Etymology

Origin of smokestack

First recorded in 1855–60; smoke + stack

Explanation

The chimney on top of a factory or a ship can be called a smokestack. If you look at Google Images for the word "pollution," you'll see lots of pictures of smokestacks spewing thick, gray smoke. The main difference between the words chimney and smokestack is that you're more likely to call the flue on top of your house a chimney, saving smokestack for more industrial uses. Steam locomotives used smokestacks to release smoke and steam — the exhaust from the train's smokebox. Without the smokestack, the pressure would become dangerously high inside the train, causing it to explode.
