El pestillo del baño está un poco roto, pero todavía funciona.

Pestillo usually means a latch, bolt, or small sliding lock—the kind of thing you often use on a bathroom door for privacy.

It does not always mean a full lock in the broad English sense. Depending on the door hardware, related words could be:

• pestillo = latch / bolt
• cerradura = lock mechanism
• cerrojo = bolt / deadbolt

So in this sentence, pestillo suggests the bathroom door’s latch/bolt is a bit broken.

Because de + el contracts to del in Spanish.

So:

• de el baño → del baño

This is standard and required in normal Spanish.

A similar contraction is:

• a + el → al

For example:

• la puerta del baño = the bathroom door
• voy al baño = I’m going to the bathroom

Because roto describes a state or condition, not an essential characteristic.

• estar roto = to be broken
• ser would sound wrong here

So:

• El pestillo está roto = The latch is broken

This is a very common pattern in Spanish:

• está abierto = it is open
• está cerrado = it is closed
• está sucio = it is dirty
• está roto = it is broken

Even if something has been broken for a long time, Spanish still usually uses estar for that condition.

Because roto agrees with pestillo, which is a masculine singular noun.

• el pestillo → masculine singular
• so the adjective/participle is roto

Compare:

• El pestillo está roto.
• La puerta está rota.

The ending changes to match the noun’s gender and number:

• roto = masculine singular
• rota = feminine singular
• rotos = masculine plural
• rotas = feminine plural

Un poco means a little or a bit.

So:

• está roto = it’s broken
• está un poco roto = it’s a bit broken / slightly broken

It softens the statement and makes it less absolute. It suggests the latch is damaged, but not completely unusable.

That fits well with the second part:

• pero todavía funciona = but it still works

Here, todavía means still.

So:

• todavía funciona = it still works

It implies a contrast: the latch is damaged, but despite that, it continues to function.

In many contexts, todavía and aún can both mean still:

• Todavía funciona.
• Aún funciona.

Both are correct. Todavía is often very common in everyday speech.

Because Spanish often leaves out subject pronouns when they are clear from the verb or context.

In English, you need:

• it still works

In Spanish, the subject is already understood:

• todavía funciona

The implied subject is el pestillo.

You could say todavía funciona él, but that would sound unnatural here. Spanish normally avoids subject pronouns unless they are needed for emphasis or contrast.

Yes. Funciona is very natural for machines, devices, mechanisms, and anything that works/functions.

So:

• El pestillo funciona. = The latch works.

Other possibilities exist, but they mean slightly different things:

• sirve = works / is usable / does the job
• va = works, in a more informal way for devices in some contexts

In this sentence, funciona is the most straightforward and neutral choice.

Yes. That is perfectly correct.

• todavía funciona = still works
• aún funciona = still works

Both are natural. Todavía may sound a little more conversational to many learners because it is extremely common and easy to recognize, but aún is also standard.

Yes, it sounds natural.

A speaker in Spain would understand it easily. A few small vocabulary alternatives are also possible depending on the exact object:

• pestillo if it is a latch/bolt
• cerradura if you mean the lock itself
• cerrojo if it is more like a bolt

Also, in Spain, baño is common, though depending on the context people may also say:

• el baño
• el aseo
• el servicio

But in this sentence, del baño is completely normal.

Pero means but and introduces a contrast.

The two ideas are:

• está un poco roto = it’s a bit broken
• todavía funciona = it still works

These ideas pull in different directions, so pero is the natural connector:

• It’s damaged, but it still works.

Without pero, the relationship between the two parts would be less clear.

Yes. Roto is very commonly used for physical objects that are broken:

• El móvil está roto.
• La silla está rota.
• El pestillo está roto.

It can also be used figuratively in some contexts, but in everyday learner Spanish, the most important use is the literal one: broken.

So in this sentence, it simply means the bathroom latch is physically damaged.
