Wallah is a noun used in South Asian English to denote a person associated with a particular role or service (e.g., conductor, seller, keeper). It is often appended to a root word to form a compound indicating a person who does or is associated with the thing, roughly translating to “one who does” or “person in charge.” In usage, it signals familiarity with the speaker’s social context and can carry affectionate or pejorative connotations depending on tone.
