What is the word pair that would best complete this analogy breach violation?

The word pair that best completes the analogy "breach : violation" is trespass : intrusion.

Here's why:

* Breach and violation both relate to breaking a rule, agreement, or boundary.

* Trespass and intrusion also relate to breaking a boundary, specifically physical boundaries.

The analogy works because both pairs represent actions that go against established rules or boundaries.
