Wallah

Wallah, -walla, -wala, or -vala (Hindi: वाला)(-wali fem. वाली), is a suffix used in a number of Indo-Aryan languages, like Hindi/Urdu, Gujarati, Bengali or Marathi. Originating from Sanskrit पाल (pāla) + Middle Indo-Aryan -𑀓- (-ka-), it forms an adjectival compound from a noun or an agent noun from a verb. 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.
