貞吉

This phrase pairs a state of alignment or persistence (貞) with an evaluative outcome (吉). In divinatory and early philosophical contexts, 貞 functions as a technical term for steadfastness, correctness of position, or adherence to a proper course of action. The phrase typically operates in one of three modes:

1. Conditional: Steadfastness is the prerequisite for an auspicious result.

2. Descriptive: Success is rooted in proper alignment with the situation.

3. Verdictical: A summary judgment that a path is favorable provided the actor maintains their integrity or center.

The phrase usually functions as a compressed predicate lacking an explicit subject and verb; the agent and specific action must be derived from the surrounding context.

• 貞 vs. 正: While 正 (zhèng) typically refers to the correctness of position or status, 貞 emphasizes persistence or stability in that position.
• Contrast with 貞凶 (zhēn xiōng): The pairing of steadfastness with misfortune (凶) often implies a stubborn refusal to adapt when the situation demands change.

Avoid reducing 貞 solely to moral categories such as "virtue," "purity," or "chastity." In this pairing, the term refers more to structural or behavioral alignment. The resulting "luck" (吉) is presented not as a random windfall, but as the logical outcome of stability and correctness.
