Годинник показує дванадцять.

Годинник means clock or watch. Ukrainian uses the same word for both.

So this sentence could mean:

• The clock shows twelve
• The watch shows twelve

The exact meaning depends on context.

Also, годинник is a masculine singular noun.

Because Ukrainian does not have articles like English a / an / the.

So годинник can mean:

• a clock
• the clock
• a watch
• the watch

Context tells you which one is meant.

Показує is the 3rd person singular present tense of показувати, which means to show / to display.

It matches the subject годинник:

• годинник = singular
• показує = singular he/she/it shows

So literally:

• годинник показує = the clock/watch shows

It can mean either, depending on context.

Ukrainian present tense often covers both:

• shows
• is showing

So Годинник показує дванадцять can be understood as:

• The clock shows twelve
• The clock is showing twelve

English makes this distinction more often than Ukrainian does.

Because after показує, the clock is showing a number, so Ukrainian uses the cardinal numeral дванадцять = twelve.

Compare:

• Годинник показує дванадцять.
  = The clock shows twelve.

But when simply stating the time, Ukrainian often uses an ordinal:

• Зараз дванадцята.
  = It is twelve o'clock.
• Зараз дванадцята година.
  = It is the twelfth hour / It is twelve o'clock.

So:

• дванадцять = the number twelve
• дванадцята = twelfth / used in telling the hour

Yes. It is the direct object of показує.

The clock shows what?
дванадцять

So grammatically it is in the accusative. However, with дванадцять, the accusative form looks the same as the nominative, so there is no visible ending change.

That is why it still appears as дванадцять.

It is natural if you are talking about what a clock or watch displays.

But if you simply want to say It's twelve o'clock, Ukrainians often say:

• Зараз дванадцята.
• Зараз дванадцята година.

So the sentence you have is slightly more like:

• The clock reads twelve
• The clock shows twelve

It focuses on the device, not just the time itself.

Yes, Ukrainian word order is more flexible than English.

The neutral, standard order here is:

• Годинник показує дванадцять.

That is the best version for a learner.

Other word orders are possible, but they usually add emphasis or sound more marked. For example, moving дванадцять forward could emphasize the number itself.

So for everyday use, stick with:

• Годинник показує дванадцять.

A rough English-style guide is:

ho-DYN-nyk po-KA-zu-ye dva-NA-dtsyat’

A few useful pronunciation notes:

• г in Ukrainian is usually pronounced like h, not hard English g
• є in показує sounds roughly like ye
• the final ь in дванадцять softens the final consonant

So годинник begins more like ho-, not go-.

Then the verb would also become plural:

• Годинники показують дванадцять.
  = The clocks/watches show twelve.

Compare:

• годинник показує = singular
• годинники показують = plural

This is standard subject-verb agreement.

Yes. Годинник is a general word for a timepiece.

Depending on context, it can refer to:

• a wall clock
• a desk clock
• a wristwatch

If needed, Ukrainian can be more specific, but by itself годинник is broad, just like English can sometimes use clock or watch from context.
