Сьомий платіж не пройшов.

• Сьомий = seventh
• платіж = payment
• не = not / didn’t
• пройшов = literally went through / passed, but here it means was not processed successfully or didn’t go through

So the sentence is literally something like The seventh payment did not go through.

Yes. Сьомий is an ordinal number, meaning seventh, and ordinal numbers in Ukrainian behave like adjectives.

That means сьомий changes its ending to match the noun it describes in:

• gender
• number
• case

Here it describes платіж, which is:

• masculine
• singular
• nominative

So the correct form is сьомий.

Платіж is in the nominative singular.

It is the grammatical subject of the sentence: the payment is the thing that did not go through.

So:

• сьомий платіж = the seventh payment as the subject
• that is why both words are in nominative singular masculine

Ukrainian does not have articles like a or the.

So платіж can mean:

• a payment
• the payment

The exact meaning comes from context. In this sentence, English would usually translate it as the seventh payment because ordinal numbers often sound definite in context.

In Ukrainian, не is usually written separately from verbs.

So:

• не пройшов = did not go through

This is normal and expected.

Compare:

• знаю = I know
• не знаю = I do not know

That is a very good question, because пройти / пройшов has several meanings.

Literally, it can mean:

• to pass
• to go through
• to walk past

But in many practical contexts, especially with:

• payments
• transactions
• applications
• checks
• documents

it means to go through successfully, to be processed, or to be approved/accepted.

So платіж не пройшов means:

• the payment didn’t go through
• the payment failed
• the payment was not processed

Because Ukrainian past tense agrees with gender and number.

The noun платіж is masculine singular, so the verb in the past tense is masculine singular too:

• masculine: пройшов
• feminine: пройшла
• neuter: пройшло
• plural: пройшли

Since платіж is masculine, the sentence uses пройшов.

Yes, пройшов is the past tense masculine singular form of пройти.

A simple way to think of it:

• dictionary form: пройти = to go through / to pass
• past masculine: пройшов = went through / passed
• with не: не пройшов = didn’t go through

In Ukrainian, past tense often shows gender in the singular, which is something English does not do.

Пройти is perfective.

That matters because perfective verbs usually describe:

• a completed event
• a single result
• whether something succeeded or happened

Here that makes perfect sense, because a payment either:

• went through successfully, or
• did not

So не пройшов focuses on the result: the payment failed to complete successfully.

The imperfective partner is проходити. For example:

• Платіж проходив довго. = The payment was taking a long time / was being processed for a long time.

But Платіж не пройшов is about the final outcome.

Yes. Ukrainian word order is flexible, although the neutral order here is very natural:

• Сьомий платіж не пройшов.

You might also hear:

• Не пройшов сьомий платіж.
• Платіж сьомий не пройшов. — less neutral, more marked

Changing the order usually changes emphasis, not the basic meaning.

The original sentence sounds like a straightforward statement of fact.

Usually платіж means payment.

Depending on context, it can also be understood as:

• a payment attempt
• a transaction
• a scheduled payment

So Сьомий платіж не пройшов could mean:

• the seventh payment in a series failed
• the seventh transaction did not process
• the seventh installment did not go through

The exact English wording depends on the situation.

A learner may notice two tricky things here:

• сь is soft
• ь does not make a sound by itself; it softens the consonant before it

So сьомий is approximately:

• syo-myj

More carefully:

• the first part sounds a bit like syo
• the stress is on the first syllable: СЬО-мий

The final -ий is not exactly like English ee. It is shorter and different in quality.

Yes. Some possible alternatives are:

• Сьомий платіж не здійснився. = The seventh payment did not happen / was not completed
• Сьомий платіж не був оброблений. = The seventh payment was not processed
• Сьомий платіж відхилили. = The seventh payment was rejected

But не пройшов is very common and natural in everyday speech, especially for payments, card transactions, and online systems.
