This chapter discusses the interaction of negation with fragment answers. The ability to use negative concord items as fragment answers has been taken as evidence of their having an inherent negative force; this chapter considers positions for and against this view, and what kind of assumptions (for the licensing of NCIs and/or for the interpretation of elliptical structure in fragments) would be required on each view, as well as considering the implications of double-negation readings for NCI fragments, and the availability of NPI fragments. The chapter also investigates the cooccurrence of a negator with a fragment answer (as in Who ate the cake?—Not John, anyway), exploring what ramifications such structures have for the syntax of fragments, and in particular for the choice between sententialist (elliptical) and non-sententialist analyses of fragments.
