Alla fine di ogni capoverso lascio una riga vuota, così il testo è più chiaro.

Because alla is the contraction of a + la.

• a = at / to
• la fine = the end

So:

• a la fine → alla fine

This kind of contraction is very common in Italian:

• a + il = al
• a + lo = allo
• a + i = ai
• a + gli = agli
• a + le = alle

Here, alla fine di ogni capoverso means at the end of each paragraph.

Italian uses fine di to mean the end of something.

So:

• la fine del libro = the end of the book
• la fine della giornata = the end of the day
• la fine di ogni capoverso = the end of each paragraph

This is very natural in Italian. English often says at the end of each paragraph, and Italian expresses that structure with alla fine di ....

Ogni means each / every, and in Italian it is followed by a singular noun with no article.

So:

• ogni capoverso = each paragraph
• ogni giorno = every day
• ogni studente = every student

Not:

• ogni il capoverso ❌
• ogni capoversi ❌

Even though the meaning is distributive and refers to many items, the noun after ogni stays singular.

In this sentence, capoverso means paragraph.

However, learners should know that capoverso and paragrafo are not always perfectly identical in all contexts.

• capoverso often refers specifically to a new paragraph in the layout of a text
• paragrafo can also mean a paragraph or a section, especially in more formal, grammatical, or structural contexts

In everyday writing, capoverso works very well for the idea of a paragraph separated visually in a text.

Yes, lascio literally means I leave, from the verb lasciare. But in Italian, lasciare is also used in the sense of leaving something in place or leaving some space.

So lascio una riga vuota means:

• I leave a blank line
• in more natural English, I leave one empty line

This is a normal way to express the idea in Italian.

Other examples:

• Lascio la porta aperta. = I leave the door open.
• Lascia uno spazio. = Leave a space.

Because Italian often omits subject pronouns when the verb ending already shows who the subject is.

• lascio = I leave
• the ending -o tells you the subject is io

So io is not necessary unless you want emphasis or contrast.

Compare:

• Lascio una riga vuota. = I leave a blank line.
• Io lascio una riga vuota, tu no. = I leave a blank line, you don’t.

Italian does this much more than English.

In Italian, adjectives often come after the noun, especially when they describe a basic, literal quality.

So:

• una riga vuota = an empty line
• un libro interessante = an interesting book
• una stanza grande = a big room

That said, some adjectives can come before the noun too, sometimes with a different nuance. But here riga vuota is the normal, straightforward order.

Also notice agreement:

• riga is feminine singular
• so the adjective is vuota (feminine singular), not vuoto

Yes, una riga in bianco is also possible and very natural in many contexts.

Both can mean a blank line:

• una riga vuota
• una riga in bianco

The sentence you have is perfectly correct with vuota. If anything, in bianco can sound a little more specifically like blank in the writing/printing sense, while vuota simply means empty. In practice, both are understandable and natural.

Here così means so, in this way, or therefore, depending on how literally you want to understand it.

The logic is:

• I leave a blank line at the end of each paragraph
• così = by doing that / so
• the text is clearer

So così links the action to its result.

It can have other meanings in other contexts too, such as:

• like this
• so
• thus

But in this sentence, it introduces the consequence.

Because così il testo è più chiaro is the result or consequence of the first part of the sentence.

The comma helps separate:

1. the action: Alla fine di ogni capoverso lascio una riga vuota
2. the result: così il testo è più chiaro

This is very natural punctuation in Italian, just as in English you might write:

• I leave a blank line after each paragraph, so the text is clearer.

Because chiaro must agree with testo, and testo is masculine singular.

So:

• il testo → masculine singular
• chiaro → masculine singular adjective

Compare:

• il testo è chiaro = the text is clear
• la frase è chiara = the sentence is clear

The feminine form chiara would be used with a feminine noun like frase, pagina, or spiegazione.

Here più chiaro means clearer in a general sense, not necessarily clearer than something else explicitly stated.

Italian can use più + adjective in two main ways:

1. General increase in quality

   • Il testo è più chiaro. = The text is clearer.

2. Direct comparison

   • Il testo è più chiaro del precedente. = The text is clearer than the previous one.

In your sentence, the comparison is implicit: leaving a blank line makes the text clearer than it would otherwise be. Since the second term of comparison is understood, Italian does not need del ....

Because the speaker is describing a usual habit or a general practice.

• lascio = I leave
• è = is

In both English and Italian, the present tense is commonly used for habitual actions:

• Ogni mattina bevo caffè. = Every morning I drink coffee.
• Alla fine di ogni capoverso lascio una riga vuota. = At the end of each paragraph I leave a blank line.

It does not necessarily mean the action is happening right now at this exact moment. It can simply describe what the person normally does.

Yes, the word order is natural and idiomatic.

The sentence is structured like this:

• Alla fine di ogni capoverso = time/place-type phrase
• lascio = verb
• una riga vuota = object
• così il testo è più chiaro = result

You could rearrange parts for emphasis, but the original version is very natural.

For example:

• Lascio una riga vuota alla fine di ogni capoverso, così il testo è più chiaro.

This is also correct, but the original puts emphasis first on where/when the blank line is left: at the end of each paragraph.
