Colour idioms
| Idiom | Meaning |
|---|---|
| A white elephant | a possession that is costly to keep but useless |
| A black sheep | the disgraced or disreputable member of a group |
| Once in a blue moon | very rarely, almost never |
| A red-letter day | an important day worth remembering |
| See red | become suddenly very angry |
| Red tape | excessive official rules and delays |
| Out of the blue | completely unexpectedly |
| A grey area | a matter unclear in law or morality |
| Green with envy | strongly jealous |
| Born with a silver spoon in one's mouth | born into a rich family |
Colour logic: white → useless-grand (white elephant), black → disgrace (black sheep), blue → unexpected (once in a blue moon, out of the blue, bolt from the blue), red → anger/officialdom (see red, red tape, red-letter day is the exception — a day marked in red ink, hence memorable), green → envy, grey → unclear, silver → inherited wealth.
Food idioms pair an eating image with an abstract judgement: easy (piece of cake), stubborn (hard nut), flattery (butter up), thought (food for thought), cherished (apple of the eye), secret (spill the beans), exaggeration (mountain of a molehill), useless supply-shifting (coals to Newcastle), trivial storm (storm in a teacup), controversy (hot potato).
Food idioms
| Idiom | Meaning |
|---|---|
| A piece of cake | a task needing almost no effort |
| A hard nut to crack | a stubborn problem or a difficult person |
| The salt of the earth | a thoroughly good and dependable person |
| Butter someone up | flatter someone for one's own gain |
| Food for thought | something that deserves serious thinking |
| Cry over spilt milk | waste regret on what cannot be undone |
| In a pickle | in an awkward difficulty |
| The apple of one's eye | a person cherished above everyone else |
| Spill the beans | divulge a secret |
| A hot potato | a touchy issue everyone avoids handling |
| Add fuel to the fire | make an angry situation worse |
| Make a mountain of a molehill | blow a trivial matter out of proportion |
| Carry coals to Newcastle | supply something to a place that already has plenty |
| Set the Thames on fire | achieve something sensational (usually said in the negative) |
Close pairs inside these banks: 'spill the beans' (reveal a secret) vs 'cry over spilt milk' (vain regret); 'a white elephant' (costly, useless) vs 'the lion's share' (the biggest part); 'red tape' (official delay) vs 'red-letter day' (memorable day). The exam draws options from inside these pairs — learn each pair as a unit.
Detailed notes
Colours carry feelings
In English idioms each colour usually carries the same feeling. Learn the colour and you know the family of the meaning.
| Colour | Usual meaning | Idiom | Meaning |
|---|---|---|---|
| blue | unexpected, rare | out of the blue | suddenly, without warning |
| red | anger, officialdom, special day | see red / red tape / red-letter day | become angry / official delay / a day to remember |
| green | envy, jealousy | green with envy | very jealous |
| black | disgrace | a black sheep | the one who brings shame to a family |
| white | costly and useless | a white elephant | expensive to keep but of no use |
| grey | not clear | a grey area | a matter that is not clearly right or wrong |
| silver | wealth, hope | born with a silver spoon | born in a rich family |
Worked use: The new flyover that nobody uses but costs lakhs to maintain is a white elephant. White = costly-useless. Meaning: a possession that costs much but gives no benefit.
Watch out for red. Red has three different families. See red = angry. Red tape = too many official rules causing delay (government files were once tied with red ribbon). Red-letter day = a happy, important day (special days were marked in red on calendars). Examiners put these three against each other.
Food idioms are judgements
Food idioms use something we eat to give a judgement about a task or a person.
| Idiom | Judgement | Meaning |
|---|---|---|
| a piece of cake | easy | a very easy task |
| a hard nut to crack | difficult | a difficult problem or person |
| butter someone up | flattery | praise someone to get a favour |
| food for thought | thinking | something worth thinking about |
| a hot potato | controversy | an issue everyone avoids handling |
| in a pickle | trouble | in a difficult situation |
| the apple of one's eye | love | the person loved most |
| spill the beans | secret | reveal a secret |
| the salt of the earth | goodness | a very good, honest person |
| carry coals to Newcastle | useless supply | take something where it is already plentiful |
| a storm in a teacup | fuss | a big quarrel over a small matter |
Worked use: Maths is a piece of cake for Arjun. Cake = easy. So maths is very easy for him.
Look-alike pairs in this bank
- The apple of one's eye (most loved) vs the apple of discord (cause of a quarrel).
- A piece of cake (easy) vs a hot potato (a touchy issue).
- Red tape (delay) vs red-letter day (happy day).
- Born with a silver spoon (rich from birth) vs every cloud has a silver lining (some good in every bad situation).
Fill-in-the-blank use
Sometimes a sentence has a blank and four idioms as options. First decide what the sentence needs: a useless thing? a small fuss? a happy day? Then pick the idiom from that family. Check grammar too — was ___ for her family needs a noun phrase such as a red-letter day.
Quick revision
- Blue = sudden/rare; red = anger, delay or a special day; green = envy; black = shame; white = costly-useless; grey = unclear.
- Food = judgement: cake easy, nut hard, butter flatter, potato touchy, pickle trouble, apple loved.
- Learn the look-alike pairs together.
- In blanks, decide the need first, then the family, then check grammar.
Types of questions asked
Every way this subtopic shows up in exams — how to recognise it, the formula or logic to use, and a solved example.
Type 1: Meaning of a colour idiomvery common3 practice Q
The idiom contains a colour word: blue, red, green, black, white, grey, silver.
- Recall the colour's usual feeling (blue = sudden, green = envy).
- Read the rest of the idiom to choose inside that family.
- Reject options that treat the colour literally (paint, clothes, sky).
Why it works: colour idioms share stable associations across English.
Example: Meaning of Out of the blue: (a) from the sky (b) suddenly and unexpectedly (c) very sad (d) far away
Blue = unexpected. Answer: (b) suddenly and unexpectedly. 'From the sky' is the literal decoy.
Type 2: Meaning of a food idiomvery common3 practice Q
The idiom names a food item: cake, nut, butter, potato, pickle, beans, milk, apple, salt.
- Turn the food into a judgement (cake = easy, nut = hard).
- Pick the option with that judgement.
- Drop options about cooking, eating or prices.
Why it works: food idioms always judge a task, a person or a situation.
Example: Meaning of Food for thought: (a) a healthy diet (b) something worth thinking about (c) a free meal (d) a boring lecture
The 'food' feeds the mind. Answer: (b) something worth thinking about.
Type 3: Colour or food idiom with a look-alike twincommon3 practice Q
One option is the meaning of a twin idiom sharing the colour or food word (red tape vs red-letter day; apple of one's eye vs apple of discord).
- Spot the shared word.
- Recall both twins and their meanings.
- Choose the meaning of the stem idiom only.
Why it works: the twin's meaning is planted because it feels familiar.
Example: Meaning of Born with a silver spoon in one's mouth: (a) hopeful in hard times (b) born in a rich family (c) fond of good food (d) very talkative
'Hopeful in hard times' is the twin (silver lining). Answer: (b) born in a rich family.
Type 4: Fill the blank with a colour or food idiomcommon3 practice Q
A sentence with a blank; four idioms as options.
- Decide what the blank needs (a useless thing, a fuss, a happy day, a useless supply).
- Pick the idiom from that meaning family.
- Read the full sentence once to check grammar and sense.
Why it works: the sentence is written so that only one idiom's meaning fits.
Example: The huge statue that costs lakhs to maintain but draws no visitors has become a ___. (a) white elephant (b) black sheep (c) red-letter day (d) piece of cake
Costly + useless → (a) white elephant.
Shortcut tricks
⚡ Colour association
Blue = surprise, red = anger or bureaucracy, green = envy, white = useless grandness, black = disgrace. Half the colour idioms decode from this alone.
⚡ Food-judgement fit
Food idioms are judgements in disguise: cake→easy, nut→stubborn, pickle→difficulty, potato→controversy. Match the judgement, not the ingredient.
⚡ Pair-learning
Learn confusable idioms in pairs on one card: beans/milk, elephant/lion's share, red tape/red-letter day. The option list usually contains both members.
Where students lose marks
Reading 'red-letter day' negatively because 'red' suggests danger.
Taking 'hot potato' to mean a tasty offer instead of a touchy issue.
Mixing 'in a pickle' (awkward spot) with 'in a nutshell' (in brief).
Confusing 'born with a silver spoon' (rich) with 'every cloud has a silver lining' (hope in trouble).
