01 · The full idiom, not the flashcard version
Me costó un ojo de la cara.
It cost me an arm and a leg.
The full idiom, not the vocabulary flashcard version — this is how it actually leaves someone's mouth.

Idiom Insider
Use real Spanish idioms — and paraphrase them in plain Spanish — out loud, in conversation.
Spanish idioms almost never translate word for word — costar un ojo de la cara is to cost an arm and a leg, ser pan comido is a piece of cake, and meter la pata is to put your foot in it. Never calque English idioms: it's llover a cántaros, not llover gatos y perros. And the same idea shifts by country — broke is estar sin blanca in Spain, sin un quinto in Mexico, no tener un mango in Argentina. At C1 the real skill is twofold: choosing the idiom that fits your audience, and paraphrasing it in plain Spanish when they don't know it.
Below: idioms by theme, how they change from Mexico to Argentina, the mistakes that give learners away — and a way to say them out loud in a real exchange, no flashcards, no matching exercises.
The warm-up pack
Idioms said whole, mid-sentence — never the bare dictionary entry.
01 · The full idiom, not the flashcard version
Me costó un ojo de la cara.
It cost me an arm and a leg.
The full idiom, not the vocabulary flashcard version — this is how it actually leaves someone's mouth.
02 · Describing someone who always says it straight
No tiene pelos en la lengua.
He doesn't hold back. (literally: "doesn't have hairs on the tongue")
Said about someone who always says exactly what they think — a compliment as often as a warning.
03 · A real complaint, not a dictionary entry
Estoy hasta las narices de esto.
I'm fed up with this.
A real complaint, not a vocabulary entry — say the whole sentence and you sound like you actually mean it.
04 · The weather complaint everyone shares
Está lloviendo a cántaros otra vez.
It's pouring rain again.
The standard way to complain about weather across the Spanish-speaking world — "cántaros" (jugs) instead of English's cats and dogs.
05 · The rejection you'd never guess from the words
Le dio el pavo anoche.
She turned him down last night. (Colombia, literally "gave him the turkey")
A rejection idiom you'll only get if someone explains it once — now someone has.
06 · Softer than saying someone messed up
Metió la pata en la reunión.
He put his foot in it at the meeting.
The go-to for describing an awkward mistake — softer and funnier than saying someone messed up.
07 · For someone stressing over nothing
Se ahogó en un vaso de agua.
They made a mountain out of a molehill. (literally: "drowned in a glass of water")
The perfect line for someone stressing over nothing — vivid, and everyone gets it instantly.
08 · The person who always goes all out
Tira la casa por la ventana en cada cumpleaños.
He spares no expense for every birthday.
Said about the person who always goes all out — generous, a little over the top, and everyone knows exactly who you mean.
09 · The compliment for getting it exactly right
Dio en el clavo con esa respuesta.
That answer hit the nail on the head.
The compliment for getting something exactly right — precise, and satisfying to say.
10 · Who's actually controlling the outcome
Tiene la sartén por el mango en esta negociación.
She has the upper hand in this negotiation.
Literally "holds the pan by the handle" — the person controlling the outcome, said with real edge.
11 · The sharp-eyed relative everyone has
No se le escapa una a mi abuela.
Nothing gets past my grandmother.
The idiom for someone with a sharp memory or sharp eyes — affectionate, and usually true.

Olivia
Your vocabulary teacher for this pack
There are no flashcards in the Idiom Insider pack and nothing to match up — you learn each idiom by saying it where it belongs. Olivia keeps setting you up: she asks about your week and you reach for estar hasta las narices; you describe a splurge with tirar la casa por la ventana; she gets your point exactly and you tell her she dio en el clavo. Then comes the C1 move: she plays someone who doesn't know the expression, and you paraphrase it in plain Spanish — out loud, mid-conversation, until the idioms stop being decoration and start being yours.
Blank mid-sentence and nothing bad happens — she waits. That's the practice, without unnecessary judgement.

Quick answers
Literally "to put the paw in" — it means to put your foot in it, to make a blunder. It's understood everywhere; in Argentina you'll also hear mandarse una macana for making a mistake.
Costar un ojo de la cara — to cost an eye from your face. In Mexico it often shortens to me costó un ojo.
Depends where you are. Spain: estar sin blanca. Mexico: estar bruja or sin un quinto. Argentina: no tener un mango. Colombia: estar pelado. Pick your region's version — the others may not land.
"To be eaten bread" — a piece of cake, something really easy. In Mexico you'll also hear es papita for the same thing.
Sparingly. Figurative language belongs in informal and semi-formal settings; in formal contexts, or with an audience from another region, give the plain-Spanish equivalent instead. Being able to paraphrase an idiom is exactly what this badge trains.
