Sintesi	Longitudinal Critical Discourse Analysis (LCDA) combines the critical discourse analysis tradition — which examines how language constructs and reproduces power, ideology, and social inequality — with a longitudinal design that collects and compares texts at multiple time points. By tracking discursive change over time, LCDA reveals how ideological representations, social identities, and power relations shift, stabilise, or are contested across different historical or political periods.	Longitudinal Discourse Analysis (LDA) is a qualitative research approach that examines how discourse — language in use, texts, talk, and representational practices — changes across time. Rather than analysing a single snapshot of language, LDA collects and compares discourse data at multiple points to uncover how meanings, identities, ideologies, or social practices evolve, stabilise, or shift under the influence of historical, institutional, or societal forces.
