Questa confezione sembra piccola, ma dentro c’è abbastanza pasta per tutti.

Because confezione is a feminine singular noun, so the demonstrative must agree with it.

• questa = this (feminine singular)
• questo = this (masculine singular)

So:

• questa confezione = this package

The same agreement happens with the adjective later:

• piccola matches confezione because it is feminine singular.

Confezione means something like package, pack, or packet, depending on context.

In this sentence, it refers to the container or packaged unit of pasta. It is a slightly general word, so in different situations Italian might also use words like:

• pacco = package / pack
• scatola = box
• pacchetto = packet / small pack

But confezione is very natural for food sold in packaging.

Sembra means seems or looks, while è means is.

So:

• è piccola = it is small
• sembra piccola = it seems small / it looks small

The sentence is saying that the package appears small, but actually there is enough pasta inside. So sembra creates that contrast.

Because adjectives in Italian usually agree with the noun they describe.

Here the noun is:

• confezione — feminine singular

So the adjective must also be feminine singular:

• piccola

Compare:

• un pacco piccolo = a small package/pack
• una confezione piccola = a small package

Literally, it means inside there is.

• dentro = inside
• c’è = there is

So:

• dentro c’è abbastanza pasta = inside there is enough pasta

In natural English, we would usually say there’s enough pasta inside.

Because pasta is treated as a singular mass noun in Italian.

• c’è = there is
• ci sono = there are

Since pasta is singular as a substance, Italian uses c’è:

• c’è pasta = there is pasta

If the noun were plural, you would use ci sono:

• ci sono due confezioni = there are two packages

Because c’è is a shortened form of ci è.

• the apostrophe shows that ci has been reduced before è
• the accent on è is part of the verb essere and distinguishes it from e meaning and

So:

• c’è = there is
• e = and
• è = is

This is very important in writing.

Here abbastanza means enough.

It comes before the noun:

• abbastanza pasta = enough pasta

It can also be used with adjectives and adverbs:

• abbastanza grande = big enough / quite big
• abbastanza bene = well enough / fairly well

With nouns, abbastanza often means enough very clearly:

• abbastanza acqua = enough water
• abbastanza tempo = enough time

Because Italian often omits the article with an uncountable noun when talking about a quantity in a general way, especially after words like abbastanza, molto, poco, and so on.

So:

• abbastanza pasta = enough pasta
• molta pasta = a lot of pasta
• poca pasta = little pasta

Using an article here would sound unnatural.

In Italian, pasta is usually an uncountable singular noun when it means pasta as food in general.

So Italian says:

• la pasta
• abbastanza pasta
• c’è pasta

Even if in English we are thinking of many pieces or servings, Italian still normally treats it as singular unless you are talking about different types of pasta in a more specialized way.

Per tutti means for everyone or for all of us/them, depending on context.

• per = for
• tutti = everyone / all

Here it means there is enough pasta to feed the whole group.

A useful detail: tutti is masculine plural in form, but it is also the normal mixed-group or generic form. If the group were entirely female, you could also hear per tutte.

Yes. Italian word order is flexible.

These are all possible, with slightly different emphasis:

• Dentro c’è abbastanza pasta per tutti.
• C’è abbastanza pasta dentro per tutti.
• C’è abbastanza pasta per tutti dentro. (less natural)

The original version puts dentro early, which highlights the contrast with the package seeming small on the outside.

No. In Italian, subject pronouns are often omitted because the verb form already shows the person and number.

Here the subject is understood from the context:

• Questa confezione sembra piccola

The subject is questa confezione, so there is no need to add a separate word for it.

Italian does this very often:

• È grande = It is big
• Sembra costoso = It seems expensive

The subject is often implied rather than stated again.
