This research investigates the phenomenon of sound symbolism in Mapudungun, a language isolate spoken by the Mapuche people in Chile and Argentina. The study, conducted by a team including linguist and native speaker María Catrileo, addresses a gap in the literature regarding the integration of iconic sound-meaning relationships into grammatical systems. While sound symbolism has been documented in various languages, the specific mechanisms by which it operates in Mapudungun—particularly through coronal consonant alternations that convey affective values—remain underexplored. This research is significant as it contributes to our understanding of how sound symbolism can influence grammar and meaning, challenging the traditional view of linguistic arbitrariness.

The methodology employed in this study is multifaceted, combining corpus analysis with metalinguistic commentary and collaborative insights from a native speaker. The researchers examined a 400-year textual record of Mapudungun, focusing on coronal consonant alternations that denote diminutive or augmentative meanings. The study is novel in its approach, as it integrates historical data with contemporary linguistic practices, allowing for a diachronic perspective on the phenomenon. By adopting a “shared reading” approach with traditional educator Fresia Loncon Antileo, the researchers ensured that the findings reflect both linguistic theory and cultural context, enhancing the rigor of the analysis.

Key findings indicate that coronal consonants in Mapudungun exhibit systematic alternations that encode affective meanings. Specifically, palatalization of coronal consonants is associated with diminutive and positive connotations, while dentalization correlates with augmentative and pejorative meanings. For example, the transformation of an alveolar consonant to its palatal form can signify tenderness or politeness, whereas dentalization may imply rudeness or sarcasm. The study highlights that these alternations are not arbitrary but are governed by semantic and pragmatic factors, suggesting a complex interplay between phonology and meaning. The researchers propose that these alternations can be understood as floating evaluative morphemes, which are distinguished by their positive or negative polarity.

The broader significance of this research lies in its implications for fields such as language technology, machine translation, and NLP. Understanding the mechanisms of sound symbolism can inform the development of more nuanced language processing systems that account for affective meaning in communication. Additionally, this study provides insights into the cognitive and social dimensions of language use, which can enhance translation studies by emphasizing the importance of context and speaker intention. By bridging the gap between linguistic theory and practical application, this research encourages further exploration of sound symbolism across languages, enriching our understanding of the intricate relationship between form and meaning in human communication.
