entanglement
A messy tangle that is hard to separate or fix.
An entanglement is a complicated, confused mess where things are twisted or tangled together, making them difficult to separate. When you pull a necklace from your jewelry box and find it hopelessly knotted with two other chains, that snarl is an entanglement. When fishing line gets wrapped around itself dozens of times, fishermen call it an entanglement that can take forever to undo.
The word often describes situations that are just as messy as physical tangles. A person might find themselves in a legal entanglement when paperwork, lawsuits, and regulations become impossibly complicated. Countries sometimes face diplomatic entanglements when treaties and alliances create confusing obligations. If you promise to help three different friends with their projects on the same Saturday afternoon, you might find yourself in quite an entanglement trying to keep everyone happy.
Something becomes entangled when it gets caught up in a tangle. A bird might become entangled in a net, or a company might become entangled in complex regulations. The key idea is that once you're entangled, getting free takes real effort and patience. The more you struggle without thinking, the worse the tangle can become.
