+## Error handling
+
+Errors can be caught using `TEMPTA` (temptare = to try) and `CAPE` (capere = to catch). The `CAPE` block binds the error message to a variable as a string.
+
+```
+TEMPTA {
+  DESIGNA x VT I / NVLLVS
+} CAPE error {
+  DICE(error)
+}
+```
+
+```
+> Division by zero
+```
+
+If the try block succeeds, the catch block is skipped. If an error occurs in the catch block, it propagates up. `TEMPTA`/`CAPE` blocks can be nested.

 ## Functions
 Functions are defined with the `DEFINI` and `VT` keywords. The `REDI` keyword is used to return. `REDI` can also be used to end the program, if used outside of a function.
