Since Herodotus, the word
'India' has been taken from the term of the
river Sindhu (Indus River) which has been used in Greek (5th century BCE). The phrase first occurred in
Old English in the ninth century, and it reappeared in
Standard English in the seventeenth century.
In both formal and common usage, the
Republic of India is known in two short terms,
'India' and 'Bharata,'
both of which have a
rich history. The Indian Constitution's first provision declares that 'India, that is Bharat, should be a unity of kingdoms,' implying that 'India' and 'Bharata' (Hindi, written: Bharata) are both recognized short terms for India. When Indians communicate among themselves, a distinct appellation,
'Hindustan,' is frequently used as an alternate term for the country including most of the contemporary States of the country of the subcontinent.
The use of 'Bharata,' 'Hindustan,' or 'India' is dependent on the situation's environment and tongue.
The word 'Bharat,' which is used to refer to India in different
Indian languages, is claimed to be originated from either
Dushyanta's or Rishabha's son Bharata. The word Bharat was originally used solely to the western section of the
Gangetic Valley in North India, but it was eventually expanded to include the Indian subcontinent and the Greater India region, as did the name 'India.' It now refers to the modern
Republic of India, which is located there.
