La propietaria quiere cambiar el azulejo roto del baño.

Propietaria means female owner or female proprietor. In this sentence, it refers to a woman who owns the place or property.

Depending on context, English might translate it as:

• the owner
• the landlady
• the female property owner

Here, la propietaria is simply the female owner.

It is feminine because it refers to a woman.

You can see that in:

• la propietaria = the female owner
• el propietario = the male owner

Spanish often marks biological sex in nouns for people:

• propietario → masculine
• propietaria → feminine

The article changes too:

• la with feminine singular nouns
• el with masculine singular nouns

After querer (to want), Spanish normally uses a bare infinitive directly:

• quiere cambiar = wants to change
• quiere comer = wants to eat
• quiere salir = wants to leave

English uses to before the infinitive, but Spanish does not here. So:

• wants to change → quiere cambiar

Not quiere a cambiar.

Literally, cambiar means to change, but in this context it is often best understood as to replace.

So:

• cambiar el azulejo roto = change/replace the broken tile

In natural English, replace the broken tile sounds more idiomatic. But Spanish commonly uses cambiar in exactly this kind of situation.

Azulejo usually means a tile, especially a ceramic wall tile like the kind you find in kitchens or bathrooms.

In Spain:

• azulejo often suggests a wall tile
• baldosa is often used for a floor tile or paving tile

So in this sentence, el azulejo roto del baño most naturally means the broken bathroom tile.

In Spanish, descriptive adjectives usually come after the noun.

So:

• el azulejo roto = the broken tile

This is the normal order. Compare:

• la casa grande = the big house
• el vaso limpio = the clean glass

You can sometimes put adjectives before the noun in Spanish, but that often changes the tone or nuance. Here, azulejo roto is the standard and most natural order.

Del is the contraction of de + el.

So:

• de el baño → del baño

This contraction is required in normal Spanish.

Here, del baño means something like:

• of the bathroom
• from the bathroom
• more naturally in English: in the bathroom or the bathroom’s

So el azulejo roto del baño means the broken tile of the bathroom, which English would usually say as the broken bathroom tile or the broken tile in the bathroom.

It is singular because the sentence is talking about one broken tile.

• el azulejo roto = the broken tile

If it were more than one, it would be:

• los azulejos rotos = the broken tiles

So:

• La propietaria quiere cambiar el azulejo roto del baño.
• La propietaria quiere cambiar los azulejos rotos del baño.

Both are possible; the original just refers to a single tile.

Yes, but the meaning shifts slightly.

• el azulejo roto del baño = the broken tile of/from the bathroom, meaning the bathroom tile
• el azulejo roto en el baño = the broken tile in the bathroom

In this sentence, del baño identifies which tile it is: the one belonging to the bathroom area. That sounds very natural.

Using en el baño would focus more on location.

You could also say dueña, but the nuance is a little different.

• propietaria = owner, often a bit more formal or property-related
• dueña = owner, more general everyday word

So both can work, but propietaria fits very well if you are talking about a property owner or landlady.

For example:

• La propietaria quiere cambiar el azulejo roto del baño.
• La dueña quiere cambiar el azulejo roto del baño.

Both are understandable, but the first sounds slightly more specific/formal.

You would change the article and noun to masculine:

• El propietario quiere cambiar el azulejo roto del baño.

So:

• la propietaria = the female owner
• el propietario = the male owner

The rest of the sentence stays the same.
