Durante l’interrogazione, sbaglio meno se parlo con calma.

Yes. Durante is a preposition meaning during.

So:

• Durante l’interrogazione = During the oral exam / during questioning

A useful point: unlike English during, durante is followed directly by a noun phrase, not by a full clause.

• durante la lezione = during the lesson
• durante l’estate = during the summer

If you want to say while + a verb, Italian usually uses something else, such as mentre.

• Mentre parlo, sbaglio meno. = While I speak, I make fewer mistakes.

Not in the police-drama sense. In school Italian, interrogazione often means an oral test, oral exam, or a situation where the teacher asks the student questions out loud.

So in this sentence:

• l’interrogazione = the oral exam / being questioned by the teacher

This is a very common school-related meaning in Italian, and it is a classic false friend for English speakers.

Because la becomes l’ before a singular feminine noun beginning with a vowel.

• la interrogazione → l’interrogazione

This is just normal elision in Italian.

Other examples:

• l’amica = the female friend
• l’estate = the summer
• l’ora = the hour

Sbaglio is the first person singular present tense of sbagliare, which means:

• to make a mistake
• to be wrong

So here:

• sbaglio meno = I make fewer mistakes / I’m wrong less often

Depending on context, both are possible translations.

Both are possible, but they are slightly different in style.

• sbaglio meno = I make fewer mistakes / I’m wrong less
• faccio meno errori = I make fewer errors

Sbagliare is very natural and common in everyday Italian. It often sounds simpler and more idiomatic than building the idea with fare + errori.

Compare:

• Se sono stanco, sbaglio di più.
• Se sono stanco, faccio più errori.

Both are correct, but sbaglio di più often feels a bit more natural in speech.

Because Italian usually does not need subject pronouns when the verb ending already shows who the subject is.

• sbaglio = I make mistakes / I’m wrong
• parlo = I speak

The ending -o tells you the subject is io.

You could say:

• Io sbaglio meno se parlo con calma.

But that would usually add emphasis, contrast, or clarity. In neutral sentences, Italian normally omits io.

Meno means less or fewer, depending on English wording.

In this sentence:

• sbaglio meno = I make fewer mistakes / I’m wrong less

Italian uses meno very broadly, where English may choose either less or fewer.

Other examples:

• Parlo meno. = I speak less.
• Faccio meno esercizi. = I do fewer exercises.
• Ho meno tempo. = I have less time.

Because this sentence expresses a real or likely condition, not a hypothetical or unlikely one.

• se parlo con calma = if I speak calmly / if I speak slowly and calmly

This is a normal, real condition, so Italian uses the present indicative:

• Se studio, capisco meglio.
• Se mangio troppo, sto male.

If the idea were more hypothetical, Italian could use the imperfect subjunctive plus conditional:

• Se parlassi con più calma, sbaglierei meno.
• If I spoke more calmly, I would make fewer mistakes.

So:

• se parlo = real/general condition
• se parlassi = more hypothetical

Because Italian often uses the present tense for general truths, habits, or repeated situations.

This sentence means something like:

• During the oral exam, I make fewer mistakes if I speak calmly.

It is not necessarily about one single moment only; it can describe a general pattern.

Italian commonly uses the present for this kind of statement:

• Se dormo bene, lavoro meglio.
• Se mangio piano, digerisco meglio.

Yes, literally it is with calm, but in natural English it usually means:

• calmly
• slowly
• without rushing
• in a relaxed way

So:

• parlo con calma = I speak calmly / I speak without rushing

Italian often uses con + noun where English might prefer an adverb.

Examples:

• Parla con attenzione. = He/She speaks carefully.
• Leggi con pazienza. = Read patiently.
• Rispondi con sincerità. = Answer sincerely.

Yes, calmamente is grammatically correct:

• Durante l’interrogazione, sbaglio meno se parlo calmamente.

However, con calma is usually more natural and common in everyday Italian.

In many cases, Italians prefer:

• parlare con calma rather than
• parlare calmamente

So calmamente is not wrong, but con calma sounds more idiomatic here.

Yes, the order can be changed.

Original:

• Sbaglio meno se parlo con calma.

Also possible:

• Se parlo con calma, sbaglio meno.

Both are correct. The difference is mostly one of emphasis and flow:

• Sbaglio meno se parlo con calma puts the main point first: I make fewer mistakes
• Se parlo con calma, sbaglio meno puts the condition first: If I speak calmly

Italian word order is flexible, especially with conditional clauses like se...

Yes, there is a slight difference.

• parlo con calma = I speak calmly, without anxiety or rushing
• parlo lentamente = I speak slowly

They can overlap, but they are not exactly the same.

Con calma focuses more on calmness, composure, not being rushed.
Lentamente focuses specifically on speed.

In the context of an oral exam, con calma suggests that staying relaxed helps reduce mistakes.

Yes.

• l’interrogazione = the oral exam / the questioning
• un’interrogazione = an oral exam / a questioning session

For example:

• Oggi ho un’interrogazione di storia. = Today I have an oral history test.

Notice that with the feminine singular indefinite article before a vowel, Italian uses un’:

• un’interrogazione not
• una interrogazione

Yes, it sounds natural.

It is clear and idiomatic, especially in a school context. A native speaker might also say similar versions such as:

• Durante l’interrogazione sbaglio meno se parlo con calma.
• Se parlo con calma durante l’interrogazione, sbaglio meno.

The comma after interrogazione is optional here. It helps separate the introductory phrase, but many people would also write the sentence without it.
