După puțin timp la microunde, ciorba este din nou caldă.

După usually means after. Here it introduces a time expression: După puțin timp... = After a short time...

Romanian often uses după + a noun phrase to set the time frame for what follows:

• După cină = after dinner
• După câteva minute = after a few minutes
• După puțin timp = after a short time

So it works very much like English after in this sentence.

Puțin timp means a short time or a little time.

• puțin = little / a little
• timp = time

Together, they form a natural expression meaning that only a small amount of time passed.

A learner should also notice that Romanian often uses puțin in ways that English might translate more naturally as a short rather than literally little:

• puțin timp = a short time
• puțină apă = a little water

La microunde is a very common Romanian way to mean in the microwave or in the microwave oven.

Even though English uses in, Romanian often uses la in this fixed expression:

• încălzesc mâncarea la microunde = I heat the food in the microwave

It is slightly idiomatic. A fuller version would be:

• în cuptorul cu microunde = in the microwave oven

So:

• la microunde = shorter, everyday, very common
• în cuptorul cu microunde = more explicit

Because microundă means microwave (wave), and microunde is the plural form.

In the expression cuptor cu microunde, the idea is literally oven with microwaves. From that full phrase, Romanian commonly shortens it to just:

• la microunde

So even though English says the microwave in the singular, Romanian uses this fixed plural form in the expression.

Ciorba is a type of soup, usually a sour soup in Romanian cuisine. It is a feminine noun.

The ending -a here marks the definite article, so:

• ciorbă = soup / a soup
• ciorba = the soup

Romanian usually attaches the definite article to the end of the noun instead of putting a separate word before it.

Other examples:

• fată = girl
• fata = the girl

So ciorba means the soup, not just soup.

Because caldă has to agree with ciorba, which is a feminine singular noun.

Romanian adjectives change form to match the noun:

• masculine singular: cald
• feminine singular: caldă

So:

• ceaiul este cald = the tea is warm
• ciorba este caldă = the soup is warm

This is standard adjective agreement.

Din nou means again.

In this sentence:

• este din nou caldă = is warm again

It is placed between the verb and the adjective, which is a very natural position in Romanian.

You could compare:

• Este din nou caldă = It is warm again.
• Este iar caldă = It’s warm again. (more informal, with iar)

So din nou is the more neutral and standard way to say again here.

Both are possible.

• este = full form, more neutral or slightly more formal
• e = shorter spoken form, very common in conversation

So these are both natural:

• Ciorba este din nou caldă.
• Ciorba e din nou caldă.

In writing, especially in learning materials, este often appears more often because it is the full form.

Because După puțin timp la microunde is an introductory time phrase. Romanian often separates this kind of opening phrase from the main clause with a comma.

So the structure is:

• După puțin timp la microunde, = introductory setting
• ciorba este din nou caldă. = main statement

The comma helps readability. In short sentences, punctuation can sometimes vary, but this comma is perfectly normal and helpful.

Yes, it is understandable and fairly natural, but it is a somewhat compressed everyday phrasing.

A few alternatives might sound a bit more explicit:

• După puțin timp în cuptorul cu microunde, ciorba este din nou caldă.
• După ce a stat puțin la microunde, ciorba este din nou caldă.
• După câteva minute la microunde, ciorba este din nou caldă.

The original sentence is fine, but Romanian often omits words when the meaning is obvious.

Yes. That would be very natural.

Compare:

• După puțin timp = after a short time
• După câteva minute = after a few minutes

The second one is more specific. If you actually mean microwave heating, câteva secunde or un minut may even be more realistic depending on the context.

Examples:

• După câteva secunde la microunde...
• După un minut la microunde...

So puțin timp is general, while câteva minute gives a more concrete duration.

Yes, depending on context.

Romanian cald / caldă often covers a range that English may split into warm and hot. For soup, caldă usually means it has been reheated and is pleasantly hot/warm again, not necessarily boiling.

If you want to emphasize very hot, Romanian might use:

• foarte caldă = very hot/warm
• fierbinte = hot, burning hot

So in this sentence, caldă is the normal everyday choice for reheated soup.

The sentence has this structure:

După puțin timp la microunde, ciorba este din nou caldă.

Breakdown:

• După puțin timp la microunde = time phrase / setting
• ciorba = subject
• este = verb
• din nou = adverbial expression
• caldă = predicate adjective

So the core clause is:

• ciorba este caldă = the soup is warm

And the sentence adds:

• după puțin timp la microunde = after a little time in the microwave
• din nou = again

This is a very common Romanian pattern: subject + a fi + adjective.
