Mi madre guardó veinticinco euros en el monedero para el mercado.

In modern Spanish, you normally use the short possessive mi directly before the noun:

• mi madre = my mother
• mi padre = my father

Spanish does not usually say la mi madre in standard everyday language. That structure is old-fashioned or regional.

Also note that mi does not change for masculine/feminine:

• mi madre
• mi padre

But it does change in the plural:

• mis padres

Guardó is the preterite form of guardar for él/ella/usted.

Here it means something like:

• she put away
• she kept
• she stored
• she set aside

So Mi madre guardó... means My mother put away / set aside...

The preterite is used because the sentence describes a completed action in the past: your mother did it, and the action is presented as finished.

Conjugation of guardar in the preterite:

• yo guardé
• tú guardaste
• él/ella/usted guardó
• nosotros guardamos
• vosotros guardasteis
• ellos/ellas/ustedes guardaron

The accent mark shows both pronunciation and meaning.

• guardo = I keep / I am keeping
• guardó = he/she kept / put away

So the accent is important because it distinguishes:

• present tense yo guardo from
• preterite ella guardó

Without the accent, the word would mean something different.

In Spanish, the numbers from 21 to 29 are usually written as one word:

• veintiuno
• veintidós
• veintitrés
• veinticuatro
• veinticinco

So veinticinco euros is the normal spelling for twenty-five euros.

Some of these numbers have accent marks, but veinticinco does not.

Because the amount is more than one.

• un euro = one euro
• dos euros = two euros
• veinticinco euros = twenty-five euros

Spanish normally pluralizes currency nouns just like other nouns.

In Spain, monedero usually means a coin purse or small wallet/purse for money, especially one used for coins and small cash.

This can be a little different from English, because purse, wallet, and coin purse do not always match perfectly across languages.

In Spain:

• monedero = coin purse / small money purse
• cartera = wallet
• bolso = handbag

Depending on context, monedero here could mean a small purse where she keeps money.

En is the normal preposition for in here.

• en el monedero = in the purse/wallet

You would not use a because a usually indicates movement toward a place or a direct object with people.

• Guardó el dinero en el monedero. = She put the money in the purse.
• Fue al mercado. = She went to the market.

You could say dentro del monedero, but that is more explicit:

• en el monedero = in the purse
• dentro del monedero = inside the purse

In most ordinary contexts, en el monedero is the natural choice.

Spanish often uses the definite article el / la / los / las in places where English might not.

Here:

• en el monedero = in the purse/wallet
• para el mercado = for the market

Especially with common places, institutions, or specific known things, Spanish often prefers the article.

In this sentence, el mercado probably refers to the market as a known destination or purpose, not just the general idea of markets.

It means the money was being kept for the market, in other words, for going to the market / for buying things at the market.

So para here expresses purpose or intended use:

• dinero para el mercado = money for the market
• agua para la cena = water for dinner
• ropa para el invierno = clothes for winter

In natural English, you might translate it more freely as:

• for the market
• for shopping at the market
• to use at the market

This is a very common question.

Here, para is used because it shows purpose or destination:

• guardó veinticinco euros para el mercado
• She set aside twenty-five euros for the market.

Use para when something is intended for a purpose, recipient, or goal.

By contrast, por often means things like:

• because of
• through
• around
• in exchange for

Examples:

• Lo hice para ti. = I did it for you.
• Lo hice por ti. = I did it because of you / on your behalf.

So in this sentence, the idea is purpose: the money is intended to be used at the market. That is why para is correct.

Yes. Guardar is a flexible verb. Depending on context, it can mean:

• to keep
• to store
• to put away
• to save
• to set aside

In this sentence, likely meanings are:

• put away
• set aside
• saved/kept

Because of para el mercado, the idea is probably that she kept that money specifically for market shopping.

This is a very natural Spanish word order:

• Mi madre = subject
• guardó = verb
• veinticinco euros = direct object
• en el monedero = location
• para el mercado = purpose

Spanish word order is often flexible, but this neutral order is very common.

You could move parts around for emphasis, for example:

• Mi madre guardó en el monedero veinticinco euros para el mercado.
• Para el mercado, mi madre guardó veinticinco euros en el monedero.

But the original sentence sounds straightforward and normal.

Most likely it means a market in the everyday sense: a place where people buy food and other goods.

In Spain, ir al mercado often suggests going to a local market to buy fresh produce, meat, fish, etc.

So para el mercado most naturally means:

• for buying things at the market
• for the market trip
• market money

It is less likely to mean the market in an abstract economic sense.

Yes, but it would mean something slightly different.

• guardó veinticinco euros = she put aside / kept / stored twenty-five euros
• ahorró veinticinco euros = she saved twenty-five euros

Guardar focuses more on keeping or placing the money somewhere. Ahorrar focuses more on saving up money.

Because the sentence includes en el monedero, guardó is especially natural: it tells you where she put the money.

No. Standard Spanish says veinticinco.

For numbers from 31 onward, Spanish uses y:

• treinta y uno
• cuarenta y cinco
• cincuenta y dos

But 21–29 are special and are normally written as single words:

• veintiuno
• veintidós
• veinticinco
• veintinueve

So veinte y cinco is not the standard form.

Yes, it sounds natural and correct in Spain.

A speaker from Spain would understand it as something like:

My mother put twenty-five euros in her coin purse / wallet for the market.

The vocabulary is also very Spain-friendly, especially monedero and mercado in this kind of everyday context.
