Lexical and Grammatical Means of Expressing the Modal Meanings of Possibility and Impossibility in Modern Standard Arabic

This article examines the lexical and grammatical means of expressing the modal meanings of possibility and impossibility in Modern Standard Arabic. It analyzes how these modal meanings are conveyed through a range of language units, including modal verbs, particles, adverbs, and syntactic constructions. The study categorizes modal expressions into epistemic, deontic, and dynamic modalities, with special focus on the semantic and syntactic features of each. The research also explores the functional differences between synonymous expressions and contextual conditions under which they are employed. Comparative insights are provided to highlight the distinctive features of possibility-related modal expressions and their correlation with negation in expressing impossibility. The findings contribute to a deeper understanding of modality in Arabic and offer implications for both linguistic theory and practical language instruction.
