Bărbatul este stabil după arsură.

Because bărbatul means the man, while bărbat means a man or just man in a general sense.

Romanian usually puts the definite article at the end of the noun instead of using a separate word like English the:

• bărbat = man / a man
• bărbatul = the man

So the ending -ul is the masculine singular definite article here.

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

So:

• eu sunt = I am
• tu ești = you are
• el/ea este = he/she is

In everyday Romanian, people also often say e instead of este:

• Bărbatul e stabil după arsură.

That is more informal, but it means the same thing.

Because bărbatul is a masculine singular noun, and the adjective has to match it.

So:

• bărbatul este stabil = the man is stable
• femeia este stabilă = the woman is stable

This is adjective agreement:

• masculine singular: stabil
• feminine singular: stabilă
• masculine plural: stabili
• feminine plural: stabile

Here după means after.

So după arsură means after the burn or after suffering a burn, depending on the context.

După is a very common Romanian preposition and can have several meanings, including:

• after in time: după masă = after lunch
• according to: după mine = according to me / in my opinion
• behind in some contexts

In this sentence, it clearly has the time/sequence meaning: after.

Romanian often leaves the noun indefinite after a preposition when the context already makes the situation clear.

So după arsură is a natural way to say after a burn / after the burn, especially in medical-style language.

Compare:

• după arsură = after burn / after a burn
• după arsura aceea = after that burn
• după arsura gravă = after the serious burn

A native English speaker may expect a definite form, but Romanian does not always use it where English does.

Yes, arsură is a feminine noun.

One clue is the ending -ă, which very often marks feminine singular nouns in Romanian. Also, its plural is:

• arsură = burn
• arsuri = burns

That feminine pattern is very common in Romanian.

It is in the accusative, because după normally takes the accusative.

However, for many Romanian nouns, the nominative and accusative forms look the same, so you do not see a special ending change here:

• nominative: arsură
• accusative: arsură

So grammatically it is accusative, but the form itself stays the same.

A rough pronunciation guide:

• bărbatul ≈ buhr-BAH-tool
• arsură ≈ ar-SOO-ruh

A few useful pronunciation notes:

• ă is a short, relaxed vowel, something like the a in sofa
• u in sur sounds like oo
• the stress is usually:
  • bărBAtul
  • arSUră

So the full sentence is roughly:

bărBAtul ESTE staBIL duPĂ arSUră

The letter ă is a very common Romanian vowel. It does not exist as a standard letter in English.

In this sentence, you see it in:

• bărbatul
• după
• arsură

It is pronounced like a quick, unstressed uh sound. Not exactly English a, e, or u.

For many learners, getting ă right takes practice, but even an approximate uh sound is a good start.

Yes, Romanian word order is somewhat flexible.

The neutral order here is:

• Bărbatul este stabil după arsură.

But you could also say:

• După arsură, bărbatul este stabil.

This shifts the focus a bit toward after the burn.

Romanian often allows this kind of movement more easily than English, although the basic subject + verb + complement order is still the most neutral.

Yes. Stabil is very natural in medical contexts.

It often means that a patient is in a stable condition, not getting worse at the moment. So in a hospital or emergency context, este stabil is a very normal phrase.

For example:

• Pacientul este stabil. = The patient is stable.
• Starea lui este stabilă. = His condition is stable.

So this sentence sounds like something you might hear in a medical update.

Yes, you could.

• după arsură sounds a bit more compact and medical
• după o arsură makes the noun more explicitly indefinite, meaning after a burn

Both are possible, but they may feel slightly different in tone:

• după arsură = more concise, sometimes more clinical
• după o arsură = a little more explicit and natural in ordinary explanation

Because the subject is already expressed by bărbatul = the man.

Romanian does not need an extra subject pronoun when the subject is already clearly stated.

So:

• Bărbatul este stabil. = The man is stable.
• El este stabil. = He is stable.

Both are correct, but you normally use el only when you want to emphasize he, contrast him with someone else, or when the subject has not already been named.
