To Break
To Snap, To Fracture
intransitive verb, ichidan verb
You already learned how 折る means "to fold something" or "to break something". This is the intransitive version of that, which just means it has no object. You just folded something too far, and now it's starting to break.
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You learned this reading when you learned 折る, so you should know this one too!
