A typical definition of official language, such as by the Organisation for Economic Co-operation and Development is: 'A language that has legal status in a particular legally constituted political entity and that serves as a language of administration', for the country as a whole, one might add: India has 18 languages that are recognised by its constitution and can be considered as official, however the difference is that each language is recognised as the official language of a certain area e.g Kashmiri in Kashmir. The overall official language is Hindi, and this is what all central government decrees are written in, along with English. English is not considered an official language of the country, but rather a 'second language'. These languages (and area) are: Assamese (Assam), Bengali (West Bengal), Gujarati (Gujarat), Hindi (Bihar, Chandigarh, Delhi, Madhya Pradesh, Haryana, Himachal Pradesh, Rajasthan, Uttar Pradesh), Kannada (Karnataka), Kashmiri, Malayalam (Kerala), Manipuri, Marathi (Maharashtra), Nepali, Oriya (Orissa), Punjabi (Punjab), Sanskrit, Sindhi, Tamil (Tamil Nadu), Telugu (Andhra Pradesh), Urdu (Kashmir and Jammu), Konkani.
