Literal translation
he throws himself gaily into the dance
Meaning
he throws himself into it wholeheartedly
Explanation
This expression describes someone throwing themselves into a task, an undertaking, or an activity with enthusiasm and good cheer, without dragging their feet or grumbling. The literal image relies on brande, which denotes both the branle, a lively communal folk dance, and by extension the movement, the bustle, the shared rhythm of a collective action: going gaily to the brande means joining the general movement with the same joyful drive as someone stepping into a round dance or a ball. The word gai reinforces this image, underlining that the commitment happens without apparent effort, almost for pleasure, unlike someone who drags along or has to be pushed. The expression extends beyond dancing to designate any collective activity, a job, a celebration, even a chore, taken on with the same spirit. The register is familiar and warm, used in praise of someone whose enthusiasm is noticed and appreciated by those around them, particularly in contexts of communal work or village festivities.
