Levity is a feeling or quality that's lighthearted and humorous. It's when something brings a smile to your face.
You might hear someone say "I need some levity after this tough day" and they're asking for a break from seriousness, maybe watching a funny movie or reading a silly book. In other words, they want to shake off their worries and have some fun. Levity can be found in comedy, but it's not just jokes – it's also the carefree feeling that comes with being with people who make you laugh.
Lightness of manner or speech, frivolity; lack of appropriate seriousness; inclination to make a joke of serious matters.
