Variable Acceptability of Differential Object Marking in Bilingual Galician–Spanish Speakers: An Exploratory Study

This paper presents an initial study of the acceptability of differential object marking (DOM) by Galician–Spanish bilinguals in Galicia. The research explores judgments provided by these bilinguals (n = 69) on DOM in both Galician and Spanish and it also explores data from a monolingual Spanish control group (n = 12). The surveys target contexts covering key syntactic and semantic–pragmatic contexts for DOM in Galician and Spanish, based on the existing literature. The Galician data reveal a tendency towards reduced acceptability of DOM compared to Spanish, but without a generalized rejection of DOM in any of the contexts. The Spanish data show variability in both groups. The study contributes insights from an under-studied language pair and aims to open avenues for further work. More generally, it enhances our understanding of DOM in bilingual grammars, particularly in microcontact situations.
