Homonym: superficial (Shallow)
The term "superficial" refers to something that is concerned only with surface-level details rather than deeper significance or meaning. For example, a superficial understanding of a topic like climate change might involve only knowing its basic facts without grasping the underlying causes or consequences.
In everyday language, calling someone superficial often implies that they focus too much on appearances or material aspects, such as fashion or wealth, rather than on character or substance. This can suggest a lack of depth in their thoughts or relationships, emphasizing a preference for what is easily visible over what is more profound.
