I am not interested to give very large explanation. So I am providing you actual definitions in short, If you still have any doubt then please let me know, I will explain you in my own language.
Test Scenario is a set of test cases that ensure that the business process flows are tested from end to end. They may be independent tests or a series of tests that follow each other, each dependent on the output of the previous one. The terms "test scenario" and "test case" are often used synonymously.
The scenario language is used to define the scenarios. Each scenario consists of a scenario name, the first word in a scenario, that may be followed by scenario elements. These elements may be simple elements or directives. Comments may also be included to describe the test scenarios and their purpose.
