South Asian English, informally Desi English, refers to English dialects spoken in most modern-day South Asian countries, inherited from British English dialect. Also known as Anglo-Indian English during the British Raj, the English language was introduced to the Indian subcontinent in the early 17th century. Today it is spoken as a second language by about 350 million people, 20% of the total population.
Although it is fairly homogeneous across the subcontinent, sharing "linguistic features and tendencies at virtually all linguistic levels", there are some differences based on various regional factors.
