 This paper proposes an HPSG account of the French tense and aspect system, focussing on the analysis of the passé simple (simple past) and imparfait (imperfective) tenses and their interaction with aspectually sensitive adjuncts. Starting from de Swart's~(1998) analysis of the semantics of tense and aspect, I show that while the proposed semantic representations are appropriate,  the analysis of implicit aspectual operators as coercion operators is inadequate.

The proposed HPSG analysis relies on Minimal Recursion Semantics to relate standard syntactic structures with de Swart-style semantic representations. The analysis has two crucial features: first, it assumes that the semantic contribution of tense  originates in the verb's semantic representation, despite the fact that tense can get wide scope over other semantic elements. Second, it allows the occurrence of implicit aspectual operators to be controlled by the verb's inflectional class, which accounts for their peculiar distribution.

Departing from the exhaustive indexation, syntax-driven approach to binding, we argued for an alternative, semantics-oriented rationale for binding principles.  Under this new understanding of the nature of grammatical constraints on anaphoric binding, these principles are viewed as contributing to circumscribe the contextually determined semantic value of  anaphoric nominals. This conceptual shift helps to find a fully fledged formal specification of binding principles with the HPSG lean description formalism where these constraints are entered in the grammar as part of the information kept at the lexical entries of anaphoric expressions.

 We present an approach to VP ellipsis that allows the direct derivation of source and target sentences (the former need not be unique) during semantic construction. Specific syntactic constituent structures are associated with ellipsis potential, which can then be discharged by pro-verbs like did (too). The determination of source and target sentence, which is done with semantic features in an HPSG framework, is coupled with a comprehensive analysis of ellipsis, which also handles its interaction with scope and anaphora.

 Case-matching effects in in German VP coordination and German free relatives have received a fair amount of attention in recent syntactic theorizing and have been cited by Ingria (1990) as a potential challenge to constraint-based and unification-based approaches to syntax such as HPSG and LFG.

This paper considers another construction in question: case-matching phenomena in Bavarian relative clauses, for which Bayer (1983) develops an inherently derivational account. The present paper offers a purely declarative account of Bavarian relative clauses in HPSG and shows that the analytical tools provided by unification-based or constraint-based grammar formalisms completely suffice to provide a fully adequate and comprehensive analysis of the data.
