El arrendador confirma el desmontaje.

Arrendador means landlord or lessor: the person who rents out a property or item.

In Spain, arrendador is a fairly formal/legal word. In everyday conversation, people might also say:

• casero = landlord, more everyday
• propietario = owner, but not always specifically the landlord

So El arrendador confirma el desmontaje sounds a bit official or administrative.

Desmontaje is a noun meaning dismantling, disassembly, or sometimes removal/uninstallation, depending on context.

It comes from the verb desmontar, which means:

• to take apart
• to dismantle
• to remove something that has been installed

So el desmontaje refers to the dismantling/removal as an action or process.

Because both arrendador and desmontaje are singular masculine nouns.

• el arrendador = the landlord
• el desmontaje = the dismantling

Spanish usually uses the definite article more regularly than English, especially in formal statements like this one.

Confirma is the third-person singular present tense of confirmar.

So it can mean:

• he confirms
• she confirms
• it confirms
• the landlord confirms

In this sentence, the subject is el arrendador, so confirma means the landlord confirms.

Because el desmontaje is a direct object that refers to a thing/event, not a person.

In Spanish, the personal a is generally used before specific people (and sometimes animals), not before things.

So:

• El arrendador confirma el desmontaje = correct
• El arrendador confirma a el desmontaje = incorrect

Also, a el would normally contract to al, but in this sentence no a is needed at all.

It sounds formal, administrative, or legal.

That is mainly because of:

• arrendador instead of a more everyday word like casero
• desmontaje, which sounds technical or official depending on context
• the overall concise, document-like style

In ordinary conversation, a person might say something more natural like:

• El casero confirma que lo van a desmontar.
• El propietario confirma la retirada.

But your original sentence is perfectly correct, especially in written or official contexts.

This is the standard Spanish subject + verb + object order:

• El arrendador = subject
• confirma = verb
• el desmontaje = direct object

It matches the basic English pattern The landlord confirms the dismantling.

Spanish can sometimes change word order for emphasis, but this neutral order is the most straightforward and common.

Yes. The exact translation depends on context.

Possible English meanings include:

• dismantling
• disassembly
• removal
• uninstallation

For example:

• for furniture or equipment: dismantling
• for a device or fitted unit: removal or uninstallation
• in a technical report: disassembly

So if the meaning has already been given to the learner, that context is very important for choosing the best English equivalent.

It can be used more broadly for a lessor: someone who rents something out, not only property.

However, in many common situations, learners will most often see it in housing or rental-contract contexts.

Related words:

• arrendador = landlord / lessor
• arrendatario = tenant / lessee
• arrendamiento = lease / rental agreement

These are all quite formal terms.

A rough pronunciation guide is:

el ah-ren-dah-DOR con-FEER-ma el des-mon-TA-he

A few useful pronunciation points:

• rr in arrendador is a strong rolled sound
• j in desmontaje sounds like a strong English h, but rougher and further back in the mouth
• the stress falls on:
  • arrendador
  • confirma
  • desmontaje

In standard Spain Spanish, the sentence sounds something like:

el arren-da-DOR kon-FIR-ma el des-mon-TA-je

Not in exactly the same structure.

Your sentence uses a noun:

• el desmontaje = the dismantling

If you want to use the verb, you would normally need a different construction, for example:

• El arrendador confirma que se va a desmontar.
• El arrendador confirma desmontarlo.
  This is possible in some contexts, but it changes the structure and may sound less natural unless the object is already clear.

So confirma el desmontaje is a neat, noun-based, formal way to say it.
