La expresión lingüística de la actitud en el género de opinión: el modelo de la valoración

located within the framework of systemic functional linguistics (halliday, 1994; iedema, fezz y white, 1994; martin, 2000; white, 2003) appraisal theory constitutes a valuable theoretical and analytic tool in the study of evaluation in language. this approach elaborates on the notion of interpersonal meaning and explores, describes and explains the way language is used to evaluate, to adopt stances, to construct textual personas and to manage interpersonal positionings and relationships. more particularly, appraisal is concerned with the language of attitude and emotion. in this context, this work examines evaluative resources in the broad semantic domain of attitude, focussing upon the data provided by british national newspapers comment articles. further, this paper intends to show the role evaluative meanings play in the dissemination of ideology, in the constitution of textual styles and authorial identities, and in the negotiation of writer/reader relationships.
