Chain reduction via substitution: Evidence from Mayan

Extraction out of adjuncts in K'ichean languages shows that "overt traces" are possible.

We argue that deletion is not the only way that chain links created by A′-movement can be affected at PF. Chain links can also be substituted by a morpheme. This substitution delivers a linearizable output (in a manner parallel to deletion), creating overt “traces” on the surface. We demonstrate the virtues of our proposal through the empirical lens of adjunct extraction in two Mayan languages of the K’ichean branch: K’iche’ and Kaqchikel. In these languages, extraction of low adjuncts triggers the appearance of a verbal enclitic wi. The distribution of the enclitic upon long distance extraction shows that it must be analyzed as a surface reflex of substitution of a chain link. Our proposal provides evidence that movement proceeds successive cyclically and has two additional theoretical consequences: (i) C0 must be a phase head (contra den Dikken 2009; 2017), (ii) v0 cannot be a phase head (in line with Keine 2017).

Optional agreement in Santiago Tz'utujil (Mayan) is syntactic

Agreement is optional only for complements, and is conditioned by whether the argument is a DP or a reduced nominal.

Some Mayan languages display optional verbal agreement with 3pl arguments (Dayley 1985; Henderson 2009; England 2011). Focusing on novel data from Santiago Tz’utujil (ST), we demonstrate that this optionality is not reducible to phonological or morphological factors. Rather, the source of optionality is in the syntax. Specifcally, the distinction between arguments generated in the specifer position and arguments generated in the complement position governs the pattern. Only base-complements control agreement optionally; base-specifers control agreement obligatorily. We provide an analysis in which optional agreement results from the availability of two syntactic representations (DP vs. reduced nominal argument). Thus, while the syntactic operation Agree is deterministic, surface optionality arises when the operation targets two diferent sized goals.

Proxy Control: A new species of control in grammar

In German and Italian, 'Maria asked Bill to leave early' may be used to mean that Maria sought permission for people she represents. Aaron and Sandhya provide an analysis.

The control dependency in grammar is conventionally distinguished into two classes: exhaustive (ii) and non-exhaustive (ii + (j)). Here, we show that, in languages like German and Italian, some speakers allow a new kind of “proxy control” which differs from both, such that, for a controller i, and a controllee jj = proxy(i). The proxy function picks out a set of individuals that is discourse-pragmatically related to i. For such speakers, the German/Italian proxy control equivalent of the sentence: “Mariai asked Billj (for permission) [PRO𝑝𝑟𝑜𝑥𝑦(𝑖)proxy(i) to leave work early]” would thus mean that Maria asked Bill for permission for some salient set of individuals related to herself to leave early. We examine the theoretical and empirical properties of this new control relation in detail, showing that it is irreducible to other, more familiar referential dependencies. Using standard empirical diagnostics, we then illustrate that proxy control can be instantiated both as a species of obligatory control (OC) and non-obligatory control (NOC) in German and Italian and develop a syntactic and semantic model that derives each and details the factors conditioning the choice between the two. We also investigate the factors that condition different degrees of exhaustiveness (exhaustive vs. partial vs. proxy) in control, which then sheds light on why proxy control obtains in some languages, but not others and, within a language, is possible for some speakers but not others.

Processing adjunct control: Evidence on the use of structural information and prediction in reference resolution

How does online comprehension of adjunct control ("before eating") compare to resolution of pronominal anaphora ("before he ate")?

The comprehension of anaphoric relations may be guided not only by discourse, but also syntactic information. In the literature on online processing, however, the focus has been on audible pronouns and descriptions whose reference is resolved mainly on the former. This paper examines one relation that both lacks overt exponence, and relies almost exclusively on syntax for its resolution: adjunct control, or the dependency between the null subject of a non-finite adjunct and its antecedent in sentences such as Mickey talked to Minnie before ___ eating. Using visual-world eyetracking, we compare the timecourse of interpreting this null subject and overt pronouns (Mickey talked to Minnie before he ate). We show that when control structures are highly frequent, listeners are just as quick to resolve reference in either case. When control structures are less frequent, reference resolution based on structural information still occurs upon hearing the non-finite verb, but more slowly, especially when unaided by structural and referential predictions. This may be due to increased difficulty in recognizing that a referential dependency is necessary. These results indicate that in at least some contexts, referential expressions whose resolution depends on very different sources of information can be resolved approximately equally rapidly, and that the speed of interpretation is largely independent of whether or not the dependency is cued by an overt referring expression.

Events in Semantics

Event Semantics says that clauses in natural languages are descriptions of events. Why believe this?

Publisher: The Cambridge Handbook of the Philosophy of Language

Event Semantics (ES) says that clauses in natural languages are descriptions of events. Why believe this? The answer cannot be that we use clauses to talk about events, or that events are important in ontology or psychology. Other sorts of things have the same properties, but no special role in semantics. The answer must be that this view helps to explain the semantics of natural languages. But then, what is it to explain the semantics of natural languages? Here there are many approaches, differing on whether natural languages are social and objective or individual and mental; whether the semantics delivers truth values at contexts or just constraints on truth-evaluable thoughts; which inferences it should explain as formally provable, if any; and which if any grammatical patterns it should explain directly. The argument for ES will differ accordingly, as will the consequences, for ontology, psychology, or linguistics, of its endorsement. In this chapter I trace the outlines of this story, sketching four distinct arguments for the analysis that ES makes possible: with it we can treat a dependent phrase and its syntactic host as separate predicates of related or identical events. Analysis of this kind allows us to state certain grammatical generalizations, formalize patterns of entailment, provide an extensional semantics for adverbs, and most importantly to derive certain sentence meanings that are not easily derived otherwise. But in addition, it will systematically validate inferences that are unsound, if we think conventionally about events and semantics. The moral is, with ES we cannot maintain both an ordinary metaphysics and a truth-conditional semantics that is simple. Those who would accept ES, and draw conclusions about the world or how we view it, must therefore choose which concession to make. I discuss four notable choices.

Transparency and language contact: The case of Haitian Creole, French, and Fongbe

Haitian Creole supports the hypothesis that language contact leads to more transparent relations between meaning and form.

Linguistics

When communicating speakers map meaning onto form. It would thus seem obvious for languages to show a one-to-one correspondence between meaning and form, but this is often not the case. This perfect mapping, i.e. transparency, is indeed continuously violated in natural languages, giving rise to zero-to-one, one-to-many, and many-to-one opaque correspondences between meaning and form. However, transparency is a mutating feature, which can be influenced by language contact. In this scenario languages tend to evolve and lose some of their opaque features, becoming more transparent. This study investigates transparency in a very specific contact situation, namely that of a creole, Haitian Creole, and its sub- and superstrate languages, Fongbe and French, within the Functional Discourse Grammar framework. We predict Haitian Creole to be more transparent than French and Fongbe and investigate twenty opacity features, divided into four categories, namely Redundancy (one-to-many), Fusion (many-to-one), Discontinuity (one meaning is split in two or more forms,) and Form-based Form (forms with no semantic counterpart: zero-to-one). The results indeed prove our prediction to be borne out: Haitian Creole only presents five opacity features out of twenty, while French presents nineteen and Fongbe nine. Furthermore, the opacity features of Haitian Creole are also present in the other two languages.

There is a simplicity bias when generalising from ambiguous data

How do phonological learners choose among generalizations of differing complexity?

How exactly do learners generalize in the face of ambiguous data? While there has been a substantial amount of research studying the biases that learners employ, there has been very little work on what sorts of biases are employed in the face of data that is ambiguous between phonological generalizations with different degrees of complexity. In this article, we present the results from three artificial language learning experiments that suggest that, at least for phonotactic sequence patterns, learners are able to keep track of multiple generalizations related to the same segmental co-occurrences; however, the generalizations they learn are only the simplest ones consistent with the data.

Null Objects in Korean: Experimental Evidence for the Argument Ellipsis Analysis

Experimental evidence supports an analysis of Null Object constructions in Korean as instances of object ellipsis.

Null object (NO) constructions in Korean and Japanese have receiveddifferent accounts: as (a) argument ellipsis (Oku 1998, S. Kim 1999, Saito 2007, Sakamoto 2015), (b) VP-ellipsis after verb raising (Otani and Whitman 1991, Funakoshi 2016), or (c) instances of base-generated pro (Park 1997, Hoji 1998, 2003). We report results from two experiments supporting the argument ellipsis analysis for Korean. Experiment 1 builds on K.-M. Kim and Han’s (2016) finding of interspeaker variation in whether the pronoun ku can be bound by a quantifier. Results showed that a speaker’s acceptance of quantifier-bound ku positively correlates with acceptance of sloppy readings in NO sentences. We argue that an ellipsis account, in which the NO site contains internal structure hosting the pronoun, accounts for this correlation. Experiment 2, testing the recovery of adverbials in NO sentences, showed that only the object (not the adverb) can be recovered in the NO site, excluding the possibility of VP-ellipsis. Taken together, our findings suggest that NOs result from argument ellipsis in Korean.

The structure of Polish numerically-quantified expressions

What is the syntax of "five witches" in Polish, with genitive on "witches", accusative on "five", and third-singular-neuter agreement on a verb? Paulina Lyskawa gives a new answer that manages to preserve ordinary theories of case and agreement.

Cross-linguistically, numerically-quantified expressions vary in terms of their internal syntactic structure (e.g. the category of the numeral, its position in the nominal projection) as well as interaction with the external syntax (e.g. occurring in the subject positions, determining agreement and concord). Here, I investigate Polish numerically-quantified expressions of the 5+ type, such as pięć czarownic ‘five witches’, focusing on three morphosyntactic properties: the genitive case on the quantified noun, the accusative case on the numeral, and the occurrence of 3sg neuter verbal agreement. I argue that all of these properties can be captured within existing theories of case and agreement, in terms of a null head that takes the quantified noun phrase as its complement, and a numeral phrase as its specifier. Genitive on the noun is structural, accusative on the numeral is licensed by a null preposition, and default agreement is a result of the case-discriminating nature of verbal agreement. This proposal has implications for the broader theory of agreement and case assignment in Slavic languages and beyond.

Headedness and the Lexicon: The Case of Verb-to-Noun Ratios

Is there a correlation between the relative size of a lexical class, such as verbs in relation to nouns, and whether members of that class precede or follow a dependent in phrases they head? This paper finds that there is.

This paper takes a well-known observation as its starting point, that is, languages vary with respect to headedness, with the standard head-initial and head-final types well attested. Is there a connection between headedness and the size of a lexical class? Although this question seems quite straightforward, there are formidable methodological and theoretical challenges in addressing it. Building on initial results by several researchers, we refine our methodology and consider the proportion of nouns to simplex verbs (as opposed to light verb constructions) in a varied sample of 33 languages to evaluate the connection between headedness and the size of a lexical class. We demonstrate a robust correlation between this proportion and headedness. While the proportion of nouns in a lexicon is relatively stable, head-final/object-verb (OV)-type languages (e.g., Japanese or Hungarian) have a relatively small number of simplex verbs, whereas head-initial/verb-initial languages (e.g., Irish or Zapotec) have a considerably larger percentage of such verbs. The difference between the head-final and head-initial type is statistically significant. We, then, consider a subset of languages characterized as subject-verb-object (SVO) and show that this group is not uniform. Those SVO languages that have strong head-initial characteristics (as shown by the order of constituents in a set of phrases and word order alternations) are characterized by a relatively large proportion of lexical verbs. SVO languages that have strong head-final traits (e.g., Mandarin Chinese) pattern with head-final languages, and a small subset of SVO languages are genuinely in the middle (e.g., English, Russian). We offer a tentative explanation for this headedness asymmetry, couched in terms of informativity and parsing principles, and discuss additional evidence in support of our account. All told, the fewer simplex verbs in head-final/OV-type languages is an adaptation in response to their particular pattern of headedness. The object-verb/verb-object (OV/VO) difference with respect to noun/verb ratios also reveals itself in SVO languages; some languages, Chinese and Latin among them, show a strongly OV ratio, whereas others, such as Romance or Bantu, are VO-like in their noun/verb ratios. The proportion of nouns to verbs thus emerges as a new linguistic characteristic that is correlated with headedness.
