Old French negation, the Tobler/Mussafia law, and V2

• Earlier Old French ne displayed contradictory properties.
• As a non-clitic it allowed a pronominal clitic to stand preverbally, but it allowed an XP preceding it to count for V2.
• Ne behaved as a clitic itself, yet acted as a host for pronominal clitics.
• OFr ne was undergoing a change in categorial status, involving the temporary coexistence of older and newer structures.
• OFr was replacing a negator in Spec NegP with a special clitic negator at the time the early texts appear.

Old French finite clauses were normally negated by preverbal ne, whose structural status is shown here to be problematic. Ne displayed contradictory syntactic properties. On the one hand it allowed null subjects, thus seeming to ‘count’ for Verb Second. It also respected the Tobler/Mussafia law by allowing a pronominal clitic to stand in preverbal position. In these respects it behaved as an ordinary clause-initial constituent. However, ne could not induce VSpro order, as an initial clause constituent normally did, and indeed allowed a constituent preceding it to do so. Ne exhibited similarly contradictory properties in behaving as a clitic itself, yet acting as a host for pronominal clitics in the forms nel and nes. These paradoxes are addressed here by postulating that ne was undergoing a change in categorial status, involving grammar competition between two structural alternatives ( Kroch, 2001): ne as a free negative clause constituent co-existed in earlier Old French with a special clitic negator ne; the Jespersen cycle of negation is seen as producing synchronic states where more than one stage of the cycle is attested.
