What does no mean?
“No” is one of the most familiar and versatile words in English. Before a noun, it indicates absence, as in “no evidence” or “no chance,” and it can also mean “not any.” When used alone, it gives a negative answer, refuses an offer, denies a claim, or expresses surprise and opposition. Its force can be softened with “not” or strengthened by repetition, pitch, or emphatic punctuation. In formal and literary contexts, the noun “no” can refer to a refusal or a vote against something, while the older verb meaning “to prohibit or refuse” appears in official language. The word is nearly universal in English-speaking communities, and its brevity makes it especially effective in dialogue, headlines, and public announcements. Although “no” can be a simple response, its choice can carry subtle social implications, including disagreement, resistance, or the deliberate refusal of an alternative.
A word used before a noun to indicate that the noun does not exist, is absent, or is not available.
"The train left without any announcement and there was no explanation."
The determiner sense is especially common with abstract or countable nouns: “no time,” “no reason,” and “no alternative.”
A word used to make a statement negative, to deny an assertion, or to refuse permission or an offer.
"I said no to the proposal because it was too costly."
As an adverb, “no” is often emphatic when it stands alone or is repeated: “No, definitely not.”
An exclamation expressing surprise, disbelief, disappointment, or opposition.
"No! You cannot be serious about this."
This use is informal to neutral and is especially common in speech.
A refusal, denial, or negative vote.
"The proposal was rejected after the chairman answered no."
The noun is formal but established; the plural is “noes.”
The plural “noes” is used for individual refusals or negative votes, especially in formal contexts.
"The committee recorded several noes to the proposal."
From Old English “nā,” “no” became one of English’s most powerful words: a single syllable can deny existence, reject an offer, or stop a conversation in its tracks.

Where does no come from?
The word descends from Old English “nā,” a negative adverb and determiner that developed from the Proto-Germanic root *ne. It survives in English most strongly in “no,” while related forms include “none” and “nought.” The word has also been influenced in usage by the widespread English negative “not,” although “no” retains a distinct role in answers, absence, and emphatic denial.

“No” is pronounced like “know” in many accents, but “know” means to have information or understanding, whereas “no” expresses a negative answer or denial.
“No” and “now” differ in vowel sound: “no” has a long “o” sound, while “now” has a diphthong beginning with that sound.
