Distinguishing Between No & Not

No vs Not

No and Not are two words that are often confused in terms of their usage, and it is essential to understand the difference between them. No is mainly used as a determiner, but it can also function as an exclamation, adverb, and noun. In contrast, the primary use of not is as an adverb, although there are instances where not is used as a noun and an adjective. No has its origins in Old English nō, nā, while not comes from Old English as a contraction of the adverb nought.

What does Not mean?

Not is generally used to make a sentence negative, such as in the example “He was not very happy.” It can also be used to make a part of a sentence negative, as in “The students went on strike but not the teachers.” Additionally, there are phrases in the English language that use the word not, such as “Not at all” (meaning “definitely not”) and “Not a thing” (meaning “nothing at all”).

What does No mean?

As a determiner, no is used with a noun to mean “not any,” as in the sentence “No leaders got arrested,” which means “Not any leader was arrested.” Used in this way, no can convey the idea of “not a single” or “not any.” For example, “No spectator left the stadium” means “Not a single spectator left the stadium.” As a determiner, no can also be used with another determiner, as in the sentence “No target is impossible to achieve,” meaning “Every target is possible to achieve.” Sometimes, the determiner no is used with a gerund, such as in the expressions “No Smoking” and “No Parking.” Finally, since no is a determiner, it must be used before singular and plural nouns.
