Moartea este tristă.

Because Romanian usually puts the definite article at the end of the noun, not before it.

• moarte = death
• moartea = the death

In this sentence, moartea is the definite form. Romanian often uses the definite form with abstract ideas in places where English may just say death in a general sense.

Romanian commonly uses the definite form for general or abstract statements.

So Moartea este tristă can mean something like a general statement about death, not necessarily one specific event. This is more natural in Romanian than using the bare noun moarte here.

Este means is. It is the 3rd person singular present form of a fi = to be.

So the structure is:

• moartea = subject
• este = is
• tristă = adjective

Yes. That is very common.

• este = full form
• e = shorter everyday form

Both are correct:

• Moartea este tristă.
• Moartea e tristă.

The version with este may sound a little more careful or formal.

Because Romanian adjectives usually agree with the noun in gender and number.

moartea is feminine singular, so the adjective must also be feminine singular:

• masculine singular: trist
• feminine singular: tristă

So:

• băiatul este trist = the boy is sad
• moartea este tristă = death is sad

Yes. Moarte is feminine.

You can see that in this sentence because:

• the definite form is moartea
• the adjective is feminine: tristă

So the grammar clearly shows feminine agreement.

A rough guide is TREES-tuh, but with a very short final vowel.

The last letter ă is an important Romanian sound. It is like the a in English sofa or the second a in about: a short neutral vowel.

So:

• tristă ≈ TREES-tuh

The stress is on the first syllable: TRIS-tă.

A rough pronunciation is:

MOAR-tea ES-te TREES-tuh

A few notes:

• moar- sounds like moar in more plus a slight a glide
• este is pronounced clearly: ES-te
• tristă ends with the short ă sound

The stress is roughly:

• MOAR-tea
• ES-te
• TRIS-tă

No. This is the normal, neutral word order:

subject + verb + adjective

So:

• Moartea = subject
• este = verb
• tristă = predicate adjective

You could change the order for emphasis or style, but Moartea este tristă is the plain standard order.

Normally, no. In standard Romanian, you usually keep the verb a fi in this kind of sentence.

So Moartea tristă is not the normal way to say this as a complete sentence.

You need:

• Moartea este tristă or
• Moartea e tristă

It is an adjective.

It describes the subject moartea, so it must agree with it in gender and number. That is why it appears in the feminine singular form tristă.

It is not an adverb, because it is not describing the verb este.

It is in the nominative, because it is the subject of the sentence.

In Romanian, the nominative and accusative often look the same, so the form itself may not change much. Here, the important point is that moartea is the subject performing the role that death does in English.
