La vicina ha promesso che mi avrebbe riportato il colino dopo aver finito di condire l’insalata di cetriolo.

In Italian, common nouns usually take an article when you mean a specific person or thing. So la vicina means the neighbor.

Here, vicina is feminine singular, so the article is la.

• il vicino = the male neighbor
• la vicina = the female neighbor

Italian uses articles more often than English, so leaving it out would usually sound incomplete here.

Ha promesso is the passato prossimo, formed with:

• ha = present of avere
• promesso = past participle of promettere

So ha promesso means promised / has promised, depending on context. In this sentence, it refers to a completed past action: she made the promise.

Because the promise itself is already in the past: ha promesso. After a past reporting verb like promised, Italian often uses the conditional past to express a future action viewed from that past moment.

So:

• ha promesso = she promised
• avrebbe riportato = she would bring back

This is often called future in the past.

A rough comparison:

• Promette che me lo riporterà = She promises that she will bring it back to me.
• Ha promesso che me lo avrebbe riportato = She promised that she would bring it back to me.

It is the condizionale passato of riportare.

It is formed with:

• avrebbe = conditional of avere
• riportato = past participle

So:

• riporterebbe = would bring back
• avrebbe riportato = would have brought back / would bring back, depending on context

In this sentence, it does not mean a contrary-to-fact idea like English would have sometimes does. It is mainly being used for future in the past after ha promesso.

Mi is an indirect object pronoun meaning to me.

So:

• mi avrebbe riportato il colino = she would bring the strainer back to me

Italian often uses these short object pronouns where English might say to me, to him, to us, etc.

Other examples:

• mi parla = he/she speaks to me
• ti scrivo = I write to you
• ci manda un messaggio = he/she sends us a message

In Italian, unstressed object pronouns like mi, ti, gli, le, ci, vi usually come before the conjugated verb.

So you get:

• mi avrebbe riportato
• ti direi
• gli ha telefonato

That is the normal position with finite verbs. English speakers often want to place it later because English says bring back to me, but Italian prefers the pronoun before the verb.

Here riportare means to bring back.

• portare = to bring, carry
• riportare = to bring back

So mi avrebbe riportato il colino is literally something like would have brought the strainer back to me.

It is similar to restituire (to return, give back), but riportare emphasizes the physical act of bringing it back. In everyday speech, both could work in many contexts, but riportare feels very natural for returning an object someone borrowed.

Both are possible. Aver is just the shortened form of avere before another word, especially in common structures like this.

So these both mean the same thing:

• dopo aver finito
• dopo avere finito

The shorter form is very common and sounds natural.

Italian often uses dopo + infinitive when the subject is the same as the subject of the main clause.

Here, the understood subject of aver finito is the same person as la vicina. So the sentence means:

• The neighbor promised that she would bring me back the strainer after she had finished dressing the cucumber salad.

Using the infinitive avoids repeating the subject.

If you wanted a full clause, you could say something like:

• dopo che aveva finito di condire l’insalata di cetriolo

But the infinitive version is more compact and very natural.

The understood subject is la vicina.

So the sentence naturally means that the neighbor would return the strainer after the neighbor finished dressing the cucumber salad.

This is a very common feature of Italian infinitive clauses: the subject is often not stated because it is understood from the context.

Because finire is commonly followed by di + infinitive when it means to finish doing something.

So:

• finire di leggere = to finish reading
• finire di mangiare = to finish eating
• finire di condire = to finish dressing/seasoning

This is just the normal pattern of the verb.

Condire means to season, to dress, or to add dressing/condiments to food.

With salad, English often says to dress a salad. So:

• condire l’insalata = to dress the salad

It usually refers to adding things like oil, vinegar, salt, pepper, lemon juice, and similar ingredients.

Because la becomes l’ before a vowel. This is called elision.

So:

• la + insalata → l’insalata

The apostrophe shows that the final vowel of la has been dropped.

In Italian, after di to indicate the main ingredient or type of dish, the ingredient is often left in the singular.

So:

• insalata di cetriolo = cucumber salad
• zuppa di pomodoro = tomato soup
• succo di mela = apple juice

This is very normal. Italian is describing the kind of salad, not counting individual cucumbers.

Because it refers to a specific, identifiable object: the strainer.

Italian normally uses the definite article in situations where English also would, and often even a bit more broadly. Here, both languages naturally use it because the speaker and listener presumably know which strainer is meant.

• un colino = a strainer
• il colino = the strainer

It is most naturally linked to the returning.

So the idea is:

• she promised
• that she would return the strainer
• after finishing the salad

In other words, after finishing the cucumber salad tells us when she would bring back the strainer, not when she made the promise. Context could theoretically affect interpretation, but the default reading is that the finishing happens before the returning.
