Il condomino paga le spese condominiali.

Condomino usually means a person who owns or is one of the co-owners of a unit in a condominium building. In everyday use, it often refers to a condo owner or a resident in the building, depending on context.

So in this sentence, il condomino is the person responsible for paying the building-related fees.

Italian uses il before most masculine singular nouns that begin with a normal consonant sound.

You use lo before masculine singular nouns beginning with:

• s
  • consonant, as in lo studente
• z, as in lo zio
• gn, ps, x, and a few other special beginnings

Since condomino begins with a simple c sound, the correct article is il.

Paga is the third person singular of pagare in the present tense.

The subject is il condomino, which is singular, so the verb must also be singular:

• io pago = I pay
• tu paghi = you pay
• lui/lei paga = he/she pays

So Il condomino paga means The condo owner pays or A condo owner pays.

In Italian, spese is very commonly used in the plural to mean expenses, costs, or fees.

So:

• la spesa = the expense / the shopping, depending on context
• le spese = the expenses / the fees

In housing and building contexts, spese condominiali is the normal expression for condominium fees or building maintenance charges. Using the plural sounds natural because these are seen as a set of charges, not just one single expense.

Because condominiali is an adjective modifying spese, and Italian adjectives must agree with the noun they describe.

Here:

• spese is feminine plural
• so the adjective must also be feminine plural

The pattern is:

• condominiale = singular
• condominiali = plural

So:

• la spesa condominiale = the condominium expense
• le spese condominiali = the condominium expenses

They are related words:

• condominio = condominium / condo building
• condomino = condo owner / co-owner / resident in that condominium context
• condominiale = relating to the condominium
• condominiali = plural form of condominiale

So spese condominiali literally means condominium-related expenses.

Yes. Italian often uses the definite article il to express a general idea.

So Il condomino paga le spese condominiali can mean:

• The condo owner pays the condominium fees
• or more generally, A condo owner pays condominium fees

This is similar to how English sometimes says The lion is a dangerous animal to mean lions in general.

Yes, you could, and the meaning is very similar.

• le spese condominiali = condominium fees / condo expenses
• le spese del condominio = the expenses of the condominium

The version with the adjective, condominiali, is especially common and compact. It is the standard phrase you will often see in real estate, leases, and apartment-related discussions.

Because pagare takes a direct object.

In Italian, you simply pay something:

• pagare le spese
• pagare il conto
• pagare l’affitto

So le spese condominiali is the direct object of paga. No extra preposition is needed.

Yes, but Il condomino paga le spese condominiali is the most neutral and straightforward order.

Italian often uses:

• subject + verb + object

You might sometimes hear different orders for emphasis, such as:

• Le spese condominiali le paga il condomino

That version puts emphasis on who pays the fees. But for a learner, the original sentence is the clearest and most standard.

Here are the main forms:

• il condomino → i condomini
• la spesa condominiale → le spese condominiali

So the full plural sentence would be:

• I condomini pagano le spese condominiali.

Notice the changes:

• il → i
• condomino → condomini
• paga → pagano

Yes, it can be.

In Italian:

• fare la spesa = to do the shopping / buy groceries
• spesa can also mean expense or cost

But in spese condominiali, the context is completely different. Here it clearly means expenses, fees, or charges, not shopping. Context usually makes the meaning obvious.
