Questions & Answers about La pressione di estrazione cambia con la pressatura.

Why are there two la's in the sentence?

Because both pressione and pressatura are singular feminine nouns.

• la pressione = the pressure
• la pressatura = the pressing / compaction / pressing process

In Italian, articles have to agree with the noun in gender and number, so both take la.

What does di mean in pressione di estrazione?

Here di links two nouns and works a lot like English noun-noun combinations.

• pressione di estrazione literally = pressure of extraction
• In more natural English, this often becomes extraction pressure

This is very common in Italian:

• camera di combustione = combustion chamber
• tempo di cottura = cooking time
• olio di oliva = olive oil

So di is not always translated word-for-word as of; often it just connects two nouns in a technical expression.

Why is it pressione di estrazione and not pressione dell'estrazione?

Both are possible in some contexts, but they are not exactly the same.

• pressione di estrazione sounds like a standard technical label: extraction pressure
• pressione dell'estrazione sounds more like the pressure of the extraction process, referring to a specific extraction

In technical or scientific language, Italian often prefers noun + di + noun without the article when naming a type or category.
