Copiii mâncaseră deja, așa că au acceptat doar un pahar cu apă.

Because copiii = copii (children) + the definite article -i (the).

So the steps are:

• copil = child
• copii = children
• copiii = the children

That gives you three written i’s:

• one from the stem,
• one from the plural ending,
• one from the definite article.

In pronunciation, you do not pronounce them as three fully separate long vowels in normal speech. It sounds roughly like ko-PII with a clear palatal ending.

Mâncaseră is the pluperfect (Romanian: mai mult ca perfectul).

It corresponds to English had eaten.

So:

• Copiii mâncaseră deja = The children had already eaten

This tense is used because that action happened before the next past action:

• first: they had eaten
• later: they accepted only a glass of water

It comes from the verb a mânca = to eat.

The pluperfect in Romanian is usually formed from the verb stem plus special endings. For ei/ele (they), the ending here is -seră:

• mânca-
  • -seră → mâncaseră

This is a literary/standard past tense form, not a compound tense like English had eaten.

A few related forms are:

• eu mâncasem = I had eaten
• tu mâncaseși = you had eaten
• el/ea mâncase = he/she had eaten
• noi mâncaserăm = we had eaten
• voi mâncaserăți = you all had eaten
• ei/ele mâncaseră = they had eaten

Because the two actions are in a past sequence, and Romanian marks that clearly:

• mâncaseră = they had eaten already
• au acceptat = they accepted / did accept

So the first action is earlier than the second.

This is exactly like English:

• They had already eaten, so they accepted only a glass of water.

If Romanian used au mâncat deja, it would mean they already ate / have already eaten, but it would not show the earlier-than-the-next-action relationship as clearly.

Așa că means so, therefore, or that’s why.

In this sentence:

• Copiii mâncaseră deja, așa că...
• The children had already eaten, so...

It introduces a consequence or result.

A few close equivalents are:

• deci = so / therefore
• prin urmare = therefore / consequently (more formal)

But așa că is very common and natural in everyday Romanian.

Deja means already.

Here:

• mâncaseră deja = had already eaten

Its position is quite natural after the verb, but Romanian word order is fairly flexible. You may also hear:

• Copiii deja mâncaseră
• Copiii mâncaseră deja

Both are possible, though the version in your sentence sounds very normal and neutral.

Doar means only / just.

Here:

• au acceptat doar un pahar cu apă
• they accepted only / just a glass of water

In many contexts, doar and numai are very similar:

• doar un pahar
• numai un pahar

Both mean only one glass.

A small nuance:

• doar can sometimes sound a little more conversational or emphatic,
• numai can feel a bit more neutral or precise.

But in this sentence, either would work naturally.

This is a very good question, because both forms exist, but they are not always exactly the same.

• un pahar de apă = a glass of water
• un pahar cu apă = literally a glass with water

In many real-life situations, both can refer to the same thing. But the nuance is slightly different:

• de apă focuses on the type/content: a water glass, a glass of water
• cu apă focuses on the fact that the glass contains water

In this sentence, doar un pahar cu apă can sound natural because it highlights that they accepted nothing substantial, just a glass containing water.

Still, un pahar de apă would also be very common Romanian.

Because Romanian often omits a subject when it is already clear from context and from the verb form.

So instead of saying:

• Copiii mâncaseră deja, așa că copiii au acceptat...

Romanian naturally says:

• Copiii mâncaseră deja, așa că au acceptat...

The verb au acceptat already tells you the subject is they, and the previous clause makes it clear that they = the children.

This is very common in Romanian.

Not always.

Grammatically, au acceptat does mean accepted, but in English that can sound slightly formal or unusual depending on context.

In this sentence, a more natural English translation might sometimes be:

• They only took a glass of water
• They agreed to have only a glass of water

Romanian a accepta often means to accept, but it can also mean to agree to take / receive something.

So the exact English choice depends on context and style.

Because așa că introduces a result clause, and in Romanian it is normally separated by a comma.

So:

• Copiii mâncaseră deja, așa că au acceptat doar un pahar cu apă.

This punctuation is standard and natural.

It works similarly to English when you write:

• The children had already eaten, so they accepted only a glass of water.

Two important Romanian sounds here are:

• ă as in mâncaseră, așa
• ș as in așa

Roughly:

• ă = a short, neutral vowel, similar to the a in English sofa, but not exactly the same
• ș = sh as in ship

So:

• așa sounds roughly like a-SHA
• mâncaseră ends with -ră, where ă is that short neutral vowel

These letters are essential in writing Romanian correctly, because changing them can change the word or make it look misspelled.

Yes, Romanian has fairly flexible word order, though some versions sound more natural than others.

The original sentence is very natural:

• Copiii mâncaseră deja, așa că au acceptat doar un pahar cu apă.

Possible variations include:

• Copiii deja mâncaseră, așa că au acceptat doar un pahar cu apă.
• Așa că au acceptat doar un pahar cu apă, copiii mâncaseră deja.
  This is grammatically possible but much less natural in normal speech.

Romanian often changes word order for emphasis, but the original version is the best neutral choice.

It is mostly neutral standard Romanian.

Nothing in it is slangy or highly formal. You could use it in:

• conversation,
• writing,
• a school text,
• a story.

The only thing learners sometimes notice is the pluperfect mâncaseră, which can feel a bit more literary than some everyday alternatives. But it is still perfectly correct and natural, especially in narration where you want to show one past event happened before another.
