stoker

A stoker is usually the person who feeds fuel, often coal, into a furnace or boiler to keep a fire burning. The word brings to mind the hard, dirty work that kept steamships, trains, and old factories running. In another common use, especially in cycling, the stoker is the rider on the back seat of a tandem bicycle, working together with the front rider to keep the bike moving.

The word "stoker" began in the world of fire, heat, and heavy labor. Its core meaning is a person who tends a furnace, boiler, or engine fire by adding fuel and keeping it burning at the right level. In the age of steam, this was exhausting work. On ships, trains, and in factories, the stoker helped keep the whole system alive, feeding coal into the fire so that power would not fail. The word still carries that image of soot, heat, and steady physical effort.

Over time, the word found another well-established home in cycling. On a tandem bicycle, the stoker is the rider in the rear position, behind the person steering in front. The front rider guides the bike, while the rear rider adds power and rhythm. In that setting, the word keeps its old sense of helping drive something forward, even though the fire is gone.

You may also see "stoker" used more loosely for someone who stirs up feeling or trouble, as in a person who keeps anger, fear, or conflict burning. That figurative use exists, but it is less central than the industrial and cycling meanings. Most of the time, the word points either to the worker who tended the fire in older machinery or to the back rider on a tandem bike.
