lightsome

/ˈlaɪtsəm/

If you're lightsome, you're graceful and agile in your movements. A lightsome dancer moves nimbly and effortlessly across the stage.

You can be physically lightsome, skipping lightly across the sand on the beach, or lightsome in your very nature, cheerful and carefree. A lighthearted, happy-go-lucky child who's dancing and skipping around is the perfect illustration of the adjective lightsome. It's rarely used these days, mainly considered literary — so you're most likely to read it in an old book.
