The name Tanisha has its origins in Sanskrit, an ancient Indo-Aryan language that dates back to the 2nd millennium BCE. It is believed to be derived from the Sanskrit word "tanu," meaning "body" or "slender," and "isha," which translates to "lord" or "master." The name's roots can be traced back to the Indian subcontinent, where Sanskrit was the literary language of ancient India.
