Wallah
Wallah, or -wala or -vala ("wali" fem.), derived from Hindustani, Gujarati, Bengali or Marathi (Suffix forming an adjectival compound with a noun or an agentive sense with a verb), an Indian surname or suffix indicating a person involved in some kind of activity, where they come from or what they wear (Topiwala), for example:

* Rickshawala, a rickshaw driver
* Punkawallah, the servant who keeps the "punkah" or fan going on hot nights

"Wala" or "Vala" was also used in Parsi and Dawodi Bohra surnames, suggesting the profession or a place-name. For example:
*Amroliwala

*Mithaiwala, sweetseller 

Wala is also used to indicate a specific object or thing among several.

In British military jargon of the first half of the 20th century, a "base wallah" is someone employed at a military base, or with a job far behind the front lines.
