According to Adi Shankara's commentary on the Vishnu sahasranama, Madhav means the consort of Ma, or Mahalaksmi, the Mother of the universe. Alternatively, it means one who is fit to be known through Madhu-vidya or can mean One who is the Lord of "Ma" or knowledge.
Additionally, it can also mean 'one who was born in the clan of Madhu'.
Madhava is another name for Vishnu or Krishna and appears as the 72nd, 167th and 735th names in the Vishnu sahasranama.
