What does 'levity' refer to?

'Levity' refers to a lightness of manner, often characterized by a lack of seriousness or gravity. The term is commonly used to describe situations that are treated with a cheerful or flippant attitude, typically where somberness or weightiness might be expected. For instance, in a serious discussion, someone introducing humor or a playful comment might be said to inject levity into the conversation. This aspect of levity can serve to relieve tension or create a more relaxed atmosphere.

In contrast, the other options imply characteristics that are quite the opposite of levity. Seriousness of purpose suggests a focus on gravity and importance, which is fundamentally different from the carefree connotation of levity. Rigidity denotes inflexibility, which does not align with the lightness associated with levity. Weightiness refers to a substantial or serious quality, further emphasizing the stark difference between being weighty and being lighthearted. Each of these meanings underscores the essence of levity as a term of lightness and lack of seriousness.
