Items in the mental lexicon have three storage and processing strata, the concept, lemma, and lexeme, which equate to semantic, syntactic and phonological information. Lexical items relate to each other at each stratum. Bilingual lexicons, which contain items from all languages, may contain cognates, items sharing concepts and with overlapping…

When learning a language, typically-developing infants face the daunting task of learning both the sounds and the meanings of words. In this dissertation, we focus on a source of variability that complicates the one-to-one relationship between words and their meanings: wordform variability. In Chapter 1 we make a distinction between the micro…

The current research investigates interactions between lexical and structural processing in the construction and interpretation of transitive and dative sentence structures, and relates speakers' choice of structure in sentence production to STM processes and recent/long-term language experience conditioned on lexical information. Study 1…

This dissertation investigates a typologically rare linguistic phenomenon found in Irish from three different perspectives: how it challenges phonological theory, how it is used by contemporary speakers, and how its written representation affects its acquisition. Initial consonant mutation (ICM), as it appears in the Celtic languages, is known to…

This dissertation defends a strong version of the view that linguistic surface complexity is the product of interactions between deep syntactic mechanisms and shallow interface-specific mechanisms. I argue that current developments in the theory of locality in Distributed Morphology (Embick 2010, Marantz 2013) impose boundaries on syntactic…

To avoid potential miscommunication resulting from structural ambiguity, speakers and listeners often rely on differences in prosodic realization. For instance, the sentence "Jennifer blackmailed the boss of the clerk [who was dishonest"][subscript RC'] is realized with different prosody depending on the attachment of the relative clause…

The objective of the current study is to contribute to the larger body of sociophonetic variation research by describing and analyzing Spanish as spoken in a small Puerto Rican community in the US. First, I describe phonological and morphosyntactic features of Spanish as used by four different groups of Puerto Rican informants in Amsterdam, New…

Purpose: The purpose of this study is to explore the phonological development of Spanish-speaking preschoolers who are acquiring African American English (AAE) in North Carolina (NC). Understanding the phonological structure of the Spanish-AAE language combination will improve diagnostic accuracy for this group of children. Method: Four Black…

This is a grammar which provides a detailed linguistic description of the phonology, morphology, syntax, discourse, lexicon and cultural environment of the Mehek language and its speakers. Mehek is a language spoken in Papua New Guinea by approximately 6300 people. It belongs to the Sepik language family, Tama branch. The theoretical background…

The study abroad (SA) experience is often viewed as an opportunity to gain proficiency in a foreign language due to immersion in the target language and culture. Nevertheless, the increased amount of research conducted on SA over the last two decades indicates that it does not necessarily lead to gains in all areas (Collentine & Freed, 2004;…

The starting point of this dissertation is the observation that pronouns that are obligatorily dependent on a sufficiently local antecedent are persistently silent. The classical hypothesis has been that silence is a lexical property of such elements. The central claim of this dissertation is that silence is instead a product of syntax--of the way…

This dissertation is concerned with how elliptical sentences are generated. To be specific, I investigate when and in what module ellipsis occurs, and what is elided as a result of ellipsis. With regard to the first research question, I propose that XP ellipsis occurs as soon as all the featural requirements of the licensor of XP ellipsis are…

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…

The traditional Philadelphia allophonic /ae/ system (henceforth: PHL shown in (1) below) is characterized by a set of complicated conditioning factors and a dramatic acoustic distinction between the two allophones. In recent years, some Philadelphians have begun to exhibit a new allophonic system (NAS, shown in (2) below). Like PHL, NAS is…

Using data from Arizona, United States, the present study seeks to further our understanding of lone other language items (LOLIs) in bilingual discourse and their status as either borrowings or codeswitches by measuring the degree of incorporation that can indicate a LOLI's status as a borrowing or codeswitching. To accomplish this aim, nouns from…
