loosen
This term describes the transition from a state of tension or rigidity to one of flexibility or ease. It carries a physical sense of releasing pressure, such as untying a knot or relaxing a muscle, and a systemic sense of reducing control, such as easing laws or regulations. In a social or political context, the word suggests a deliberate move toward leniency. It differs from "release" in that it implies the structure or rule still exists but is now less restrictive rather than being completely removed.
Meanings
