Hello Dear,

Initially, there were 14 official languages. Now, there are 22 official languages in the 8th schedule of the Indian constitution.

Although the Official Language Act 1963 continued use of English as an official language in addition to Hindi still it is not recognized by the Eighth Schedule of the Constitution.

Though Pali and English are not part of the Eighth Schedule, these two languages were included by the UPSC in its scheme of examination long ago. Incidentally, over 2.2 lakh people had mentioned English as their mother tongue during the 2001 Census.

Good Luck hope it Helps!
