History of the Punjabi language
Middle Indo-Aryan Languages are still synthetic like Old Indo-Aryan Languages but diphthongs and harsh combination of consonants were dropped, so much so that in the literary development these Prakrits became absolutely fluid. One poet said that the difference between Sanskrit poems and Prakrit poems is as great as between man and woman. Sankrit poems are harsh but Prakrit poems are very smooth.In 1837, British East India Company replaced Persian with Urdu in Punjab.
