Using standard terms and everyday language demonstrates which of the Five C's of Communication?

Using standard terms and everyday language is primarily associated with clarity in communication. Clarity ensures that the message is easily understood by the audience, as it avoids jargon or overly complicated terminology that could confuse listeners. By employing straightforward language, you enhance the receiver's ability to grasp the intended message quickly and effectively.

In the context of communication, clarity is fundamental because it establishes a common understanding, which is crucial in situations like emergency response where clear communication can significantly impact safety and effectiveness. Other elements like conciseness, control, and confidence are important in their own right but when focusing specifically on choosing language that is easily understood, clarity is the key aspect being addressed.
