An interest rate swaption or interest rate European swaption is an OTC option that grants its owner the right but not the obligation to enter an underlying interest rate swap. There are two types of swaptions: a payer swaption and a receiver swaption.
An payer swaption is also called a right-to-pay swaption that allows its holder to exercise into a swap where the holder pays fixed rates and receives floating rates, while a receiver swaption is also called right-to-receive swaption that allows its holders to exercise into a swap where the holder receives fixed rates and pays floating rates. This presentation gives an overview of swaption product and valuation. You can find more details at http://www.finpricing.com/lib/IrSwaption.html
