La pegatina del paquete está un poco torcida.

Because de + el normally contracts to del in Spanish.

So:

• de el paquete → del paquete

This is a standard contraction and is used almost all the time. The main common exception is when el is part of a proper name, such as de El Escorial.

Spanish often uses estar for a condition or state, especially something temporary or changeable.

Here, torcida describes the current position of the sticker: it is crooked / not straight right now. That is seen as a state, so está is the natural choice.

Compare:

• está torcida = it is crooked / wonky at the moment
• es torcida = this would sound odd here; it could suggest an inherent characteristic, which is not what you usually mean for a sticker stuck on badly

So for placement, position, appearance, or condition, estar is very common.

Because it agrees with pegatina, which is a feminine singular noun.

• la pegatina → feminine singular
• therefore torcida must also be feminine singular

If the noun were masculine, you would use torcido:

• el cartel está torcido

If it were plural:

• las pegatinas están torcidas

Here torcida means something like:

• crooked
• slanted
• askew
• not straight

In this sentence, it means the sticker has been placed a bit unevenly.

Be careful not to overthink it as literally “twisted.” In this context, it is the normal word for something visually not straight.

In Spain, pegatina usually means a sticker: something adhesive that you stick onto a surface.

Etiqueta usually means a label or tag. For a package, both might be possible depending on what you mean:

• pegatina = sticker
• etiqueta = label, shipping label, tag

If you are talking about the adhesive label attached to a parcel, etiqueta is also very common. Pegatina sounds more specifically like “sticker.”

Un poco means a little or slightly.

So está un poco torcida means:

• it is a little crooked
• it is slightly crooked

It softens the statement. Without it:

• La pegatina del paquete está torcida.

That sounds more direct: The sticker is crooked.

Because un poco modifies the adjective phrase and is naturally placed before the adjective in this kind of structure:

• está un poco torcida
• está un poco sucio
• está un poco rota

Putting it elsewhere is usually less natural. The normal word order is exactly what you see here.

La is the definite article, meaning the.

Spanish uses articles very regularly, often in places where English also uses them. Here it identifies a specific sticker:

• La pegatina del paquete = The sticker on the package

Without la, the sentence would be ungrammatical in this context unless you changed the structure completely.

Yes. Paquete can refer to a package, parcel, or packet depending on context.

In this sentence, del paquete most naturally means:

• of the package
• on the package
• attached to the parcel

English may choose different prepositions in translation, but the Spanish structure is very natural.

Yes, literally it is of the package.

But natural English often changes that relationship depending on context:

• The sticker of the package sounds unnatural
• The sticker on the package sounds better
• The package’s sticker is also possible

Spanish often uses de for relationships that English expresses in several different ways.

It is not the natural choice here. Spanish prefers estar because the sticker’s crookedness is about its current placement, not an essential characteristic.

So:

• está un poco torcida = natural
• es un poco torcida = odd in this context

A learner shortcut is:

• use estar for position, condition, and appearance that can change
• use ser for identity, classification, and more permanent characteristics

You would change the noun, article, verb, and adjective to match:

• Las pegatinas de los paquetes están un poco torcidas.

Changes:

• la → las
• del paquete → de los paquetes
• está → están
• torcida → torcidas

This is a good example of how much agreement Spanish uses.

Yes, it is common and natural. In Spain, for something physically misaligned, torcido/torcida works well.

You may also hear other words depending on context, such as:

• doblado = bent/folded
• inclinado = tilted
• mal puesto = badly positioned

But for a sticker that is stuck on crookedly, torcida is a very good choice.
