Barbecue doesn't come from French for beard to tail; it's a Caribbean word
A popular story claims barbecue means whole animal on a spit, from the French for beard to tail. Etymologists reject it. The word traces to the Taíno of the Caribbean, whose wooden frames over fires the Spanish called barbacoa, and early English writers used it to paint Indigenous people as savages.
After 1492, Spaniards found Taíno cooks roasting meat on a wooden framework raised on sticks above a fire, a structure also used for storing food and even sleeping. They named it barbacoa, a word with probable roots in Arawak and Timucua languages. Gonzalo Fernández de Oviedo y Valdés put it in print in Spain in 1526. The Oxford English Dictionary translates the original as a framework of sticks set upon posts, and the buccaneer William Dampier described sleeping on such frames in 1697, the first known use as a noun.
The word slid from Spanish into Portuguese, French and English. An English tract from 1648 described Indigenous people drying and smoking fish this way, and Edmund Hickeringill's Jamaica Viewed of 1661 gave the first modern-form use, in a lurid passage about cannibalism. The historian Andrew Warnes finds little evidence the tale was true, and argues that images like Theodor de Bry's engravings cast smoke cookery as proof of savagery. By 1731 a Connecticut diarist was attending a barbecue as a social treat, and Samuel Johnson's 1755 dictionary defined it as dressing a whole hog.
What the word means depends where you stand. In American usage, barbecue is slow, indirect cooking in smoke at around 116 to 138 °C for hours, while grilling is fast direct heat above 260 °C. British usage treats barbecuing as the quick, direct method. Latin America has churrasco and asado, and South Africans gather around the braai, where wood is prized, charcoal tolerated and gas frowned upon.
The American South splits into sauce territories. South Carolina alone features all four recognised styles: mustard, vinegar, and light and heavy tomato. Memphis often serves hickory-smoked meat with a dry rub and sauce on the side, and Kansas City favours a thick, sweet sauce of molasses and brown sugar.
