lawful

Something is lawful when the law allows it. A protest is lawful if it follows the rules set by the city or country. A business is lawful if it operates in a way the law permits. You will often see this word in legal writing, formal English, and official situations. It usually points to actions, orders, or behavior that stay within the law.

The word lawful describes something that is allowed by law or done in a way that follows the law. It is very close in meaning to legal, and in many cases the two words can be used in similar ways. Still, lawful often sounds more formal and is especially common when people want to stress that an action, order, or process is within the law.

You might describe a police officer's actions as lawful if they stayed within legal limits during an arrest. A "lawful order" is an order that a person in authority has the right to give under the law. The word also appears in phrases like "lawful owner," "lawful authority," or "lawful means," where the focus is on permission under the law rather than on custom or personal opinion.

You will still find it often in legal documents, formal writing, and public discussion. For example, saying "the company operated a lawful business" means the business was run in a way the law allowed. You might also hear about "lawful interception" of communications, meaning surveillance carried out under legal rules.

So the core idea is simple: if something is lawful, the law allows it. The word often brings a formal tone and is useful when the speaker wants to highlight that something is within the law.
