摘要	Semantic prosody analysis is a corpus-linguistic method for uncovering the attitudinal or evaluative coloring a word acquires from the company it habitually keeps. Developed within John Sinclair's work on collocation and named by Bill Louw in 1993, it rests on the observation that some words carry a consistent positive or negative aura not recorded in dictionaries — the phrasal verb "set in" attracts unpleasant subjects (rot, decay, despair), and "cause" overwhelmingly precedes bad outcomes. The method retrieves a word's habitual collocates from a large corpus and reads them for a recurrent evaluative pattern, treating that pattern as part of the word's meaning. Because the prosody is built up across many instances, it is invisible from a single example and only emerges through corpus evidence, making this a paradigm case of how meaning lives in usage.	Critical Discourse Analysis (CDA) is a qualitative method that examines how language in texts and talk constructs, sustains, and challenges relations of power, ideology, and social inequality. Drawing on linguistics, social theory, and critical philosophy, CDA treats discourse not merely as communication but as social practice — a site where dominance is reproduced and where resistance can be articulated. Developed in the late twentieth century by Norman Fairclough, Teun van Dijk, and Ruth Wodak, among others, CDA is applied to political speeches, media texts, policy documents, educational materials, and institutional interactions.
