Pidgins, narrowly defined, are auxiliary languages reserved for communication with linguistic outgroups. Although implicitly recognized as a class of languages by many linguists, there has been little systematic typological investigation of pidgins. This dissertation presents the first large-scale typological study of morphology and functional…

Language forecasting, i.e., predicting the future state of a language, has long been regarded with a fair amount of skepticism. This is partly due to language change often being considered sudden, random, unpredictable, and viewed as the result of complex interacting factors that are not well understood (e.g., Keller 1994:72; Bauer 1994:25; Labov…

Although a growing body of research has sought to understand the relationship between word order and information structure, previous information structure (IS) analyses of verb-subject order have produced conflicting results for Medieval French, which have subsequently led to conflicting claims about the importance of IS to its word order as well…

There is a growing body of research from various perspectives in heritage language (henceforth HL) acquisition as an emerging field. Some studies proposed that HL acquisition is a differential acquisition compared with the baseline language (i.e., the language spoken by the parents or caregivers) (Kupisch & Rothman, 2018; Dubiel &…

Tikal, notably conservative in culture among its peer polities, maintains that tendency in the case of monumental texts. In this dissertation I draw on a corpus of Late Classic monuments (ca. AD 600-900) to argue, through analysis of morphological forms, that scribal tradition at Tikal was not only conservative but intentionally so. Literacy…

Dialects vary in their allophonic patterns, which can affect listeners' phonological and lexical representations. I explore how different exposure to dialect-specific allophonic patterns for two vowels in American English, /ae ai/, affects listeners' lexical processing behaviors across three perception tasks: perceptual similarity, priming, and…

Some links between linguistic meanings and markers change systematically and cyclically in what are known as "grammaticalization paths." Although the empirical observations that give rise to these characterizations are cross-linguistically robust, the representations and cognitive processes that support these shifts are still not well…

This dissertation explores the effects of frequency on the learning and use of linguistic constructions. The work examines the influence of frequency on form choice in production and meaning inference in comprehension and discusses the effect of each modality on diachronic patterns of change in language. In production, high frequency of a form…

Scholars have long debated whether Old and Middle English (ME) are different diachronic stages of one language, or whether they are two closely related languages that have different historical roots. A general assumption is that Middle and Modern English descend from Old English (OE), similar to the way Middle and Modern German descend from Old…

This dissertation approaches the idea of lexical types such as word, clitic and affix from an oblique angle. Starting with Cardinaletti & Starke's (1999) diagnostics for the Weak Pronoun, I deconstruct the category of clitic, breaking it down into two binary qualities: the syntactic primitive of being linked to a head of a different basic…

This dissertation explores dialect diversification in the long-distance New World Plautdietsch speech community. Plautdietsch dialects are traditionally classified as belonging to one of two types: either Chortitza or Molotschna. The traditional dialect classification has recently come under scrutiny because speakers rarely use features exclusive…

Predicting the outcome of language contact situations is complicated by the fact that the primary agents of linguistic change--individual speakers--are unpredictable (van Coetsem, 2000; Thomason, 2001). My dissertation examines the variety of Spanish spoken in Galicia, Spain, where individual language choices are often motivated not by utility but…

This thesis examines the role of the African substrate languages in the emergence of Atlantic Creole grammatical structures. Alleyne (1980) and Faraclas (1990) have convincingly demonstrated that a survey of the grammatical features that typify the Colonial Era English-Lexifier Creoles of the Atlantic reveals remarkable similarities with those…

The phonological inventory of Old Okinawan is often reconstructed according to modern Ryukyuan languages. Although the importance of historical resources is never ignored in the study of Okinawan historical linguistics, reconstruction based on historical sources is not well investigated yet, due to the two reasons that a) authors of previous…

Across the centuries, the question of the origin of language has captivated the human imagination. Many theories have been proposed to address fundamental questions such as: Where do languages come from? How do they evolve? What are the societal drivers of this change? Historically, one of the biggest challenges in addressing these questions has…
