As an extreme example of polysemy in the study of linguistics, contronymy has been a research topic of great interest across various languages for decades. Contronymy, also known as the dust puzzle, refers to a puzzle-like linguistic phenomenon in which a single lexical unit possesses two or more contradicting senses at the word-internal level. This paper, based on a variety of descriptive literature on contronymy thus far, aims to explain the mechanism of one specific branch of contronymy — contronymous verbs — by adopting the Lexical Conceptual Core (LCC) and Lexical Conceptual Specification (LCS) approaches. Fifty-one contronymous verbs, including dust, skin, and sanction, were extracted for analysis from seven representative and recent papers on contronymy: Karaman (2008), Klegr (2013), Dziedziul (2018), Ozyumenko (2019), Povstyanaya, Kosareva, Gavrikova, Arkhipova, and Belova (2019), Kajberuny and Hakobyan (2020), and Fu (2020). Then, these contronymous verbs were divided into five groups, taking into consideration their temporal, semantic, pragmatic, or cultural properties. The LCC and LCS approaches have been validated as an effective method for analyzing the mechanism of contronymous verbs. These approaches may offer new insights into how lexical ambiguity is structured and interpreted across different linguistic phenomena, thereby contributing to both theoretical and applied linguistics.
