To Tear
To Rip, To Break
transitive verb, godan verb
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means tear so the verb version is to tear.
やぶる
You start to tear the cloth. You don't know if you're supposed to or not. The crowd isn't sure either. You hear kind of a yah boo (やぶ) reaction going on, making you unsure if you should continue or stop. Yah! Boo. Yah! Boo!
