in disorder, dangerous condition of the State
隉 centers on a state of instability and peril: disorder, upheaval, or a dangerous condition, especially of a state or government.
隉 combines ⻖ (mound, hill, or place) with a phonetic element that likely contributed the reading. The exact historical development of the right-side component is uncertain.
The left side ⻖ suggests a place or territory. The right side looks like a precarious stack of 臼 (mortar) over 工 (work), as if the state is a mortar balanced on unstable work—ready to fall into disorder.
For ゲツ, imagine a state in such disorder that people get sick from the chaos: 'gets' sick -> ゲツ. The dangerous condition makes everyone ill.
