Il committente chiama il libero professionista.

Because both committente and libero professionista are singular masculine nouns, and in this sentence they are both introduced with the definite article il.

• il committente = the client / the commissioning party
• il libero professionista = the freelance professional / self-employed professional

Italian uses articles more often than English does, so keeping il in both places is completely normal.

In this sentence, il committente is the subject and il libero professionista is the direct object.

So:

• Il committente = the person who calls
• chiama = calls
• il libero professionista = the person being called

Italian often relies on word order here, just like English. The first noun phrase is normally understood as the subject, and the second as the object.

Chiamare is the infinitive form, meaning to call.

In this sentence, the verb is conjugated for he/she/it in the present tense:

• io chiamo = I call
• tu chiami = you call
• lui/lei chiama = he/she calls

Since il committente is a singular third-person subject, Italian uses chiama.

Not necessarily. Chiamare can mean several related things, depending on context:

• to call someone on the phone
• to call out to someone
• to name / call someone or something

In a sentence like this, many learners will naturally understand it as calls in the sense of contacting someone, often by phone, but context decides the exact nuance.

Committente is not the most basic everyday word for client, but it is a real and useful term, especially in professional, legal, business, or contract-related contexts.

It often means:

• the person or company that commissions work
• the client who hires someone for a project
• the contracting party on the client side

So it can be more specific than simple cliente, depending on context.

Yes, libero literally means free, but in this expression it does not mean free of charge.

Libero professionista is a set phrase meaning a self-employed professional, an independent professional, or often a freelancer.

So here libero has the idea of being independent, not employed by a company in the usual salaried way.

It can be either masculine or feminine, depending on who it refers to.

• il professionista = the male professional
• la professionista = the female professional

So if the person were female, you could say:

• Il committente chiama la libera professionista

Notice that libera also changes to feminine to agree with professionista.

Because libero professionista is the normal fixed expression.

Italian adjective placement can vary, but some combinations become standard phrases. In this case, libero professionista is the established way to say self-employed professional / freelance professional.

If you move the adjective, it may sound unnatural or may change the nuance.

Yes, Italian word order is somewhat flexible, but the basic order here is the most neutral and natural:

• Il committente chiama il libero professionista.

You may also find other orders in special contexts for emphasis, but changing the order can make the sentence sound marked or ambiguous if there are no other clues.

For a learner, it is best to treat this as the standard pattern:

• subject + verb + object

Normally, no. That sounds incomplete or unnatural in standard Italian.

Italian usually needs articles with common nouns in sentences like this. So:

• Il committente chiama il libero professionista. = natural
• Committente chiama libero professionista. = generally not natural as a normal sentence

You might see article omission in notes, headlines, labels, or bureaucratic shorthand, but not in ordinary full sentences.

A simple pronunciation guide is:

eel kom-mee-TTEN-teh kee-AH-ma eel LEE-beh-ro pro-fes-syo-NEE-sta

A few useful points:

• chi is pronounced like kee, not like English chai
• tt in committente is pronounced more strongly than a single t
• stress falls on:
  • committènte
  • chiàma
  • professiónista

No. Like many Italian nouns ending in -e, committente can refer to a man or a woman. The article tells you the gender in the sentence:

• il committente = male client / commissioning party
• la committente = female client / commissioning party

So the noun form stays the same, but the article changes.

Both can sometimes be translated as client, but they are not always identical.

• cliente is the more general everyday word for customer/client
• committente often emphasizes the person or company that commissions work, especially in a professional or contractual relationship

So if someone hires an architect, designer, consultant, or other independent professional for a project, committente can be especially appropriate.
