Arunachalam – அருணாசலம்

Arunachalam (அருணாசலம்) is a traditional Tamil name that refers to the sacred Arunachala hill near Tiruvannamalai. The name combines elements often rendered as 'Aruna' (dawn or reddish) and 'achalam' (mountain), giving a sense of 'dawn/red mountain.' It evokes connection to the holy place or the qualities of sunrise—brightness, renewal and steadiness. Commonly used as a respectful masculine given name in South India.
