Acehnese (“ah-chay-NEEZ”) lacks this grammatical feature everywhere except in its first-personal pronouns. Classical Arabic’s word for “camel” uniquely admits eight possible options for this grammatical feature. The Tanoan languages Kiowa and Jemez (“HAY-mez”) feature a rare “inverse” form of this grammatical feature, which marks whether this feature has the expected status for its noun class. Besides recursion and color, Daniel Everett argued that the Pirahã (-5[1])language (10[1])lacks both this feature and any words for related concepts. The “paucal” form of this feature is most (-5[1])closely approximated by the English phrase “a few.” For 10 points, name this grammatical feature in which words are modified according to the quantities involved, such as English’s singular and plural. ■END■ (10[2])
