Title: Variation and Change in Past Tense Negation in African American English*

Abstract:
This dissertation investigates the use of /ain’t /for negation in past tense contexts in Philadelphia African American English [PhAAE]. This use of /ain’t/, which varies with /didn’t/, is a unique feature of AAE (Labov et al. 1968) and has implications for the expression of tense/aspect in the language. First, it further levels tense/aspect cues from auxiliaries in negative contexts. Second, whereas verbal complements of /didn’t /are uninflected (1a), complements of /ain’t /may either be uninflected or in preterit form (1b). This asymmetry indicates potential structural differences between /ain’t /and /didn’t/.

(1)a. They *didn’t play*yesterday.

        b. They *ain’t play(ed)* yesterday.

Consequently, this dissertation joins a quantitative study of the social and linguistic factors conditioning use of /ain’t /with a distributional investigation of its syntax and interaction with tense morphology. Toward that end, I analyze naturalistic speech data from 42 speakers in a corpus of casual conversations collected in the early 1980s from African American Philadelphians.

First, analysis of social conditioning on variation between /ain’t /and /didn’t /reveals that the use of /ain’t /in this context is a recent innovation tied to the social setting of urban Northern cities like Philadelphia. Second, an investigation of following verbal morphology indicates that the construction /ain’t/+base is preferred to /ain’t/+preterit (used only 25% of the time). Apparent time analysis reveals that /ain’t/+preterit is preferred by older speakers, suggesting that it may be an older construction. In combination with an analysis of linguistic conditioning on use of /ain’t/, specifically verbal stativy, I argue that past tense /ain’t /was reanalyzed from present perfect /ain’t/, which//varies with /haven’t/and has the same form (2).


(2)They *ain’t played*since Monday.

        “They haven’t played since Monday.”

Based on these results as well as an examination of past /vs/. perfect constructions and associated verbal forms in PhAAE, I consider the hypothesis that inflection is generated in a functional head lower than tense in /ain’t/+preterit constructions. Consequently, this dissertation demonstrates a difference in structure between /ain’t /and /didn’t /sentences and a distinction in the grammar of AAE compared to other varieties of English.
