Procedure word

A procedure word is a special word that people use to communicate important information very quickly and clearly. It's kind of like a secret code that only certain people know how to use. Imagine you're playing a game with your friends and you need to tell them something really important, like "stop the game," but you don't want the other team to know what you're saying. You might use a special code word instead of saying "stop the game" out loud.

In the same way, procedure words are used in all kinds of situations to make sure everyone involved understands exactly what's happening. Pilots and air traffic controllers use them to communicate important information during flights, for example. Some common procedure words that they might use include "roger," which means "I have received your message and understand it," and "mayday," which means "we have an emergency and need help right away."

Another example of procedure words being used is during military operations, where they can help soldiers understand what actions they need to take. For example, the word "freeze" might mean "stop moving right now," while the word "fire" might mean "shoot at the enemy."

In summary, procedure words are special words that people use to make sure everyone involved understands important information quickly and clearly, kind of like a secret code. They're used in all kinds of situations, from games to flights to military operations.
