Common Mistakes

Avoid these frequent fire idiom pitfalls.

Saying "add oil to the fire" instead of fuel.

✓ Say "add fuel to the fire."

Explanation: The standard idiom uses 'fuel' (or wood). 'Oil' is sometimes used but is less standard in American English.

Tip: Think of wood or coal as the fuel for a fire.

Saying "burn the bridges" instead of burn bridges.

✓ Say "burn bridges."

Explanation: The plural 'bridges' is generally used without 'the', as it refers to all connections, not specific ones.

Tip: Keep it general: Don't burn bridges.

Saying "put fire out" instead of put out the fire.

✓ Say "put out the fire."

Explanation: The phrasal verb is 'put out'. Splitting it as 'put fire out' is less natural, though 'put the fire out' is acceptable.

Tip: Keep 'put out' together.

Saying "fire in the stomach" instead of belly.

✓ Say "fire in the belly."

Explanation: The established idiom uses 'belly', which evokes a deeper, more visceral drive than 'stomach'.

Tip: Remember 'belly' for determination.

Saying "flame in the pan" instead of flash.

✓ Say "flash in the pan."

Explanation: The idiom comes from the gun's pan flashing, not a flame. It refers to a brief spark of success.

Tip: Think of a quick flash of light, not a sustained flame.

Saying "on flames" instead of on fire.

✓ Say "on fire."

Explanation: When describing success, 'on fire' is the correct phrase. 'In flames' means failing.

Tip: Success = on fire. Failure = in flames.

Saying "strike the iron while it's hot" instead of strike while.

✓ Say "strike while the iron is hot."

Explanation: The idiom emphasizes the timing of the strike, not the action of hitting the iron itself.

Tip: Strike *while* the iron is hot.

Saying "make smoke" instead of smokescreen.

✓ Say "create a smokescreen."

Explanation: 'Smokescreen' is the specific noun for a distraction. 'Make smoke' sounds literal.

Tip: Use the noun 'smokescreen' for deception.

Saying "burn the candle on both ends" instead of at both ends.

✓ Say "burn the candle at both ends."

Explanation: The preposition 'at' is required to show where the candle is burning.

Tip: You burn a candle *at* both ends.

Saying "catch a fire" instead of catch fire.

✓ Say "catch fire."

Explanation: 'Catch fire' does not require an article. 'Catch a fire' sounds like catching a specific blaze.

Tip: Drop the 'a' for the idiom.
