Do you have any thoughts on Quenya/Sindarin for chocolate?
The origins of the word in Mesoamerican languages are uncertain, and all the variants relate to its ancient use as a drink (confusing to the modern eye). Giving it a descriptive name is tricky because of its multitude of forms. I've come up with cacalassë, which sounds close enough and would have a meaning "continue-joy".
