Our word copal is the Mexican copalli. There are a few other Mexican words which have been naturalized in our European languages, of course indicating that the things they represent came from Mexico. Ocelotl is ocelot; Tomatl is tomata; Chilli is the Spanish chile and our chili; Cacahuatl is cacao or cocoa; and Chocolatl, the beverage made from the cacao-bean with a mixture of vanilla, is our chocolate.
Cacao-beans were used by the Mexicans as money. Even in Humboldt’s time, when there was no copper coinage, they were used as small change, six for a halfpenny; and Stephens says the Central Americans use them to this day. A mat in Mexican is petlatl, and thence a basket made of matting was called petlacalli—“mathouse.” The name passed to the plaited grass cigar-cases that are exported to Europe; and now in Spain any kind of cigar-case is called a petaca.
The pretty little ornamented calabashes—used, among other purposes, for drinking chocolate out of—were called by the Mexicans xicalli, a word which the Spaniards made into jícara, and now use to mean a chocolate-cup; and even the Italians have taken to it, and call a tea-cup a chicchera.
