What is the most joyful language in the world?

I have just come from an osteopathic appointment where I spoke French for an hour … for me, French allows me to lose myself; it’s as if the wide, low, three-rail farm gates leading to an expanse of my brain not used in the everyday have swung open on oiled hinges.

To speak French is satisfying; chocolate cake-level satisfaction for me …

It is a beautiful language; poetic, fluid, melodic, elegant …

… but it is not necessarily a joyful language.

What is the most joyful language in the world? What is the most joyful culture in the world?

What do I think that ‘joy’ even is?
