No

No is used to express refusal, disagreement, or the absence of something. You say “no” when you don’t want something, when something is not allowed, or when a statement is not true. It is one of the first words people learn because it is used in everyday communication. Though short, it communicates clear boundaries and decisions. Saying “no” can protect your time, safety, or feelings. It can be used in personal conversations, work situations, or any context where a person needs to stop or reject something. It can also mean “not at all” or “not in any way” (as an adverb), like they are no better than before. It is also used as a thing someone says, often after verbs like say, hear, accept. For example, learning to say no politely can help you avoid stress, protect your boundaries, and make decisions that support your health and well-being.
