Thrinay
Thrinay is a word from sanskrit language. It has multiple meanings. Trina means throne in sanskrit. The word Thrinay means one who is seated on throne. It is mainly used to describe Gods and Goddesses in Hindu religion. It is used more in Devi Mahatmya to address Saraswati, one of the three supreme goddesses of Hindu religion. In some Puranas (like Skanda Purana) Saraswati is considered the daughter of Shiva (Shivaanujaa) and in some Tantras she is associated with Ganesha as his sister.
Some also consider Thrinay as one of the names of Lord Shiva.
