I hate people who get drunk and then pick fights.
My hair got tangled around the button and I can't get it out.
Oh no! Sticky bubblegum got tangled around my fishing line! How can I get it out?
This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means entangle so the verb vocab version is to be entangled. This is when something is entangled on its own (you're not directly doing the entangling). You can remember this because of the む, which is you saying move (む) out of the way, I have to take care of this entanglement mess that just happened on its own.
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you: The entanglement mess you're fixing is a couple of kids that got their hair tangled up. They were doing some sparring in their からて class and one thing led to the other and suddenly both their hair was entangled together.
