Defining ‘periphrasis’: key notions

Some Key Notions in Non-monotonic Reasoning

This paper explores the role of some basic notions in the study of non-monotonic reasoning, such as validity, logical consequence, context, rules and assumptions. It offers some considerations about the relation between non-monotonicity and the ideal of perfect validity in logical inference and the pertinence of taking into account human limitations. I propose that work on non-monotonic reasoni...

Inflectional periphrasis in Persian

Modern Persian conjugation makes use of five periphrastic constructions. We contrast the properties of these five constructions and argue that they call for different analyses. We propose contrasting analyses relying on the combination of an HPSG approach to feature geometry and syntactic combination, and an approach to paradigm organization and morphological exponence based on Paradigm Functio...

Periphrasis as syntactic exponence

A modular approach to defining and characterising notions of simulation

We propose a modular approach to defining notions of simulation, and modal logics which characterise them. We use coalgebras to model state-based systems, relators to define notions of simulation for such systems, and inductive techniques to define the syntax and semantics of modal logics for coalgebras. We show that the expressiveness of an inductively-defined logic for coalgebras w.r.t. a not...

Lexicalism, periphrasis and implicative morphology1

Several other chapters in this book analyze grammatical phenomena according to the architectural assumptions and constraint-based representational apparatus of lexicalist theories of grammar; in the present chapter, we ask some fundamental questions concerning what it means for a theory to be lexicalist. While critically assessing some consensus beliefs among lexicalists, this exploration will ...
