While universally present in languages, negation is well-known to manifest a surprising cross-linguistic diversity of forms. In creole languages, however, negation and negative dependencies have been regarded as largely uniform. Creole languages as Bickerton claims in Roots of Language , generally exhibit negative concord, a construction popularly dubbed 'double negation', where several expressions, each negative on its own, come together with a logic-defying single negation interpretation. While this construction - problematic for compositionality if the meaning of sentences emerge from the meaning of their parts - has fostered much research, the fertile data terrain that creole languages offer for its understanding is rarely taken into account. Aiming at bridging this gap, this book offers a wealth of theoretically informed empirical investigations of negative relations in a wide variety of creole languages. Uncovering a far more complex negative landscape than previously assumed, the book reveals the challenging richness that a thorough comparative study of creoles delivers.
