In the Shahnameh, virtue is shaped less through explicit moral instruction or isolated ethical terms than through narrative action and the interaction of character, judgment, and heroic conduct. Drawing on corpus stylistics and Conceptual Metaphor Theory, this study examines the linguistic and narrative organization of virtue through three key lexical items: dād “justice/order,” kherad “wisdom/discernment,” and nām “name/reputation.” The corpus consists of the complete text of the Shahnameh. Data were analyzed through frequency lists, collocation analysis, concordance lines, lexical clusters, and manual filtering, so that formal or irrelevant occurrences were excluded and only instances contributing to ethical, narrative, and metaphorical meaning were retained. The findings show that dād, kherad, and nām do not function as separate concepts; rather, through their co-occurrence and interaction, they form a conceptual network of virtue. Kherad is associated with discernment, clear-sightedness, judgment, and the regulation of action, foregrounding the inward and cognitive dimension of virtue. Dād carries this discernment into conduct, kingship, justice, and social order, marking the boundary between right and wrong. Nām shows that ethical action in the Shahnameh does not end at the moment of performance, but continues through honor, good reputation, collective memory, and the lasting trace of deeds. Shared collocations further indicate that virtue is linked to soul and spirit, the sacred, royal order, heroic action, and collective memory. From this perspective, virtue in the Shahnameh is not merely an individual trait, but a linguistic and narrative process in which right discernment, just conduct, and the continuation of good name form three interdependent dimensions of a single value system.
