The language of Santo Domingo is Spanish, and the comparative purity with which it is spoken is remarkable when the long period of isolation of the country and the extended duration of Haitian rule are considered. In this particular Haiti offers a contrast, for though French is the official language the mass of the people speak Creole French, a patois unintelligible to anyone who has not lived in Haiti. The Dominicans do not lisp the "c" as do the Spaniards, and other peculiarities of Spanish as spoken in America are manifest, but on the whole the difference between the Dominican's Spanish and the Spaniard's Spanish may be compared to the difference between English as spoken in the United States and as spoken in England. Like several other Spanish-American nations the Dominicans are to be distinguished by their preference for certain words and endings, and by their accent and inflection. As everywhere else the unlettered classes are given to grammatical faults and provincialisms, but on the whole the vocabulary of the Dominican peasant contains fewer archaic expressions and Indian roots than that of the Porto Rican "jibaro" and is more easily understood by the outsider. Slight differences of pronunciation are noticeable in different parts of the country: the people of Seibo are inclined to use the vowel "i" instead of the consonant "r" and say "poique" instead of "porque," somewhat as the New York street urchin says "boid" for "bird"; the people of Santiago sometimes drop the "r" entirely and say "poque," as the Southern negro in the United States says "fo" for "four"; the peasants of Puerto Plata show a tendency to use the "u" instead of "o" and say "tudu" instead of "todo," like some of the inhabitants of Catalonia in Spain. The Azuans claim to speak the best Spanish of the Republic, but their claim is disputed by other provinces.
