In the tradition of Hobson-Jobson , this dictionary contains Indo-English idioms and English words derived from Hindi. It serves as both a reference book and an interesting cultural examination of language and the postcolonial relationship between the British and Indians. Such words as dungaree , chintz , and lacquer are revealed as having a Hindi origin. Also included are entries on words tied to Hinduism such as guru , gherao , nirvana , asana , avatar , and mantra .
