Dospeće je sutra.

It is a noun, not a verb. In Dospeće je sutra, dospeće is the subject of the sentence.

Grammatically, it is:

• nominative
• singular
• neuter

This can be confusing because English often expresses the same idea with a phrase like the due date or with a verb like is due.

Je is the 3rd person singular present form of biti (to be).

So the structure is basically:

• dospeće = subject
• je = is
• sutra = tomorrow

Literally, the sentence is built like X is tomorrow.

In standard Serbian, you normally need je in a full sentence like this. Leaving it out would sound incomplete, except in very informal notes, headlines, or labels.

Because Serbian has no articles. There is no direct equivalent of English a/an/the.

So dospeće can mean:

• a due date
• the due date

Which one is meant depends on the context. In most real situations, the listener already knows which due date is being discussed.

Because sutra is an adverb of time meaning tomorrow.

Serbian often uses time adverbs directly, without any preposition:

• danas = today
• sutra = tomorrow
• juče = yesterday

So je sutra is perfectly normal.

Compare that with expressions that do use a preposition:

• u ponedeljak = on Monday
• u martu = in March

But with sutra, no preposition is needed.

Yes. It is singular.

For English speakers, an -e ending can look unusual, but in Serbian many neuter singular nouns end in -e or -o.

You can also tell it is singular because the verb is je (is), not su (are).

Yes, Serbian word order is fairly flexible.

The most neutral version here is:

• Dospeće je sutra.

But you can also say:

• Sutra je dospeće.

That version puts more focus on sutra.

One important detail: je is a clitic, so it usually goes in the second position of the sentence or clause. That is why in Sutra je dospeće, je comes right after sutra.

Yes, it is relatively formal and is especially common in:

• banking
• finance
• legal or administrative language
• bills, loans, and payment schedules

A less technical word is often rok (deadline), but that is not always exactly the same thing.

For example:

• Rok za plaćanje je sutra. = The payment deadline is tomorrow.
• Dospeće je sutra. = The obligation/payment/maturity falls due tomorrow.

So dospeće sounds more specialized.

Yes. It is related to the verb dospeti, which can mean things like to arrive, to reach, or in financial/legal contexts to become due.

So dospeće is a noun built from that idea: the point at which something comes due.

That helps explain why this noun is often used for:

• a due date
• maturity
• the moment an obligation becomes payable

The tricky part is ć.

• ć is a soft consonant
• it is softer than č
• English does not have a perfect equivalent

A rough approximation is something like dos-peh-cheh, but with a softer ch sound in the last syllable.

So the word is pronounced approximately as:

• do-spe-će

If you already know the difference:

• č is harder
• ć is softer

That distinction matters in Serbian, even though English speakers often need practice to hear and produce it clearly.
