abstain

This word conveys a sense of conscious, disciplined restraint. It is typically used when the subject is resisting a temptation or adhering to a moral, religious, or health-related code. The tone is formal and implies a deliberate act of will rather than a passive lack of action.

In political or parliamentary contexts, it describes a specific neutral stance. Choosing to abstain in a vote is a formal procedural act that differs from simply being absent, as it explicitly records a decision not to support or oppose a motion.
