I really like burning things until they’re reduced to ashes.
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means burn and the verb vocab version is to burn something (or to burn).
This is when you're burning something. To remember this meaning, you have to remember the も part. So, just think of your friend Moe (も), and how you're going to burn him... uh... just a little bit.
