Defibrilatorul este gata.

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

So:

• defibrilator = defibrillator
• defibrilatorul = the defibrillator

This is one of the biggest differences from English. The ending -ul is the definite article here.

For comparison:

• un defibrilator = a defibrillator
• defibrilatorul = the defibrillator

The dictionary form is defibrilator.

That is the basic, indefinite singular form. You add the definite article to get defibrilatorul.

So the pattern is:

• defibrilator = base form
• defibrilatorul = definite singular

Este is the 3rd person singular present tense form of a fi, which means to be.

So it corresponds to is in English.

A few useful forms of a fi are:

• eu sunt = I am
• tu ești = you are
• el/ea este = he/she is
• noi suntem = we are
• voi sunteți = you are
• ei/ele sunt = they are

In everyday Romanian, este is often shortened to e:

• Defibrilatorul este gata.
• Defibrilatorul e gata.

Both are correct.

Yes. Very often, yes.

In normal speech, Romanians frequently use e instead of este. So:

• Defibrilatorul este gata. = more full/formal/neutral
• Defibrilatorul e gata. = very common in everyday speech

Both are natural.

Gata is commonly treated as an invariable predicate adjective/adverb-like form, so it usually stays gata regardless of gender or number.

That means you can hear:

• El este gata.
• Ea este gata.
• Ei sunt gata.
• Ele sunt gata.

So in this sentence, gata does not change to match defibrilatorul.

This is very useful to remember, because English speakers often expect adjective agreement everywhere in Romanian, but gata is one of the words that usually stays the same.

Defibrilator is a neuter noun.

In Romanian, neuter nouns behave:

• like masculine in the singular
• like feminine in the plural

So in the singular you get forms like:

• un defibrilator
• defibrilatorul

But in the plural you get feminine-type forms, such as:

• două defibrilatoare
• defibrilatoarele

This is why the singular form may look masculine at first.

This is the normal Romanian order for a sentence like this:

• subject
  • verb
    • predicate adjective/state

So:

• Defibrilatorul = subject
• este = verb
• gata = state/description

That order is the most neutral and standard.

Romanian word order can change for emphasis, but this basic version is what learners should use first. For example, Defibrilatorul e gata is the most natural everyday variant.

No.

Romanian often leaves out subject pronouns unless they are needed for emphasis or clarity. Since the subject defibrilatorul is already stated, adding el would be unnecessary.

So the normal sentence is simply:

• Defibrilatorul este gata.

Not:

• Defibrilatorul el este gata.

A rough English-friendly pronunciation is:

deh-fee-bree-lah-TOR-ool ESS-teh GAH-tah

A few helpful points:

• r is usually tapped or rolled lightly
• Romanian vowels are usually clear and pure, not reduced as much as in English
• the stress in defibrilatorul falls on to
• este is pronounced with two clear syllables: es-te
• gata is GA-ta

If you want a more IPA-style version, it is approximately:

/de.fi.bri.laˈto.rul ˈes.te ˈga.ta/

It can mean a few related things depending on context.

Common uses of gata include:

• ready
• finished
• done
• sometimes even enough / stop / that’s it in conversation

Examples:

• Sunt gata. = I’m ready. / I’m done.
• Gata! = Done! / Enough! / That’s it!

So in Defibrilatorul este gata, the exact nuance comes from context, but grammatically the structure is straightforward: noun + to be + gata.
