Can anybody tell me the adjectival form of levity? I've found levitious here, but not sure whether it’s a dictionary word.
Because levity means “lightness” and ultimately derives from Latin levis meaning “light”, the best adjective that corresponds to it is probably just plain light.
A conversation full of levity would therefore be a light conversation.
I agree with @tchrist: just use light.
However, other possibilities are frivolous, flippant, or giddy, depending on what you want to convey.
I couldn't help but wonder whether the word 'facetious' could be used as an adjectival term for 'levity'. The definitions are quite similar but I'm tentative about it's application.
(sourced from Dictionary.com so I'll leave it to you as an individual in determining it's credibility)
levity ˈlɛvɪti/ noun noun: levity; plural noun: levities
facetious fəˈsiːʃəs/ adjective adjective: facetious
I think there is a correlation between the two definitions the only ambiguity is of course one is the treatment of a matter (ostensibly an ongoing situation) whilst conversely the term facetious deals with issues (so I'm assuming -and witnessed- it only being used during esoteric conversation/debate)
I'm not adamant about it but thus far this is the only option I'm aware of (of course there will be a far more efficient word that you'll stumble upon later in life) but hopefully this should do for now :)
