Lustra este nouă.

The basic noun is lustră, which means chandelier.

In this sentence, lustra means the chandelier. Romanian usually adds the definite article to the end of the noun, instead of putting a separate word like the in front.

So:

• lustră = a chandelier / chandelier
• lustra = the chandelier

This is why the word appears as lustra here.

You would say o lustră.

So:

• o lustră = a chandelier
• lustra = the chandelier

Romanian uses o as the feminine singular indefinite article here, like English a.

Este means is.

It is the 3rd person singular form of the verb a fi = to be.

So:

• Lustra = The chandelier
• este = is
• nouă = new

Together: Lustra este nouă = The chandelier is new.

Yes. In everyday Romanian, e is a very common short form of este.

So both are correct:

• Lustra este nouă.
• Lustra e nouă.

The second one sounds more natural in casual speech.

Because the adjective has to agree with the noun.

Lustră / lustra is a feminine singular noun, so the adjective new must also be in the feminine singular form.

Forms of nou:

• nou = masculine singular
• nouă = feminine singular
• noi = plural

Examples:

• un scaun nou = a new chair
• o lustră nouă = a new chandelier
• lustre noi = new chandeliers

Because here nouă is a predicate adjective: it describes the subject through the verb to be.

Compare:

• o lustră nouă = a new chandelier
  
  • here the adjective directly modifies the noun
• Lustra este nouă = The chandelier is new
  
  • here the adjective comes after is

This works very much like English.

Because Romanian does not need a subject pronoun here when the subject is already named.

English says:

• It is new
• The chandelier is new

Romanian can say:

• Este nouă = It is new / She is new / It’s new, depending on context
• Lustra este nouă = The chandelier is new

Romanian often leaves out subject pronouns when they are unnecessary.

The normal, neutral order is:

• Lustra este nouă.

That is the most straightforward way to say The chandelier is new.

You will also often hear:

• Lustra e nouă.

For a yes/no question, Romanian often keeps the same word order and uses intonation:

• Lustra e nouă? = Is the chandelier new?

A version like Este lustra nouă? is possible, but it sounds more marked or formal.

Yes, Romanian has several different words spelled nouă, and context tells you which one it is.

nouă can mean:

• new — feminine singular adjective
• nine — the number
• to us / for us — pronoun form

In Lustra este nouă, it clearly means new, because it describes lustra.

This is a very common question.

• nouă is the regular feminine singular form of the adjective new
• noua is typically used when the adjective comes before a definite feminine noun

Compare:

• o lustră nouă = a new chandelier
• lustra este nouă = the chandelier is new
• noua lustră = the new chandelier

So in your sentence, nouă is correct because it comes after este.

A simple English-friendly approximation is:

LOOS-tra YES-te NO-uh

A few helpful notes:

• u in lustra sounds like oo
• e in este is often pronounced like ye at the start: YES-te
• ă is a short neutral vowel, something like the a in sofa
• nouă has two syllables: NO-ŭh / NO-uh

So the whole sentence is roughly:

LOOS-tra YES-te NO-uh

You would say:

Lustrele sunt noi. = The chandeliers are new.

Breakdown:

• lustrele = the chandeliers
• sunt = are
• noi = new (plural)

So the pattern changes like this:

• Lustra este nouă. = The chandelier is new.
• Lustrele sunt noi. = The chandeliers are new.
