Learners must develop the ability to vary language according to linguistic and situational factors to produce context-appropriate utterances. Likewise, interpreting the additional meaning conveyed through language variation is essential for successful communication. Nevertheless, research on the interpretation of the variable copulas in Spanish is scarce and we do not know how individual lexical items and patterns of co-occurrence of adjectives with particular copulas influence interpretation. Addressing this void, we compare interpretation of the copulas by native speakers and highly advanced, advanced, and intermediate learners. Participants completed an interpretation task containing the copulas paired with one of nine adjectives, categorized as typically co-occurring with "ser," "estar," or both copulas. The current study contributes to the body of work on communicative competence and advanced L2 proficiency by exploring the development of interpretative abilities of English-speaking learners of Spanish and the extent to which interpretation differs across adjective classes and individual adjectives.
