-The `try...catch...finally` statement defines one block of code to execute and test for possible errors, a second block of code to handle errors that may be present in the try block, and a third block of code to be executed regardless of the error status.
+The **`try...catch...finally`** statement defines three blocks of code. The `try` block contains code that is tested for possible errors. If an error occurs, the `catch` block handles the exception. Finally, the `finally` block contains code that will execute regardless of whether an error occurred, ensuring that cleanup or final actions take place.
 
-The `catch` and `finally` blocks of code are optional, but any `try` blocks must be followed by one or the other.
+All `try` blocks must be followed by either `catch`, `finally`, or both.
