The word "Doab" is a combination of the Indo-Iranian words "Doab" ("two") and "āb" ("water"), and thus the (land of) "two rivers". The two rivers are the Beas and Sutlej. Sometimes, in English, there can be a definite article before the name i.e. "the Doaba". The name is also sometimes spelled as "Duoab" or "Douaab" or "Doaab".
