To transform an affirmative sentence beginning with 'Everybody' into a negative sentence without altering its original meaning, a common method is to use phrases like 'There is no one but...' or 'There is nobody but...'.

Alternatively, one can also use 'There is no one who does not...' followed by the rest of the sentence. The goal of this transformation is to express the same idea in a negative structure.

In this particular sentence, 'Everybody appreciates this quality' means that all individuals have a positive regard for this quality. The transformed sentence 'There is no one but appreciates this quality' conveys the identical meaning, implying that there isn't a single person who does not appreciate it.

It is one of the best qualities.

= Very few qualities are so/as good as it.

Very few men are as happy as a simple man.

= A simple man is happier than most other men.
