'Hinduistic' originates from 'Hindu,' which comes from the Persian word 'Hindū,' referring to the people and culture of the Indus Valley.

'Hindū' transformed into the English word 'Hindu,' and eventually the adjective form 'Hinduistic' was derived to describe characteristics related to Hinduism.

Initially, it referred to the people of the Indus Valley, but over time it evolved to describe the religion and culture associated with Hinduism.
