 According to the authority on the Spanish language, the Royal Spanish Academy, the Spanish word "chocolate" is derived from the Nahuatl word "xocolatl" (pronounced ), which is made up from the words "xococ" meaning sour or bitter, and "atl" meaning water or drink.However, as William Bright noted the word "chocolatl" doesn't occur in central Mexican colonial sources making this an unlikely derivation.Santamaria gives a derivation from the Yucatec Maya word "chokol" meaning hot, and the Nahuatl "atl" meaning water.
