The word 点燃 is formed by combining two characters, each contributing an essential action to create a unified concept. The first character, 点 (diǎn), carries the meaning of touching to a point or initiating a spark, as in lighting a match. The second, 燃 (rán), means to burn or be aflame. When placed together, they depict a sequential, cause-and-effect process: the initial act of kindling (点) directly leads to the sustained state of combustion (燃), perfectly capturing the complete action of "to ignite" or "to light something on fire".
