👉 In the context of programming, "countersunken" refers to a condition where an object or variable has been marked as being untrusted (i.e., not properly validated) and cannot be trusted for further use. For example: ```python import sys def check(): # This line could potentially cause errors print("This is a counter-sunken value") ``` In this case, the `print()` statement will result in an error because it's marked as being untrusted
