Words can change how a person feels about an everyday object or experience by the adjectives describing it. For example, if you were looking at your toothbrush and someone described it as "bright, clean, and sturdy," all of those adjectives have positive connotations with them. However, if that same toothbrush was described as "wet, inflexible, and covered in toothpaste residue," the emotions surrounding that very same toothbrush have now shifted to something more negative.
