Common Mistakes

Avoid these frequent idiom pitfalls.

Saying "dodge a gun" instead of a bullet.

✓ Say "dodge a bullet."

Explanation: The idiom relies on the projectile (the bullet) being the danger you narrowly avoid, not the weapon itself.

Tip: You dodge the fast-moving bullet, not the gun.

Spelling "take the flak" with a 'c' (flack).

✓ Spell it "flak."

Explanation: 'Flak' is an acronym for the German word Fliegerabwehrkanone. 'Flack' with a c refers to publicity agents.

Tip: Remember it's a military acronym without a 'c'.

Saying "stick to your gun" in the singular.

✓ Say "stick to your guns."

Explanation: Naval batteries consisted of multiple guns. The idiom requires the plural to represent holding your entire position.

Tip: You defend multiple guns, not just one.

Saying "hold the castle" instead of the fort.

✓ Say "hold the fort."

Explanation: The idiom comes from frontier military outposts, which were small 'forts', not massive castles.

Tip: Think of a small wooden fort, not a stone castle.

Saying "drop a bomb" instead of a bombshell.

✓ Say "drop a bombshell."

Explanation: A 'bomb' is the weapon, but a 'bombshell' specifically refers to the shocking, explosive impact of the news.

Tip: It's the 'shell' that delivers the shock.

Saying "friendly shooting" instead of friendly fire.

✓ Say "friendly fire."

Explanation: The standard military idiom for accidental attacks on allies uses the word 'fire', not 'shooting'.

Tip: Always use 'fire' in this idiom.

Saying "call the shot" in the singular.

✓ Say "call the shots."

Explanation: Being in charge means making multiple decisions, so you call multiple 'shots' over time.

Tip: Bosses make many decisions (shots).

Saying "in the crosshair" instead of the plural.

✓ Say "in the crosshairs."

Explanation: A sniper scope has intersecting lines (plural crosshairs) that form the targeting reticle.

Tip: There are multiple lines forming the cross.

Saying "shoot down in fire" instead of flames.

✓ Say "shoot down in flames."

Explanation: The idiom relies on the imagery of a destroyed plane falling in literal flames.

Tip: Planes go down in flames, not just fire.

Saying "fight a loosing battle" with two o's.

✓ Say "fight a losing battle."

Explanation: The word is 'losing' (from lose), meaning you are failing. 'Loosing' means setting something free.

Tip: Remember it's about losing, not loosing.
