La guardería tiene un patio grande donde las niñas dejan cada juguete en su sitio después de jugar.

In Spain, guardería usually means a daycare centre or nursery school for very young children.

A few notes:

• In Spain, guardería is very common for a place where small children are looked after during the day.
• In English, nursery can overlap in meaning, but it is not always a perfect match depending on the country.
• A slightly broader modern term you may also see is escuela infantil.

So in this sentence, la guardería means the daycare / nursery.

Spanish often uses the definite article more than English does.

Here, la guardería means:

• the daycare centre
• the specific daycare being talked about

English might sometimes say The daycare has..., and Spanish does the same with la.

Leaving out the article here would sound unnatural in a normal sentence.

Because most descriptive adjectives normally come after the noun in Spanish.

So:

• un patio grande = a big playground/courtyard

This is the normal order:

• noun + adjective

Using grande before the noun is possible in some cases, but it often sounds more literary, emphatic, or changes the nuance. In everyday Spanish, un patio grande is the natural choice.

Not exactly.

In Spanish, patio can mean:

• a courtyard
• a play area
• an open space inside or attached to a building

In a school or daycare context, patio often means the playground or outside area where children play.

So here, un patio grande is probably best understood as a big playground / outdoor play area, not just a patio in the English home-garden sense.

Donde means where and introduces a clause that describes patio.

So:

• un patio grande donde las niñas dejan cada juguete en su sitio... = a big playground where the girls leave each toy in its place...

It connects the place (patio) with what happens there.

Because here it is a relative word, not a question word.

• donde = where in a statement
• dónde = where? in a direct or indirect question

Compare:

• Es el lugar donde juegan. = It’s the place where they play.
• ¿Dónde juegan? = Where do they play?

So in your sentence, no accent is needed.

Yes, las niñas means the girls.

Breakdown:

• las = the (plural feminine)
• niñas = girls

Spanish nouns have grammatical gender, and niña is feminine singular. Its plural is niñas.

If the group were boys, it would be:

• los niños

If it were a mixed group, Spanish often uses:

• los niños or a more inclusive wording depending on context.

Dejan is the third person plural present tense of dejar.

Dejar can mean:

• to leave
• to put
• to place depending on context

Here, las niñas dejan... means:

• the girls leave / put ...

Because the subject is plural (las niñas), the verb must also be plural:

• la niña deja = the girl leaves
• las niñas dejan = the girls leave

The present tense here expresses a general fact or a habitual action.

So the sentence is not necessarily about what is happening right now at this exact second. It can mean:

• the daycare has a big playground
• the girls usually put each toy back in its place after playing

Spanish uses the present tense this way very often, just like English does in sentences such as:

• The school has a playground.
• The children put the toys away after playing.

Cada juguete means each toy.

Spanish uses cada + singular noun:

• cada juguete
• cada niña
• cada día

So even though the meaning involves many toys, the noun after cada stays singular.

Difference:

• cada juguete = each toy individually
• todos los juguetes = all the toys as a group

Here, cada juguete emphasizes that they put away every single toy properly.

En su sitio means in its place or where it belongs.

This is a very common expression in Spanish:

• poner algo en su sitio = to put something in its place
• dejar algo en su sitio = to leave something where it belongs

It can refer to:

• physical order and tidiness
• the correct place for an object

So in this sentence, it means the girls put each toy back where it belongs.

Yes, su can mean all of those depending on context:

• his
• her
• your (formal singular)
• its
• their

That is very normal in Spanish. Context tells you which meaning is intended.

Here, cada juguete en su sitio is understood as:

• each toy in its place

Spanish does not usually have a separate everyday possessive word exactly like English its. Instead, su often does that job.

Because the phrase is understood one toy at a time:

• cada juguete en su sitio = each toy in its place

With cada, Spanish focuses on each individual toy separately, so singular su sitio makes sense.

If you said todos los juguetes en sus sitios, that would mean:

• all the toys in their places

That is also correct, but it is a slightly different structure and emphasis.

Because after después de, Spanish normally uses:

• a noun, or
• an infinitive

So:

• después de jugar = after playing

This is very common:

• después de comer = after eating
• después de estudiar = after studying
• después de trabajar = after working

Using the infinitive after de is the standard structure here.

Because after después de, the verb goes in the infinitive, not a conjugated form.

So:

• después de jugar = correct
• después de juegan = incorrect

Think of it like English:

• after playing not
• after they play in this structure

If you wanted a full clause, you would need a different structure, for example:

• después de que juegan is generally not the normal choice here
• more natural would be después de jugar

Yes. You could also say:

• La guardería tiene un patio grande en el que las niñas dejan cada juguete en su sitio después de jugar.

This means the same thing.

But:

• donde is simpler
• donde is more natural in everyday speech when referring to a place

So donde is the most straightforward and natural option here.

Both can work, but they are slightly different in feel.

• dejar here suggests leaving/putting something somewhere
• poner means more directly to put

So:

• dejan cada juguete en su sitio = they leave/put each toy in its place
• ponen cada juguete en su sitio = they put each toy in its place

In many contexts, both are acceptable. Dejar sounds very natural when talking about returning things to where they belong.

Yes, it sounds natural and correct.

It has a very typical Spanish structure:

• La guardería tiene... = the daycare has...
• un patio grande = a big playground/courtyard
• donde... = where...
• las niñas dejan cada juguete en su sitio = the girls put each toy back in its place
• después de jugar = after playing

A native speaker would understand it easily, and it sounds like normal descriptive Spanish.
