Etymology
Adverb
not (not comparable)
Negates the meaning of the modified verb.
To no degree.
(understatement, litotes) Used to modify superlatives to indicate the opposite or near opposite, often in a form of understatement.
Usage notes
In modern usage, do-support requires that the form do not ... (or donât ...) be preferred to ... not for all but a short list of verbs (be, have, can, shall, will, would, may, must, need, ought)
• They do not sow. (modern) vs. They sow not. (KJB)
American usage tends to prefer donât have or havenât got to have not or havenât, except when have is used as an auxiliary (or in the idiom have-not)
• I donât have a clue or I havenât got a clue. (US)
• I havenât a clue or I havenât got a clue. (outside US)
• I havenât been to Spain. (universal)
The verb need is only directly negated when used as an auxiliary, and even this usage is rare, especially in the US.
• You donât need to trouble yourself. (common)
• You neednât trouble yourself. (outside US, rare)
• I donât need any eggs today. (universal)
The verb dare can sometimes be directly negated.
• I daren't do that.
The verb do, as a main verb, takes do not.
• He does not do that.
In the imperative, all verbs, including be, take do not.
• Don't do that.
• Don't be silly. (not *Be not silly.)
In the infinitive, verbs must be negated directly. In this case not cannot appear after the verb; some authorities recommend placing it before to to avoid a split infinitive, but for most speakers the forms not to do and to not do are more or less interchangeable, with the latter being mostly informal.
• The objective is not to lose or The objective is to not lose.
• I wanted not to go or I wanted to not go. (Note the difference between this and I didn't want to go, where want is the verb being negated.)
Conjunction
not
And not.
Usage notes
• The construction âA, not Bâ is synonymous with the constructions âA, and not Bâ; ânot B, but Aâ; and ânot B, but rather Aâ.

not!
(slang, 1990s) Used to indicate that the previous phrase was meant sarcastically or ironically.
