This study explores the acceptability of preposition stranding (p-stranding) in intrasentential code-switching among US heritage speakers of Spanish, comparing its use in Spanish, English, and bilingual contexts. While p-stranding is allowed in English but not traditionally in Spanish, participants rejected p-stranding in monolingual Spanish and code-switching contexts, except for marginal acceptance in Spanish-to-English switching. The findings suggest that the language of the preposition, rather than the determiner, determines the possibility of p-stranding in bilingual code-switching.
