Naught is not Not

The word "naught" literally means "nothing", "zero", or, "nonexistent" as in, "The boy knew naught of love or romance," or "Your work was all for naught," meaning that he knows nothing about those subjects and that your work amounted to nothing or zilch. The word "not", on the other hand, is used in the negation of a verb, in other words, to make the verb into the antonym of that verb, as in, "I know not how to eat raw oysters." Another way to say this is, "I don't know how to eat raw oysters," which means that I lack the know-how to eat raw oysters.
Contrary to what is believed by some, you may not randomly replace "not" with "naught" if it happens to follow the verb instead of preceding it. People who do this know naught of the English rules of grammar, which is similar, but not the same as saying that they Don't know the rules of English grammar. If you happen to find yourself in a situation where you know not whether to use "naught" or "not", you need only to give me a holler.
