It combines the radical 火 (ひ) - fire, with the phonetic component 然 (ゼン/zen), which provides the sound and contributes to the meaning of "like that" or "as it is." The combination visually suggests fire (火) that is "like that" (然), thus depicting the action or state of burning. The upper part of 燃 is 然, whose components are 犬 (いぬ, dog) and 大 (だい, big). The bottom part is 火 (ひ, fire).
