Meaning and elaboration
Meaning: The beloved consort of Krishna, ever devoted, embodying the soul's yearning for the Divine.
Elaboration
Radha is a central figure in Vaishnavism, especially in the Gaudiya Vaishnava tradition, but she is not usually invoked as an aspect or name of Mahakali in the Shakta traditions. Radha and Mahakali belong to different spiritual lineages and express different theological principles, even though both are revered as supreme manifestations of the Divine Feminine within their own traditions.
Mahakali is the fierce cosmic power of dissolution, time, and ultimate reality. In Shaktism, she is a form of the Great Goddess (Mahadevi), dark, wild, and awe-inspiring, granting liberation through the destruction of ego and illusion.
Radha, by contrast, is the embodiment of pure devotion (premā-bhakti), the highest expression of Krishna's internal potency (antaranga shakti) in Vaishnavism. She signifies the soul's longing, unconditional love, and complete surrender to the Divine Beloved. Her form is radiant, graceful, and filled with the mood of ecstatic love.
For that reason, explaining "Radha" as a name of Mahakali would be theologically inaccurate in the traditional Hindu context, because it blends two distinct and deeply revered divine forms. Though both embody the Divine Feminine, their meanings, roles, and theological frameworks remain separate.
