Richiamo Marco domani.

In Italian, the present tense is very often used for the near future, especially when a time word like domani already makes the timing clear.

So Richiamo Marco domani is a very natural way to say that the action will happen tomorrow.

This is similar to English sentences like:

• I’m calling Marco tomorrow
• I see him tomorrow

The future idea comes from domani, not from the verb ending.

Yes. Richiamerò Marco domani is also correct.

The difference is mainly one of style and feel:

• Richiamo Marco domani = very natural, conversational, common in everyday speech
• Richiamerò Marco domani = explicitly future, sometimes a bit more formal or deliberate

Both are correct. Italian often prefers the present tense when the future time is already clear.

Italian often leaves out subject pronouns because the verb ending already shows who the subject is.

Here, richiamo ends in -o, which tells you the subject is I.

So:

• Richiamo Marco domani = I’ll call Marco back tomorrow
• Io richiamo Marco domani = also correct, but io is usually added only for emphasis, contrast, or clarity

For example:

• Io richiamo Marco, tu richiama Sara.
  = I’ll call Marco back, you call Sara back.

Because Marco is the direct object of the verb richiamare.

With richiamare, the person being called back is normally used without a preposition:

• Richiamo Marco
• Richiamiamo i clienti
• Ti richiamo più tardi

This can be confusing because some other Italian verbs for contacting people work differently. For example:

• telefonare a Marco
• scrivere a Marco

But with chiamare and richiamare, you normally use the person directly, with no a.

The infinitive is richiamare.

Richiamo is the 1st person singular present indicative form:

• io richiamo = I call back / I’m calling back / I’ll call back

Basic present-tense pattern:

• io richiamo
• tu richiami
• lui/lei richiama
• noi richiamiamo
• voi richiamate
• loro richiamano

So in the sentence, richiamo simply means I call back / I’m calling back / I’ll call back, depending on context.

Not exactly.

• chiamare = to call
• richiamare = to call back, call again, or recall, depending on context

In phone contexts, richiamare often means to call back.

So:

• Chiamo Marco = I call Marco
• Richiamo Marco = I call Marco back

The prefix ri- often adds the idea of again or back.

Yes. Italian word order is flexible.

All of these are possible:

• Richiamo Marco domani
• Domani richiamo Marco

Both are natural. The second one puts a little more focus on tomorrow.

Richiamo domani Marco is much less natural in normal speech. It is not the usual default order.

So the safest choices are:

• Richiamo Marco domani
• Domani richiamo Marco

Yes. If Marco is replaced by a direct object pronoun, you use lo.

So:

• Richiamo Marco domani becomes
• Lo richiamo domani

In Italian, object pronouns usually come before the conjugated verb:

• Lo richiamo
• La richiamo
• Li richiamo

So Lo richiamo domani means I’ll call him back tomorrow.

It is pronounced roughly ree-KYAH-mo.

A few useful pronunciation points:

• ri- sounds like ree
• chi here has a hard k sound, not a sh sound
• the stress is on -chia-

So it is:

• ri-CHIA-mo
• approximately ree-KYAH-mo

This is because in Italian, ch before i or e keeps the hard k sound.

Yes, very natural.

A native speaker would easily say:

• Richiamo Marco domani

It sounds normal, especially in conversation, when someone is talking about plans or promises. Using the present tense with domani is one of the most common and natural patterns in spoken Italian.
