У парку чотирнадцять людей.

Because у парку means in the park, and after у / в for location, Ukrainian usually uses the locative case.

• парк = park
• у парку = in the park

So the ending changes because the noun is showing location.

Ukrainian word order is fairly flexible. Starting with У парку puts the location first, a bit like:

• In the park, there are fourteen people.

This is very natural in Ukrainian. You could also hear:

• Чотирнадцять людей у парку.

but У парку чотирнадцять людей is a very normal way to present the information.

In Ukrainian, the verb є is often omitted in sentences like this, especially in the present tense.

So:

• У парку чотирнадцять людей. = There are fourteen people in the park.

Literally, it is closer to:

• In the park fourteen people.

You can sometimes say У парку є чотирнадцять людей, but in many everyday situations leaving out є sounds more natural.

Because after numerals like five and above, Ukrainian normally uses the genitive plural form of the noun.

• люди = people
• людей = of people / people (after larger numbers)

Since чотирнадцять is fourteen, the correct form is:

• чотирнадцять людей

This is one of the most important number patterns to learn in Ukrainian.

Yes. Ukrainian numbers affect the noun form in different ways.

A useful basic pattern is:

• 1 → singular
• 2, 3, 4 → a special counting form similar to nominative plural
• 5 and above → genitive plural

Examples:

• одна людина = one person
• дві / три / чотири людини = two / three / four people
• п’ять людей = five people
• чотирнадцять людей = fourteen people

So людей here follows the normal rule for 5+.

Чотирнадцять means fourteen.

Historically and structurally, it is related to:

• чотири = four
• -надцять = the -teen part

So it works a bit like English four-teen, although the exact form is not identical.

Other similar numbers are:

• одинадцять = eleven
• дванадцять = twelve
• тринадцять = thirteen
• п’ятнадцять = fifteen

Yes. У and в both often mean in.

So both of these are possible:

• У парку чотирнадцять людей.
• В парку чотирнадцять людей.

The choice is often about sound and flow, not meaning. Ukrainian alternates between у and в to avoid awkward sound combinations.

Yes, людей is the normal form here.

The dictionary form is:

• людина = person
• люди = people

After чотирнадцять, you need the genitive plural:

• людей

This is the ordinary everyday word. In more official contexts, Ukrainian might use осіб for persons, but людей is the most natural choice in a sentence like this.

Yes, it means basically the same thing:

• У парку чотирнадцять людей.
• У парку є чотирнадцять людей.

Both can mean There are fourteen people in the park.

The version without є is often more natural and common in simple present-tense statements. The version with є can sound a bit more explicit or emphatic depending on context.

A rough pronunciation guide is:

• У парку чотирнадцять людей
• u PAR-ku cho-tyr-NAD-tsyat lyu-DEY

Very rough notes:

• у = like oo in boot, but shorter
• ч = ch as in chat
• лю begins with a soft lyu sound
• stress is approximately on:
  • па́рку
  • на́ in чотирна́дцять
  • люде́й

A learner does not need perfect stress immediately, but it helps to notice it early.

In normal usage, людей simply means people. It is the standard everyday word, not something unusually biological or technical like humans.

So the natural interpretation is just:

• There are fourteen people in the park.

Not anything strange or overly formal.
