What does flechette mean?
A flechette is a small, pointed steel dart designed as an anti-personnel projectile. Flechettes are rarely fired singly; instead they are dispersed in enormous numbers from exploding artillery shells, bombs, rockets, or canisters, turning each into a dense swarm of penetrating metal shards. The word derives from the French diminutive of flèche, meaning arrow, reflecting the weapon's dart-like form. Flechettes gained notoriety during the First World War, when aviators dropped them by the thousands over enemy positions, and they remain part of modern arsenals in the form of flechette rounds fired from tanks and shotguns. Strictly a technical and military term, it appears chiefly in weapons reporting, historical writing, and arms-control debate rather than everyday speech. Its vivid imagery — a storm of miniature arrows raining from the sky — makes it a striking example of how language preserves both the engineering and the brutality of warfare.
nounA small steel dart or projectile, typically fired in large numbers from a shell, bomb, or rocket, used especially as an anti-personnel weapon.
- A small steel dart dropped from aircraft or fired from shells, bombs, or rockets as an anti-personnel weapon.
- A similar dart-like projectile used in some firearms ammunition, such as flechette rounds fired from shotguns or experimental rifles.
"The shell burst overhead and released hundreds of flechettes that scythed through the air below."
"Pilots in the Great War scattered fleets of steel flechettes over enemy trenches before the era of reliable machine guns."
"The report examined injuries caused by flechette rounds fired during the urban engagement."
Standard English plural; flechette is a countable noun and the plural is used freely when describing quantities of the projectiles.
"Thousands of flechettes rained down on the trenches below."
A single artillery shell could scatter thousands of steel flechettes — tiny darts named after the French word for an arrow — making them one of the First World War's most feared aerial weapons.

Etymology of flechette
Flechette comes directly from French, where it is a diminutive of flèche, meaning 'arrow', formed with the -ette diminutive suffix; the French term was adopted into English military vocabulary around the time of the First World War, when flechette-dropping from aircraft became widespread. Flèche itself traces back through Latin flamma-related forms is incorrect — it derives from the Frankish *fliukka- or Germanic root underlying words like 'fly' and 'flee', the same Germanic source that gave English 'fletch', 'fletcher', and 'fledge'. Cognates therefore include English archery terms built on that same Germanic stem.
How flechette is actually used
Flechette is a technical term confined largely to military history and weapons reporting; it carries strongly violent connotations and is not used in everyday conversation. The plural 'flechettes' is standard. Because of its association with anti-personnel weaponry, the word appears mostly in journalism, arms-control discussion, and historical accounts.
Easily confused with flechette
Fletching refers to the feathers or vanes stabilizing an arrow, whereas a flechette is itself a small dart-like projectile.
