The name comes directly from the Sanskrit word आदया (adya) meaning, “First, primitive, being at the beginning.”

It is also another name used for the goddess Shakti.

The name first appeared in the U.S. Top 1000 females under the form of Aadhya, coming in as the 953rd most popular female name in 2016. As of 2022, the name no longer appears in the U.S. Top 1000.

It should be noted that in Russian, Adya is a masculine diminutive form of Advey, which is the Russian form of the Biblical Hebrew (Obadiah).
