Wallah, -walla, -wala, or -vala (-wali fem.), is a suffix used in a number of Indo-Aryan languages, like Hindi/Urdu, Gujarati, Bengali or Marathi. It forms an adjectival compound from a noun or an agent noun from a verb.[1] For example; it may indicate a person involved in some kind of activity, where they come from, or what they wear (topiwala), i.e., habitué.[2][3]
