enclosure, quarters, fortification, red-light district
郭 centers on a bounded, walled area: an enclosure, a fortified compound, or a designated quarter. The red-light district sense is a specific historical application of a walled-off entertainment quarter.
郭 combines 享 (a phonetic component suggesting a walled area) with ⻏ (the city wall radical), reinforcing the idea of an outer wall or enclosure around a settlement.
The left side 享 looks like a tall structure, and the right side ⻏ is a city wall. Picture a high-walled enclosure protecting the quarters inside.
For カク, imagine a cackling guard at the gate of the enclosure: cackle -> カク, and his laugh echoes off the fortification walls.
