Heritage Spanish Speakers’ Syllabification of -ear and -iar Verbs

Previous studies demonstrate that some aspects of the phonological grammar of heritage Spanish speakers in the United States are monolingual-like while other aspects show influence from English (Ronquest & Rao, 2018). The syllabification of vowel sequences is an interesting trait to study in the Spanish of U.S. heritage speakers due to the tendency in English phonology to separate vowels into separate syllables and the contrasting preference for diphthongs in Spanish. Studies across several language pairs have shown that second-language learners use the syllable structure of their first language in their second language, creating non-native-like patterns. We have little understanding, however, about whether heritage speakers syllabify like monolingual Spanish speakers or if they rely on the structure of the dominant language in their environment. The present study compares the syllabification judgments of 54 heritage speakers to those of 40 monolingual speakers. The results show that heritage speakers have monolingual-like syllabification intuitions for verbs ending in -ear and -iar overall, but heritage speakers who have spent less than two years in their parents’ home country syllabify differently in reading versus listening tasks. Lexical frequency did not affect the results, indicating that syllabification intuitions are robust even in unfamiliar words.
