Final answer:
A message conveyed without words utilizes nonverbal communication, involving body language, facial expressions, and gestures which differ across cultures and supplement verbal communication.
Step-by-step explanation:
A message that is conveyed through something other than words uses nonverbal communication. This includes a variety of signals, gestures, and behaviors that do not involve verbal language. Nonverbal communication can be vital in creating positive impressions and can involve body language, facial expressions, gestures, and other forms of expression that do not rely on words. Examples of nonverbal communication include a smile, a wave, or a thumbs-up, all of which carry different meanings across various cultures. In the workplace, nonverbal communication is essential to supplement verbal interactions, helping to convey additional meaning or reinforce spoken words.
