In Lewis Carroll’s Through the Looking Glass, Humpty Dumpty explains to Alice, “When I use a word … it means just what I choose it to mean — neither more nor less.” When Alice questions this license, Humpty Dumpty replies, “The question is … which is to be master — that’s all.” The present article offers a lexicon of words that are used by human beings, however unintentionally or ingenuously, to maintain their mastery or prerogatives over other animals. A motivating (...) assumption of the article is that putting on display the verbal menagerie in animal agriculture, animal experimentation, and the rest of the industries and institutions that use nonhuman animals, could go a long way toward eliminating these enterprises, since they are built as much on equivocation as on exploitation.
