Triveni Sangam
The word "prayāga" has been traditionally used to mean "a confluence of rivers". For Allahabad, it denoted the physical meeting point of the rivers Ganges and Yamuna in the city. An ancient tradition has it that a third river, invisible Sarasvati, also meets there with the two. Today, Triveni Sangam (or simply Sangam) is a more frequently used name for the confluence.
