To circumscribe is to limit or restrict. If you spend too much time watching TV instead of fulfilling other obligations, you might circumscribe your TV-watching time to one hour daily (or two hours, if your favorite show is on)
demanding strict attention to rules and procedures (Stringent safety procedures prevent accidents in a dangerous work environment. And restaurants must adhere to stringent health regulations)
When you're indignant, you're angry about an unfair situation. If you discovered that a teacher gave ten extra points on a test to all students who sat in the front row, you'd be indignant.
