This study examines Mood, Modality, and Attitude as a part of Appraisal theory in the Editorial News of the "Sydney Morning Herald" Interpersonal Meta function Analysis. Three methods were used, including (1) Indicative (Declarative and Interrogative) mood, (2) Modalization (Indicative Type), Probability (may be) and Usuality ("sometimes"), and (3) Attitude subsystem as part of Appraisal theory resources with three clauses, including Affect, Judgment, and Appreciation. The study aims to investigate the highest Interpersonal Meta function in terms of Mood, Modality, and Attitude in Editorial Discourse in Business-Related Issues. A sample of ten editorial discourses in business-related issues from The "Sydney Morning Herald" was used to examine Mood, Modality, and Attitude as part of Appraisal theory. The adopted framework in this research is interpersonal Meta function consisting of Mood, Modality, and Attitude as part of Appraisal theory. The results showed that more interrogative clauses were used, specifically 108 of 183 (59.02%) than declarative 75 of 183 (40.98%). Additionally, there were more probability positive clauses 61 of 73 (83.56%) than negative 7 of 73 (9.59%) and usuality 5 of 73 (6.85%). Similarly, appreciation clauses were used more frequently, specifically 19 of 46 (41.30%) than Judgment 14 of 46 (30.43%) and Affect 13 of 46 (28.26%). The limitation for this research is that it examined only 10 business-related editorials, which means it may not be too comprehensive. However, the information in this research can be used for educational development in Interpersonal Meta function Analysis of Editorial Discourse in Business-Related Issues Using English Systemic Linguistics. The author recommends that the future research should add more business-related editorial cases to incorporate Interpersonal Meta function, which consists of Mood, Modality, and Appraisal system as a whole by adding graduation, engagement in order to be more complete, not only Attitude as a part of Appraisal theory.
