Це п’ятий платіж.

In Ukrainian, the verb to be is usually omitted in the present tense.

So where English says This is the fifth payment, Ukrainian simply says:

• Це = this / it is
• п’ятий платіж = the fifth payment

A present-tense is is understood automatically. This is very normal in Ukrainian.

Це is a very common Ukrainian word that can mean this, that, or even it is, depending on context.

In this sentence, Це introduces identification:

• Це п’ятий платіж = This is the fifth payment

You will often see це in simple statements like:

• Це книга = This is a book
• Це мій брат = This is my brother

So here, це is functioning much like this is in English.

П’ять means five, while п’ятий means fifth.

So:

• п’ять = the number five
• п’ятий = the ordinal number fifth

Since the sentence means the fifth payment, you need the ordinal form, not the basic number.

Compare:

• п’ять платежів = five payments
• п’ятий платіж = the fifth payment

Because п’ятий is an adjective-like ordinal numeral, and it must agree with the noun it describes.

The noun платіж is:

• masculine
• singular
• nominative

So the ordinal must also be:

• masculine
• singular
• nominative

That gives you п’ятий.

If the noun changed, the ordinal would change too. For example:

• п’ятий платіж = masculine singular
• п’ята сторінка = feminine singular
• п’яте місце = neuter singular

So -ий here matches the masculine noun платіж.

They are in the nominative case.

That is because this sentence is identifying something: This is the fifth payment. The noun phrase after це is typically in the nominative.

So:

• платіж = nominative singular
• п’ятий = nominative singular masculine, matching платіж

This is the basic dictionary form of both words.

Yes, платіж means payment.

It usually refers to a payment as a transaction, installment, or amount paid in a formal or financial context.

For example, it can be used for:

• a bank payment
• a scheduled payment
• a utility payment
• an installment

So п’ятий платіж naturally means the fifth payment.

A helpful approximation is PYA-tyi, with the stress on the first syllable:

• п’я́тий

A few pronunciation notes:

• п’ means the п is followed by an apostrophe, which separates it from the я
• я here sounds roughly like ya
• The stress is on п’я́-

So it sounds approximately like PYA-tyi.

The final -ий does not sound exactly like English ee. It is a Ukrainian ending, so it is best learned by listening to native speech.

The apostrophe in Ukrainian shows that the consonant before it is not softened and that the following vowel begins with a y-like sound.

So in п’ятий:

• п stays hard
• я is pronounced more like ya

Without going too deeply into phonetics, the apostrophe helps prevent the sound from blending in the wrong way.

You will see this in other words too, for example:

• п’ять = five
• м’ясо = meat

Yes, Ukrainian word order is more flexible than English, although Це п’ятий платіж is the most neutral and natural version.

You might also encounter different word orders for emphasis, but the basic sentence is best learned as:

• Це п’ятий платіж

In beginner Ukrainian, it is safest to keep this order unless you have a reason to emphasize something.

No. Ukrainian does not have articles like a or the.

So п’ятий платіж can mean:

• the fifth payment
• sometimes just fifth payment, depending on context

English requires an article here, but Ukrainian does not.

That means you must get definiteness from context, not from a separate word.

Grammatically, є can sometimes appear, but in a simple present-tense identification sentence like this, it is usually omitted.

So the normal, natural form is:

• Це п’ятий платіж

Using є here would usually sound unnecessary or unnatural in everyday speech.

For learners, the best rule is: in present-tense sentences like This is X, Ukrainian usually leaves out is.

The ordinal would change to match the noun.

For example:

• Це п’ята сторінка = This is the fifth page
  (сторінка is feminine)

• Це п’яте місце = This is the fifth place
  (місце is neuter)

So the pattern is:

• masculine: п’ятий
• feminine: п’ята
• neuter: п’яте

That agreement is an important feature of Ukrainian grammar.
