Etymology and History:

The word "combustion" originates from the Latin "combustio," meaning "a burning," derived from "comburere" (to burn up). It evolved in English during the 15th century through scientific advancements, particularly with the study of fire and chemistry. In Thai, "การเผาไหม้" draws from native roots like "เผา" (to burn), influenced by modern scientific terminology introduced during the 19th-century Westernization.
