To Burn
To Be On Fire
intransitive verb, ichidan verb
Remember how 燃やす means "to burn something" or "to set on fire”? Well, 燃える is the version that means to burn or to be on fire. You might say that paper and wood 燃える easily, for example. And if your house is 燃えている, you're in trouble.
You can remember this slightly different meaning for 燃える because of the える part, which refers to the letter "L." And the "L" stands for "love" — as in your passionate, burning love for kanji.
The reading is the same as the word 燃やす.
これは燃えるゴミですか？燃えないゴミですか？
Is this burnable trash? Is it non-burnable trash?
これは燃えやすいから火のそばで使わないでください。
This is easy to burn, so please don't use it near fire.
なんか久々に燃えてきた！
I'm feeling really fired up for the first time in a long while!
