Abbiamo parecchie domande.

Abbiamo is the first-person plural form of avere, which means to have.

So:

• io ho = I have
• tu hai = you have
• lui/lei ha = he/she has
• noi abbiamo = we have
• voi avete = you all have
• loro hanno = they have

In Abbiamo parecchie domande, abbiamo means we have.

In Italian, subject pronouns are often left out because the verb ending already tells you who the subject is.

Here, abbiamo clearly means we have, so noi is not necessary.

• Abbiamo parecchie domande = perfectly normal
• Noi abbiamo parecchie domande = also correct, but more emphatic, as in we have quite a few questions

Italian does this much more often than English.

Parecchie means something like:

• quite a few
• several
• a good number of
• sometimes simply many

It suggests a fairly noticeable number, but not necessarily a huge one. In this sentence, it gives the idea that we have quite a few questions.

Compared with similar words:

• molte = many
• tante = lots of / many
• parecchie = quite a few / several / a fair number of

Because parecchio is an adjective here, and Italian adjectives must agree with the noun they describe.

The noun is domande, which is:

• feminine
• plural

So the adjective must also be feminine plural:

• parecchio = masculine singular
• parecchia = feminine singular
• parecchi = masculine plural
• parecchie = feminine plural

Since domande is feminine plural, the correct form is parecchie.

The singular form is domanda, meaning question.

• domanda = feminine singular
• domande = feminine plural

Many Italian nouns ending in -a are feminine, and their plural usually ends in -e.

So:

• una domanda = one question
• due domande = two questions

That is why the adjective becomes parecchie to match it.

Because parecchie already works as a determiner-like adjective, similar to English many or several.

In English, you say:

• We have many questions
• not usually We have the many questions

Italian works similarly here:

• Abbiamo parecchie domande = We have quite a few questions

You normally do not put an article before parecchie in this kind of sentence.

Yes, both are correct.

They are close in meaning, but the tone is slightly different:

• Abbiamo molte domande = We have many questions
• Abbiamo tante domande = We have lots of questions
• Abbiamo parecchie domande = We have quite a few questions / several questions

All three are natural. Parecchie can sound a little like a fair number of.

The normal word order is:

Abbiamo parecchie domande

This is the most neutral and natural way to say it.

Italian word order can sometimes change for emphasis, but in a simple sentence like this, the standard order is best:

• verb: abbiamo
• quantity/adjective: parecchie
• noun: domande

A different order might sound marked, poetic, or strongly emphatic.

It is pronounced approximately ahb-BYAH-mo.

A few helpful points:

• the bb is a doubled consonant, so it is held a bit longer than a single b
• ia in -bbia- combines into a sound like byah
• stress falls on -bia-: ab-BIA-mo

So the rhythm is:

ab-BIA-mo

Usually, domande means questions, especially literal questions that someone asks.

Examples:

• Ho una domanda. = I have a question.
• Ci sono molte domande. = There are many questions.

Depending on context, domanda can also mean request or demand in some formal or economic uses, but in a sentence like Abbiamo parecchie domande, a learner should understand it first as questions.

Yes. Abbiamo parecchie domande is neutral and natural in both formal and informal contexts.

You could use it:

• in class
• in a meeting
• in an email
• in conversation

If needed, you could make it more formal by adding context around it, but the sentence itself is already perfectly acceptable in standard Italian.
