Osate cambiare tutto.

Osate is the second-person plural form of osare, which means to dare.

In this sentence, it can be understood as:

• you all dare
• or, more naturally in context, dare! when speaking to more than one person

So osate cambiare tutto is addressing a group.

It can be both in form.

• Present indicative: voi osate = you (plural) dare
• Imperative for voi: osate! = dare!

In a short standalone sentence like Osate cambiare tutto., it is usually understood as an imperative: a command or encouragement.

The sentence is addressing more than one person.

That is because osate is the voi form:

• tu = singular you
• voi = plural you all / you guys

So this is like saying:

• You all, dare to change everything
• or simply Dare to change everything

After osare, Italian commonly uses an infinitive verb to say what someone dares to do.

So:

• osare + infinitive

Examples:

• Osate parlare. = Dare to speak.
• Oso chiedere. = I dare to ask.
• Osano protestare. = They dare to protest.

Here:

• osate = dare
• cambiare = to change

So together:

• osate cambiare = dare to change

Because in Italian, after osare, you normally use the infinitive directly, without a separate word equivalent to English to.

English says:

• dare to change

Italian says:

• osare cambiare

This is normal with many Italian verbs followed by another verb.

Tutto here means everything.

It is singular because it is being used as a pronoun meaning the whole of things / everything.

Compare:

• tutto = everything
• tutti = everyone / all (masculine plural people or things)

So:

• cambiare tutto = to change everything

If you said cambiare tutti, that would usually mean to change everyone, which is a different idea and often would not fit.

Italian often omits subject pronouns because the verb ending already shows the person.

So:

• (Voi) osate cambiare tutto.

The voi is understood from osate.

Leaving out the pronoun is completely normal and usually more natural.

Yes, grammatically it could.

Without extra context, osate cambiare tutto could be read as:

• You (plural) dare to change everything — statement
• Dare to change everything! — command/encouragement

In real life, punctuation, tone, and context decide the meaning. If it appears as a slogan, headline, or motivational phrase, the imperative reading is more likely.

For one person informally, you would use osa:

• Osa cambiare tutto. = Dare to change everything.

Other possibilities:

• Osi cambiare tutto. = formal singular you (Lei)
• Osiamo cambiare tutto. = Let’s dare to change everything

So the form of osare changes depending on who is being addressed.

Osare is a normal Italian verb, but it can sound a bit strong, elevated, or rhetorical depending on context.

In everyday speech, Italians may also use expressions like:

• avere il coraggio di = to have the courage to
• provare a = to try to (not the same meaning, but sometimes used in softer contexts)

So Osate cambiare tutto. sounds quite natural as:

• a slogan
• a motivational line
• an advertisement
• a dramatic or emphatic statement

A simple pronunciation guide:

• Osate ≈ oh-ZAH-teh
• cambiare ≈ kam-BYAH-reh
• tutto ≈ TOOT-toh

A rough full pronunciation:

• oh-ZAH-teh kam-BYAH-reh TOOT-toh

A couple of helpful notes:

• c before a sounds like k, so cambiare starts with kam-
• tt in tutto is pronounced more strongly than a single t

Yes — that is probably the most natural English translation if the sentence is being used as an exhortation or slogan.

Possible translations:

• Dare to change everything.
• Have the courage to change everything.
• You all dare to change everything. (if read as a statement)

So Dare to change everything is an excellent natural translation in many contexts.
