arbitrary

This word carries a strong sense of unpredictability and a lack of logical grounding. When used in a casual or scientific context, it suggests a random selection made for convenience, such as picking an arbitrary number to start a test. It implies a void of justification, where the choice could have just as easily been something else. In legal or political contexts, the word takes on a more sinister, oppressive tone. Here, it describes the exercise of power that ignores established rules or fairness. It evokes a feeling of helplessness in the face of a whim, where the outcome is determined by the mood of a superior rather than a transparent process.
