Non vogliamo fallire stavolta.

Non is the standard way to make a sentence negative in Italian. It usually goes before the conjugated verb.

So:

• vogliamo = we want
• non vogliamo = we do not want

In this sentence, non negates vogliamo, giving the idea we don’t want to...

Vogliamo is the 1st person plural form of volere (to want) in the present tense.

So:

• voglio = I want
• vuoi = you want
• vuole = he/she wants
• vogliamo = we want
• volete = you all want
• vogliono = they want

Here, vogliamo means we want.

Italian often drops subject pronouns when they are not needed, because the verb ending already shows who the subject is.

Since vogliamo clearly means we want, noi is optional.

So both are possible:

• Non vogliamo fallire stavolta.
• Noi non vogliamo fallire stavolta.

Adding noi gives extra emphasis, like we don’t want to fail this time.

After verbs like volere (to want), Italian normally uses an infinitive for the second verb.

Structure:

• volere + infinitive

So:

• vogliamo fallire = we want to fail

With negation:

• non vogliamo fallire = we do not want to fail

This works like English want to + verb.

Fallire means to fail.

It can be used in different ways depending on context:

• fallire = to fail
• fallire un obiettivo = to fail to reach a goal
• un’azienda fallisce = a company goes bankrupt / fails

In your sentence, it simply means to fail in a general sense.

Stavolta means this time.

It is a common, natural Italian word, especially in everyday speech. It is essentially a shortened form of questa volta.

So these are very similar:

• stavolta = this time
• questa volta = this time

Stavolta often sounds a bit more conversational.

Stavolta is commonly written as one word in modern Italian.

You may also see:

• sta volta

Both are understood, but stavolta is very common and standard in everyday use.

It comes from sta (a shortened form related to questa) + volta.

Yes. Italian allows some flexibility in word order, especially with time expressions like stavolta.

For example:

• Non vogliamo fallire stavolta.
• Stavolta non vogliamo fallire.

Both are correct.

The second version gives a little more emphasis to this time.

Yes, it sounds natural and idiomatic.

It has a very normal structure:

• non = not
• vogliamo = we want
• fallire = to fail
• stavolta = this time

A native speaker would easily say this, especially in a situation where people are determined to do better than before.

The tricky part is gli in vogliamo.

In standard Italian, gli here makes a sound similar to the lli in some pronunciations of million, though not exactly the same in all accents.

A rough guide:

• vo-glia-mo

But the glia part is pronounced as a single smooth sound, not like English g-lee-a.

Also:

• fallire = fahl-LEE-reh
• stavolta = סטah-VOL-tah / stah-VOL-tah

If you are learning pronunciation, vogliamo is worth practicing slowly.

Yes, absolutely.

These are both correct:

• Non vogliamo fallire stavolta.
• Non vogliamo fallire questa volta.

The meaning is basically the same.
Stavolta is often a bit more compact and conversational, while questa volta can sound slightly more neutral or explicit.
