khói
/ˈsməʊkstæk//ˈsməʊkstæk/The word "smokestack" is a compound word, combining "smoke" and "stack." "Smoke" refers to the visible particles of combustion, which are released from chimneys. "Stack" refers to a structure built to support or hold something, in this case, a chimney. The term "smokestack" likely originated in the 19th century with the rise of industrialization and the use of steam engines. These engines produced vast amounts of smoke, which was expelled through tall chimneys known as smokestacks.
