Smoke
Smoke is a collection of airborne solid and liquid particulates and gases emitted when a material undergoes combustion or pyrolysis, together with the quantity of air that is entrained or otherwise mixed into the mass. It is commonly an unwanted by-product of fires (including stoves, candles, oil lamps, and fireplaces), but may also be used for pest control (cf. fumigation), communication (smoke signals), defensive and offensive capabilities in the military (smoke-screen), cooking (smoked salmon), or smoking (tobacco, cannabis, etc.). Smoke is used in rituals, when incense, sage, or resin is burned to produce a smell for spiritual purposes. Smoke is sometimes used as a flavoring agent, and preservative for various foodstuffs. Smoke is also a component of internal combustion engine exhaust gas, particularly diesel exhaust.

Famous quotes containing the word smoke:
“But when I don’t smoke I scarcely feel as if I’m living. I don’t feel as if I’m living unless I’m killing myself.”

“O women, kneeling by your altar-rails long hence,
When songs I wove for my beloved hide the prayer,
And smoke from this dead heart drifts through the violet air
And covers away the smoke of myrrh and frankincense;
Bend down and pray for all that sin I wove in song....”
—William Butler Yeats (1865–1939)
“All those large dreams by which men long live well
Are magic-lanterned on the smoke of hell;”
—William Empson (1906–1984)
