A colazione mangio un po’ di mango.

A colazione means at breakfast or for breakfast. Italian often puts a time expression first to set the scene before the main action.

So:

• A colazione = at breakfast / for breakfast
• mangio un po’ di mango = I eat a bit of mango

A more neutral word order would also be:

• Mangio un po’ di mango a colazione.

Both are correct.

With meals, Italian often uses a + meal name without an article when speaking generally or habitually.

So you say:

• a colazione = at breakfast
• a pranzo = at lunch
• a cena = at dinner

Using alla colazione would usually sound like you are referring to a specific breakfast event, not breakfast in general.

Yes. Per colazione is also very common and often translates nicely as for breakfast.

Compare:

• A colazione mangio un po’ di mango.
• Per colazione mangio un po’ di mango.

Both are natural. Very roughly:

• a colazione = at breakfast / at breakfast time
• per colazione = for breakfast

In everyday use, the difference is small.

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

• mangio = I eat
• mangi = you eat
• mangia = he/she eats

So mangio already tells you the subject is I, and io is unnecessary unless you want emphasis or contrast.

For example:

• A colazione mangio un po’ di mango. = neutral
• Io mangio un po’ di mango, lui no. = I eat a bit of mango, he doesn’t

Un po’ di means a little, a bit of, or some.

It is a very common quantity expression:

• un po’ di pane = a bit of bread
• un po’ di latte = a little milk
• un po’ di mango = a bit of mango

It is often used when talking about an unspecified small amount.

After expressions of quantity like un po’, Italian normally uses di:

• un po’ di pane
• un po’ di acqua
• un po’ di mango

This is the normal pattern.

Del mango would suggest something more specific, like some of the mango already known in context.

Compare:

• Mangio un po’ di mango. = I eat a bit of mango.
• Mangio un po’ del mango che hai comprato. = I eat some of the mango that you bought.

Because po’ is a shortened form of poco.

So:

• poco → po’

The apostrophe shows that part of the word has been dropped. It is not written with an accent in standard Italian.

Correct:

• un po’

Not standard:

• un pò

Yes. Mango is a noun, and it is normally masculine:

• il mango = the mango

In your sentence, though, you do not see il because after un po’ di the noun appears without an article:

• un po’ di mango

As a loanword, mango is often treated as invariable in the plural by many speakers:

• i mango

But in this sentence, you only need the singular mass-style use: mango.

Yes, absolutely.

Both of these are correct:

• A colazione mangio un po’ di mango.
• Mangio un po’ di mango a colazione.

The difference is mostly about emphasis and flow:

• A colazione... puts the breakfast context first
• Mangio... starts with the action

Italian word order is more flexible than English word order.

Here it is being used more like a food substance, not as one whole fruit.

So un po’ di mango means:

• a bit of mango
• some mango

If you wanted to talk about one whole fruit, you would say:

• un mango = a mango

So compare:

• Mangio un po’ di mango. = I eat a bit of mango.
• Mangio un mango. = I eat a mango.

You put non before the verb:

• A colazione non mangio un po’ di mango.

But in natural Italian, if you mean I don’t eat mango for breakfast, it is often better to say:

• A colazione non mangio mango.
• A colazione non mangio mai mango. = I never eat mango for breakfast.

The exact wording depends on whether you want to negate the action in general or specifically the small quantity idea.

A simple pronunciation guide is:

ah ko-la-TSYO-ne MAN-jo oon po di MAN-go

A few useful points:

• colazione has the stress on -zio-
• mangio sounds roughly like MAN-jo
• po’ is short and stressed
• gi in mangio sounds like the j in jam

A more Italian-like rhythm would be:

A colaziÓne màn-gio un po’ di màn-go.
