As humans, we use language with ease and speed, solving the complex computational problem of processing form and meaning seemingly without effort. This dissertation studies how the properties of language enable us to achieve this, by investigating what is computationally difficult about language, and what is easy. We first investigate the…

Ellipsis plays a key role in the understanding of the relationship between what is uttered and what is understood. In elliptical utterances, less is said than is understood. How is it that a mere fragment of a sentence can be understood as something more? This dissertation explores the syntax of one type of elliptical phenomena, Stripping. A…

This dissertation uses a corpus of tokens retrieved from broadcast news stories and print news articles to examine the array of constructions used to encode stative predications in Modern Standard Arabic. A state is defined as a situation that includes its reference time, whether that time is encoding time or another time of orientation. A range…

Or is commonly understood to be a conjunction linking two or more constituents. Ending a sentence with "or" is considered non-canonical in written interaction, but ending a turn with "or" occurs regularly in spoken interaction. This dissertation investigates the interactional work of turn-final or as in "Did his oxygen get…

Because language provides the framework through which knowledge is constructed, it is crucial to consider the ways in which students with limited English proficiencies are able to express their understanding. English language learners (ELLs) make up a significant portion of the student body in the education system and represent many ethnic and…

This dissertation examines Spanish Direct Object clitic pronouns in Argentine spoken Spanish of adults and children (ages 4;0-7;0). It concentrates on (Finite verb + Nonfinite verb) constructions that allow both pre-verbal (Proclisis) and a postverbal (Enclisis) clitic placement. Previous corpus studies have shown that lexical (finite verb),…

The data on language acquisition in children with specific language impairment (SLI) primarily come from studies in English reporting particular morphemes that differentiate them from their typically developing (TYP) peers, but markers of impairment vary cross-linguistically. There is some cross-linguistic evidence that SLI disrupts language…

Brazilian Portuguese (henceforth BP) has for long been considered as a Null-subject language due to its variability in regards to subject expression (e.g. "Era bom porque eu diminuia de peso...era muito gordinha" "That was good because then I could lose some weight...(I) was a bit chubby." C33:179). Such variability has been…
