A Ana é a nova inquilina do condomínio.

In European Portuguese, it is very common to use the definite article before a person’s first name.

So A Ana means simply Ana, not the Ana in the English sense.

A few notes:

• a = feminine singular the
• o = masculine singular the

Examples:

• A Ana chegou. = Ana arrived.
• O Pedro saiu. = Pedro left.

This is especially normal in Portugal. In English, we do not do this with names, so it often feels strange at first.

Because é comes from ser, which is used for:

• identity
• classification
• profession
• roles
• more permanent or defining information

Here, Ana is being identified as the new tenant, so Portuguese uses ser:

• A Ana é a nova inquilina do condomínio.

Using estar here would sound wrong, because estar is usually for:

• location
• condition
• temporary states

Compare:

• A Ana é médica. = Ana is a doctor.
• A Ana está cansada. = Ana is tired.

Even if being the new tenant is temporary in real life, the sentence is still classifying her role, so ser is the natural choice.

Because Ana is female, and Portuguese grammar requires agreement in gender and number.

Here:

• a = feminine singular article
• nova = feminine singular adjective
• inquilina = feminine singular noun

All three match.

If the tenant were male, it would be:

• O João é o novo inquilino do condomínio.

So the pattern is:

• a nova inquilina = the new female tenant
• o novo inquilino = the new male tenant

This kind of agreement is one of the biggest differences from English.

Yes, inquilina is a normal everyday word in Portugal. It means female tenant.

Related forms:

• inquilino = male tenant
• inquilina = female tenant
• inquilinos = tenants (mixed group or masculine plural)
• inquilinas = female tenants

In more formal or legal Portuguese, you may also see:

• arrendatária = female tenant
• arrendatário = male tenant

But in ordinary speech, inquilina is very natural.

Do is a contraction:

• de + o = do

So:

• do condomínio literally means of the condominium

This kind of contraction is extremely common in Portuguese.

Other common ones:

• de + a = da
• de + os = dos
• de + as = das

Examples:

• a porta do prédio = the door of the building
• a garagem da casa = the garage of the house

In this sentence, do condomínio links the tenant to that residential building/complex.

Not always exactly.

In Portugal, condomínio often refers to:

• a residential building or housing complex under shared ownership
• the collective property arrangement
• sometimes the residents’ association or the shared/common areas

So in a sentence like this, do condomínio usually means something like:

• of the apartment building
• of the residential complex
• of the condo building/community

It does not necessarily match every nuance of American English condominium.

Yes, a inquilina nova is possible, but a nova inquilina is more natural here.

With novo/nova, position can affect style or nuance:

• a nova inquilina = the new tenant
  
  • very natural when identifying someone in a role
• a inquilina nova = the tenant who is new
  
  • can sound more contrastive or descriptive

In this sentence, the speaker is introducing Ana as the new tenant, so a nova inquilina is the usual choice.

This is a good example of how adjective position in Portuguese is more flexible than in English.

Because the sentence is not saying where Ana is physically located. It is saying what her relationship is to the place.

• inquilina do condomínio = tenant of the condominium/building/complex

If you used no condomínio (em + o = no), that would focus more on location:

• A Ana está no condomínio. = Ana is at/in the condominium.
• A Ana mora no condomínio. = Ana lives in the condominium.

So:

• do condomínio = belonging/association
• no condomínio = location

A simple learner-friendly approximation is:

uh AH-nuh eh uh NO-vuh een-kee-LEE-nuh doo kon-doo-MEE-nyoo

A few useful pronunciation points:

• Ana: stress on the first syllable
• nova: stress on no
• inquilina: stress on li
• condomínio: stress on mí

In European Portuguese, unstressed vowels are often reduced, so the first a in A Ana is usually a weak sound, not a full clear ah.

Also:

• é is an open eh sound
• nh in condomínio is like the ny sound in canyon

Not in this sentence, if you want to say who the person is.

Portuguese often drops subject pronouns like eu, tu, ele, ela, because the verb form already gives clues:

• Sou estudante. = I am a student.
• És novo aqui? = Are you new here?

But here Ana is the actual subject noun, and it gives the important information about who we are talking about:

• A Ana é a nova inquilina do condomínio.

You could replace it with Ela if the person is already clear from context:

• Ela é a nova inquilina do condomínio.

But you would not normally just say:

• É a nova inquilina do condomínio. unless the context already makes the identity obvious.
