El arrendatario da por subsanado el desconchón.

Not in this sentence. Here, dar is part of the fixed structure dar por + adjective/past participle, which means to consider/regard something as being in a certain state.

So da por subsanado means something like:

• considers it remedied
• regards it as fixed
• deems it corrected

Useful comparisons:

• dar por terminado = to consider finished
• dar por perdido = to consider lost
• dar por hecho = to take for granted / consider certain

The subject is el arrendatario.

Because da is the third-person singular present form of dar, the sentence is talking about the tenant/lessee doing the judging or acknowledging.

So the basic structure is:

• El arrendatario = the subject
• da por subsanado = considers remedied
• el desconchón = the thing being considered remedied

No. It does not necessarily mean that.

It means the tenant considers or accepts that the damage has been remedied. The actual repair could have been done by:

• the landlord
• a contractor
• the tenant
• someone else

So this sentence is about assessment or acceptance, not about who carried out the repair.

Both can mean tenant, but the tone is different.

• arrendatario = more formal/legal
• inquilino = more everyday/common

In contracts, legal documents, property reports, and official correspondence in Spain, arrendatario is very normal. In casual conversation, people are more likely to say inquilino.

So in this sentence, arrendatario makes the tone sound formal and document-like.

Subsanado is the past participle of subsanar, a formal verb meaning:

• to remedy
• to correct
• to make good
• to put right

It is especially common in:

• legal language
• administrative language
• technical reports
• complaint handling
• property or maintenance documentation

In everyday speech, people might more often use:

• arreglado = fixed
• reparado = repaired
• solucionado = solved/sorted out

So subsanado sounds more official than ordinary conversation.

In Spain, desconchón usually refers to a chipped, flaked, or peeled patch on a surface.

Typical examples include damage to:

• paint
• plaster
• a wall
• enamel
• varnish
• other surface finishes

So it often describes a small area where the surface layer has come off.

This is the kind of word you often see in:

• property inventories
• inspection reports
• maintenance descriptions
• tenancy documents

Because it agrees with el desconchón, which is masculine singular.

In this kind of structure, the participle often agrees with the noun being described:

• el desconchón → subsanado
• la incidencia → subsanada
• los desperfectos → subsanados
• las humedades → subsanadas

So the form changes according to the gender and number of the thing considered fixed.

Here por is part of the fixed expression dar por + adjective/past participle.

It is best to learn the whole structure together, rather than trying to translate por by itself.

The pattern means:

• to regard something as
• to consider something
• to declare something to be in a certain state

More examples:

• dar por cerrado = to consider closed
• dar por resuelto = to consider settled/resolved
• dar por válido = to accept as valid
• dar por concluido = to consider concluded

Yes, very much so.

It sounds natural in:

• legal Spanish
• tenancy documents
• inspection reports
• administrative writing
• formal emails about repairs

A more everyday version might be:

• El inquilino considera arreglado el desperfecto.
• El inquilino da el desconchón por arreglado.
• El inquilino entiende que ya está arreglado.

So the original sentence is correct and natural, but it has a distinctly formal, professional tone.

Yes. Spanish allows some flexibility here.

You can say:

• El arrendatario da por subsanado el desconchón.
• El arrendatario da el desconchón por subsanado.

Both are possible.

The first version sounds very natural in formal writing. The second also works and may feel slightly more transparent to a learner, because el desconchón appears directly before por subsanado.

Yes, depending on the context.

Possible alternatives include:

• arreglar = to fix
• reparar = to repair
• solucionar = to solve/sort out
• corregir = to correct

But each has a slightly different feel:

• arreglar is broad and everyday
• reparar focuses on actual repair work
• solucionar focuses on solving a problem
• corregir focuses on correcting a fault or error
• subsanar sounds formal and official

So subsanar is especially suitable when the sentence appears in a property, legal, or administrative context.

It is fairly common in Spain when talking about property damage or surfaces, but it is still somewhat context-specific.

A learner might also see related words like:

• desperfecto = damage/defect
• desconchado = chipped/flaking
• humedad = damp
• grieta = crack
• mancha = stain

So desconchón is not a basic beginner word, but it is a useful one for housing, maintenance, and inventories.
