India's linguistic picture is complex. According to the [[Constitution of India]], "[[Hindi]] in the [[Devanagari]] script" is the official language of the union; and English the 'subsidiary official language'; however, English must be used for the official texts of all federal laws and Supreme Court decisions (with Hindi). It is one of the two languages of the [[Lok Sabha|Indian Parliament]]. English is taught in schools. The quality and effectiveness of the teaching is very varied. English is used almost exclusively for higher education.
