The article questions the hypothesis that there exists a double plural marker in Dominican Spanish, the -e appended to nouns ending in consonants, and a second one that attaches to all nouns and adjectives, represented by -se, under some pragmatic conditions of focus. Instead I demonstrate that there is a single plural marker, -e, and a zero plural markers that attaches to vowel-ending non-verbs. It is further demonstrated that the occurrence of -se is indeed an enhancing mechanism that Dominican speakers use for all lexical categories, including adverbs, which never inflect for plurality, as in la mayoría viven abájose "most (people) live DOWN THERE", where -se attaches to the adverb abajo. Some of the enhancing properties discussed refer to pragmatic effects, promiscuity in regard to input category, alternative outputs, interspeaker variations, special syntax, among others which were first proposed by Arnold Zwicky.
