How is "yearning" best characterized?

"Yearning" is best characterized as a deep longing because it conveys an intense and often persistent desire for something that is usually perceived as difficult to attain. This emotional state goes beyond a superficial wish or a fleeting feeling; instead, it reflects a profound sense of need or want that can resonate deeply within an individual. The depth of yearning indicates not just a desire but an emotional weight and significance attached to what is being longed for, whether that be love, success, or a sense of belonging.

In contrast, the other descriptors do not fully capture the essence of yearning; fleeting emotions are temporary, superficial desires lack the intensity and depth, and a moment of joy relates to happiness rather than a longing for something more. Therefore, the characterization of yearning as a deep longing encapsulates its profound emotional impact.
