What characterizes a vacuous expression?

A vacuous expression is characterized by emptiness, which means that it lacks meaningful content or substance. In various contexts, this term describes communication or expressions that appear superficial, trivial, or devoid of significant insight or thought. When something is termed 'vacuous,' it suggests that while it may convey a form of expression, it fails to engage with deeper or more meaningful concepts.

Understanding the nature of vacuity helps clarify why the other descriptions do not apply. For instance, excitement and intelligence imply a positive engagement with thoughts and emotions, while depth denotes the presence of complexity or insightful layers in expression. All these characteristics stand in contrast to the notion of vacuity, which is fundamentally about a lack of meaningful content or significance.
