URDU MEDIUM SCHOOL

I know the origins of the word Urdu:lashkar.

What I meant was that while there may be slang words being used it for a word to become part of the official language, there is some review. Eg whether a new word gets included in Oxford English Dictionary. If there are multiple. Words, sometimes one is picked, or more and some can be excluded, there is a process. Does Urdu have a similar process?
