsoever' is wrong. 'Not whatsoever' is acceptable in the right context: 'I do not agree whatsoever.'

'no X whatsoever' (preferred pattern)
'I have nothing whatsoever (to add)'
Avoid redundancy that creates awkward double negatives

Usage: She had no doubt whatsoever about the plan.
Usage: I do not have any information whatsoever on that topic.
Wrong: I don't have no idea whatsoever. (double negative)
