Inserção não convencional da coda (r) ao final de verbos em textos digitais: condicionantes estruturais, lexicais e gráficos

Abstract

This thesis investigates variation in the unconventional insertion of the final coda (r) in verbs, as in a. esse álbum estar maravilhosooo; b. quem te viu e quem te ver; and c. perdir o resto da pose que eu tinha. The analysis draws on a corpus of texts published on digital platforms. This study extends the work of Mendonça (2021), who examined similar data in which the insertion of the grapheme <r> produced forms whose spellings coincided with the standard orthography of infinitives. The theoretical framework integrates principles from the Theory of Linguistic Variation and Change (Weinreich; Labov; Herzog, 2006 [1968]) and Usage-Based Models (Bybee, 2013, 2016 [2002]; Pierrehumbert, 2001, 2003). The study aims to understand (i) which internal constraints influence the variability of unconventional uses of the coda (r) in writing; (ii) whether the insertion of <r> is favored when it results in coincidence with the infinitive form; and (iii) what role lexical items play in the unconventional marking of <r> in verbs. The conditioning factors investigated include: i. final syllable tonicity; ii. word length; iii. preceding vowel; iv. graphic coincidence; vii. lexical item; and viii. data source. Results from two rounds of logistic regression using the Rbrul software (one with fixed effects and another with random effects) indicate that structural, lexical, and graphic factors significantly influence the phenomenon. The most relevant variables were graphic coincidence, final syllable, preceding vowel, and word length, as well as the interaction between word length + final syllable tonicity. The findings suggest that the graphic memory of infinitive verb forms contributes to the hypercorrect use of <r>, highlighting the roles of linguistic conditioning and frequency effects as underlying cognitive mechanisms in hypercorrection processes.
