Which word refers to lightness and a lack of seriousness?

The term "levity" effectively captures the essence of lightness and a lack of seriousness. It is often used to describe a carefree or light-hearted attitude, particularly in situations where seriousness is typically expected. For example, one might display levity during a serious discussion to lighten the mood or to introduce humor. This quality can be beneficial in social contexts, allowing individuals to navigate tense situations more easily or to connect with others on a more playful level.

The other choices refer to different concepts: "gravitas" denotes seriousness or solemnity, "severity" implies harshness or strictness, and "formality" suggests adherence to established procedures or protocols, often associated with seriousness and structure. Each of these terms contrasts with the concept of levity, reinforcing that levity specifically embodies a lightness and a playful disregard for gravity.
