This is because lexical meaning is a vital component of the semantic system, responsible for conveying and clarifying meaning. However, despite its importance, it is insufficient for fully conveying meaning. Lexical entries lack crucial values, especially the recognition of probable meanings. The network of semantic relationships in any dictionary addresses meaning in a binary way. In a language that relies heavily on metaphor or derivation, like Arabic, dictionaries tailored to the Arabic language fail to provide probable meanings for words such as (eye - heart - hand), whose contextual and metaphorical meanings sometimes do not align with the body-part indication but include other potential meanings. This study is based on the hypothesis that the linguistic dictionary in general and Arabic in particular, still require an approach that allows observing the meanings across three dimensions: truth (T), indeterminacy (I), and falsehood or negation (F). By integrating phonological, semantic, and evolutionary analysis within a neutrosophical framework, a more comprehensive lexical model can be developed that captures the interaction between language, usage, context, and history. This research adopted a mixed descriptive–analytical method, combining qualitative linguistic analysis with quantitative Neutrosophic modeling. 2025 2025 254 261 10.54216/IJNS.260422 https://www.americaspg.com/articleinfo/21/show/4168
