When you refer to the index 0 of an array , you can speak the first element, right? Just as 1 is the second, 2 is the third, and so on. The 19th is the 20th.

How would you talk about the i element of the array ? i-esimo. So when you need to define a "generic" (variable) position of array , you can use this expression to indicate which element will depend on the value of i to know the actual position.
