- 2To cause a substance to combine with oxygen or another reactive agent, releasing heat; to oxidize.
The engine burns fuel, combining it with oxygen to release heat.

Note
Chemistry keeps the word but drops the flame. Iron can be burned in oxygen, and a human being is said to burn carbon with each breath, so respiration counts as slow burning. What matters to the chemist is a heat-releasing reaction, usually with oxygen though hydrogen can burn in chlorine, not visible fire.

Note
The figurative extension of fire, and it often takes up. Shakespeare's King John has "This tyrant fever burns me up", and Dryden's The Spanish Fryar (1681) has "This dry sorrow burns up all my tears". The particle adds a sense of completeness, of something used up entirely. Pepper, fever, envy and sorrow can all do the burning.

- 17An effective insult, especially a clever or cutting one.
Her reply landed as the sharpest burn of the night.
The crowd cheered after that savage burn.
Similardig, zinger, put-down, insult, diss
Oppositecompliment
Note
Slang's name for the insult that lands. Its signature phrase is sick burn, where sick praises rather than condemns: the speaker admires the cleverness, whoever the target was. Because it is slang, it belongs in banter and commentary rather than formal writing, where cutting remark or put-down does the same work.
- 18To insult someone, or to defeat them soundly.
He totally burned the other team in the debate.
Rivals love to burn each other on social media.
Similarroast, destroy, crush, trounce, own
Note
The verb behind the noun for a cutting insult, and just as slangy. It covers both the clever put-down and an outright win, so "I just burned you again" could follow a joke or a game. Keep it for casual talk; in formal writing, mock or defeat says the same thing.
- 19A scorch mark, hole, or other damage that fire or heat has made in something.
The landlord kept part of the deposit because of a cigarette burn in the carpet.
Sparks from the fireplace left tiny burns all over the rug.
Similarscorch
Note
Objects get burns the way skin does in the injury. Common compounds name the cause: cigarette burn, iron burn, burn mark. A scorch is lighter, a discoloration on the surface, while a burn may char right through, leaving a hole in a carpet or tablecloth that no cleaning will remove.

Similarbetray, double-cross, shop, grass
Note
Slang for betrayal, typically by someone who informs: the informant burned him. It is blunter and more conspiratorial than betray, and it belongs in informal speech. Its close relative in spy talk is exposing an agent's cover, where the damage done is to a hidden identity rather than to trust.
- 21To feel hot, often as a result of an emotion such as embarrassment.

UsageUsually with with for the cause: cheeks burning with shame, a forehead burning with fever.

- 22An intense emotional sting, such as the feeling left by shame or an effective insult.
The burn of public failure can linger for years.
Her cruel words left a burn he couldn't shake.
Similarsting, pain, hurt, wound
Note
The feeling an insult leaves behind, rather than the insult itself. It sits between the stinging sensation and the insult that causes it. If you say a remark left a burn, you mean the lingering sting. If the remark itself was a burn, you mean the insult. Both are slang, so they suit conversation better than formal prose.
- 23The process of writing data to a permanent storage medium such as a CD or ROM chip.
The burn failed halfway through, leaving the disc unusable.
If you run other heavy programs during the burn, the disc may end up with unreadable files.
Note
Computing turned the verb into a countable noun: a burn is one writing session, and discs can take more than one. Maria Langer's Mac OS X 10.2 Advanced (2002) explains that allowing additional burns creates a multisession CD that can be written to again. A burn can also fail midway, which is why the word is so often counted and checked.

- 24To make or produce something through the application of fire or intense heat.

In the hills above town, a few families still burn lime in stone kilns and sell it to local builders.
Note
Here fire makes rather than destroys: you burn a hole, burn letters into a block, burn charcoal. That last phrase is the trap. In H.L. Brækstad's translation of Asbjørnsen's Norwegian folk tales, men "had been burning charcoal", meaning producing it from wood. Burning charcoal on a grill consumes it instead, as in the plain destroying sense.

- 25To cauterize a wound or tissue, using heat to seal or destroy it.
The surgeon burned the edges of the cut to close it.
Doctors can burn abnormal tissue to keep it from spreading.
Note
Surgery borrows the everyday verb for cauterizing. The physical act matches the injuring sense, since heat is applied to tissue, but the intent is the reverse: the surgeon burns to seal or remove, not to harm. Only context tells you whether burned tissue was damaged or treated.

Heavier elements burn only when a star grows hot enough.
Similarfuse
Note
Astrophysics stretches the chemical sense past chemistry: an element burns in a star without oxygen or flame, by fusing into another element. The element is the subject and the product follows to, as in hydrogen burns to helium. The star can be the subject too, with the fuel as object: the Sun burns hydrogen.

Note
Spaceflight counts its burns. Jane's Space Directory (2004) logs a probe's second course-correction maneuver as a burn involving its four thrusters. The word is countable (a burn, two burns) and is scheduled and numbered like an event. It names the engine's work, not any fire on board.

The usual idiom is burn someone's cover, and the burning can be self-inflicted. In Thomas H. Cook's Night Secrets (1990), a man "had already burned his cover" through his own mistake. In Vanessa Kier's Vengeance (2013), the fear is that a superior burned an agent's cover on purpose. A burned agent is exposed, not merely let down.

Note
The darkroom's paradox is that more light makes the print darker, because an area darkens the longer it is exposed. Printers burn bright skies and edges to recover detail or steer the eye. The name carried over into video and digital editing, where darkening a region keeps the old darkroom verb.

- 30In Scottish and northern English use, a large stream.
We followed the burn down through the glen until it reached the loch.
After a week of rain the burn was running high and brown under the old stone bridge.
Note
A northern word with its own history: it comes from Old English burne, "spring, fountain", and is a separate word from the verb of fire. It carries the feel of hill country, from the "darksome burn" roaring down to the lake in Gerard Manley Hopkins's Inversnaid to James Kelman's Kieron Smith, Boy (2008), where after heavy rain the burn runs too wide to jump. Elsewhere, stream is the everyday word.

Word on the street was that the gang had a gun waiting and would burn him the minute he came back to town.
Note
A slang sense for shooting someone, at home in crime talk and best left there. Context matters, because in the same circles a person can also be burned in the betrayal sense. "They burned him" may point to a gun or to an informant, and only the surrounding story settles which.
- 32To blackmail a person, coercing them with threats to reveal damaging information.
Note
Intelligence jargon for blackmail. In John le Carré's Smiley's People (1979), Enderby asks "How does Leipzig burn him precisely? … What's the pressure?" The burning is the leverage itself: compromising material held over the target. That separates it from blowing an agent's cover, where the exposure has already happened.
