What is a Bond Yield?

A bond’s yield is the return to an investor from the bond’s coupon (interest) payments.
It can be calculated as a simple coupon yield, which ignores the time value of money, any changes in the bond’s price, or using a more complex method like yield to maturity.
What is a linker?
Daily inflation-indexed bonds (also known as inflation-linked bonds or colloquially as linkers) are bonds where the principal is indexed to inflation or deflation on a daily basis. They are thus designed to hedge the inflation risk of a bond.
