The word "chocolate" entered the English language from Spanish.[5] How the word came into Spanish is less certain, and there are competing explanations. Perhaps the most cited explanation is that "chocolate" comes from Nahuatl, the language of the Aztecs, from the word chocolātl, which many sources say derived from xocolātl [ʃokolaːtɬ], combining xococ, sour or bitter, and ātl, water or drink.[5] The word "chocolatl" does not occur in central Mexican colonial sources, making this an unlikely derivation.[6] Another derivation comes from the Yucatec Mayan word chokol meaning hot, and the Nahuatl atl meaning water.[7] The Nahuatl term, chicolatl, meaning "beaten drink", may derive from the word for the frothing stick, chicoli.[8]
