Band 5, Heft s3 - Special Issue: Natural Language Conditionals and Conditional Reasoning / Issue Editor: Mingya Liu

The concept of conditionality is central to human thought and action. Conditionals are thus a widely studied topic in cognitive science. The present paper introduces the main topics addressed in this special issue and aims to provide a non-exhaustive overview of the recent research on grammatical aspects of conditionals (i.e. morphosyntax, semantics and pragmatics) and conditional reasoning.

In this short paper I give a description of salient structural and semantic properties of adnominal conditional clauses in German, drawn from online corpora (cf. Lasersohn 1996 for the English counterpart). Facts from prosody tentatively indicate, and from Binding, DP-internal distribution and extraposition more distinctively suggest, the paper’s main conclusion: Syntactically, adnominal conditionals behave like restrictive relative clauses. I sketch a recent analysis by Frana (2017), which captures important semantic properties of the construction. A restrictor analysis of conditional clauses can be retained and indeed fits snugly with the fact that only intensional nouns co-occur with, e.g. can be modified by, adnominal conditionals.

This paper discusses word order effects in German adverbial clauses: often, the matrix clause can exhibit either V2 or V3 word order. I argue that adverbial clauses with V3 word order have an obligatory ‘biscuit’ interpretation and receive a speech act modifying interpretation, as has previously only been argued for ‘biscuit conditionals’. I show that this phenomenon holds more generally. On the other hand, a pragmatic analysis for V2 biscuit conditionals remains necessary.

This paper discusses the ways in which Mandarin Chinese expresses counterfactual conditionals, and endeavours to motivate and theorize the use of such strategies. I aim to give an overall picture of Mandarin Chinese counterfactual conditionals, a topic which has hitherto not been covered in the Chinese linguistic literature. The strategies identified are the use of special lexicalized chunks to directly encode counterfactual meaning; the creation of tense mismatch and the accompanying counterfactual meaning, either through the use of relative tense pointing toward a hypothetical past event, or through the use of some special time adverbs; and the use of pure inference over conditionals with impossible or absurd antecedents. Overlaying these strategies is the presence of context-dependent simplifications, which may prompt the language user to omit the defining features of a given strategy.

It is a common intuition that the antecedent of an indicative conditional should have something to do with its consequent, that they should be somehow connected. In fact, many conditionals sound unacceptable precisely because they seem to suggest a connection which is not there. Although the majority of semantic theories of conditionals treat this phenomenon as something pragmatic, for instance, something that is conversationally implicated, no one has offered a full-fledged pragmatic explanation of why missing-link, and, in particular, false-link conditionals strike us as odd. The aim of this paper is to explore the possibility that the link is an example of a conversational implicature. We discuss possible tests one can employ to identify conversational implicatures, and, ultimately, we show that the connection between a conditional’s antecedent and consequent fails them all.

Indicative conditionals are known to have the semantic property of nonveridicality, that is, they do not entail the truth of the antecedent. In this paper, I argue that the nonveridicality property of indicative conditionals is elastic in that it can be affected by the choice of conditional connectives and negative polarity items. Two experiments are reported, one on German and the other on English. They show that in both languages, the presence of negative polarity items conveys a weakened speaker commitment towards the antecedent, although there is cross-linguistic variation concerning the effect of conditional connectives.

In recent years, a number of arguments have been put forward stating that regular conditional clauses preceding their matrix clause are derived by means of movement: They are base-generated low in the tree and then moved to the high clause-initial position. Using data from English and German, I show in this short paper that these arguments carry over straightforwardly to less canonical conditional constructions such as V1-conditionals and conditional conjunction constructions. That suggests that, if the original arguments hold, then V1-conditionals and conditional conjunction constructions should be derived by movement as well.
