+Define the following:
 
-- Recursion
-- Recursive Case
-- Base Case
-- Activation Chain/Stack
-- Activation Record/Call
-- Infinite Recursion/Stack Overflow/Stack too deep
-- Tail Recursion
+- Recursion - **The use of a method/application inside itself**
+- Recursive Case - **A problem that is divided into smaller problems**
+- Base Case - **An immediately solvable problem**
+- Activation Chain/Stack - **All of the iterations of the method being called within itself**
+- Activation Record/Call - **A single instance/iteration point of the method being called within itself**
+- Infinite Recursion/Stack Overflow/Stack too deep - **An error that occurs when the method results in an infinite loop**
+- Tail Recursion - **A type of recursion where the recursive call is the very last function of the method/operation**
