Adya (आद्य, IAST: Ādya) is a Sanskrit-origin Hindu boy-name meaning “The primordial First, origin of all existence”. From ādi (beginning, origin) with the adjectival suffix -ya, Ādya names Vishnu as the absolute First Cause who precedes and underlies every created thing.

Meaning, etymology & significance

Rooted in the Sanskrit ādi, meaning the very beginning or primal source, Ādya conveys that Vishnu is not merely ancient but categorically prior to all else—the uncaused cause from whom time, space, and consciousness unfold. The suffix -ya transforms the noun into a quality, making him the one who is primordial by nature, not by sequence. This name resonates with Vedic cosmology, where the supreme reality is acknowledged before any other invocation.

Ādya is used as an epithet of Vishnu, Shiva, and the Goddess in various stotras, each tradition emphasizing the one First Principle in their own key. Pronounced AH-dya, with the ā long and the dya spoken as a single, soft syllable.
