Грудень — холодний місяць.

In Ukrainian, a dash is often used in present-tense sentences where English would use is.

So:

• Грудень — холодний місяць.
• literally: December — cold month
• natural English: December is a cold month.

Ukrainian usually does not use a present-tense verb like є in simple equational sentences like this. The dash helps show the relationship between the two parts of the sentence.

Because in Ukrainian, the present tense of to be is often omitted.

So instead of saying something like December is a cold month with an explicit verb, Ukrainian commonly just says:

• Грудень — холодний місяць.

You may sometimes see є, but in sentences like this it is usually unnecessary and often sounds less natural than the version without it.

Грудень is a noun and the name of the month December.

Grammatically:

• it is masculine
• it is singular
• here it is in the nominative case, because it is the subject of the sentence

Many month names in Ukrainian are masculine nouns, and грудень is one of them.

The adjective холодний must agree with the noun it describes.

Here it describes місяць (month), which is:

• masculine
• singular
• nominative

So the adjective also takes the masculine singular nominative form:

• холодний місяць = a cold month

Compare:

• холодний — masculine
• холодна — feminine
• холодне — neuter

Yes, you can say Грудень — холодний, and it would mean December is cold.

But Грудень — холодний місяць is slightly more explicit: December is a cold month.

So the difference is roughly:

• Грудень — холодний. = December is cold.
• Грудень — холодний місяць. = December is a cold month.

Both are grammatical, but the version with місяць names the category more clearly.

It is in the nominative case.

In this kind of sentence, both nouns are often in the nominative:

• Грудень — nominative
• місяць — nominative

That is normal in Ukrainian when one noun identifies or classifies another in a present-tense sentence like this.

A rough pronunciation guide for an English speaker is:

• Грудень ≈ HROO-denʹ
• холодний ≈ KHO-lo-dnyy
• місяць ≈ MEE-syatsʹ

A few useful notes:

• г in Ukrainian is usually like a soft English h, not a hard g
• х is like the ch in Scottish loch or German Bach
• ь is a soft sign; it does not make its own sound, but softens the consonant before it
• я in місяць contributes a ya-type sound

That is simply part of the noun’s dictionary form. Many masculine Ukrainian nouns can end in -ь or have endings like -ень in the nominative singular.

For learners, the important thing is to memorize грудень as the normal nominative form of the month name December.

When it changes case, the form may change too. For example, in the genitive it becomes:

• грудня = of December

So the word stem is not always completely unchanged across cases.

Usually, no.

In Ukrainian, names of months are normally written with a lowercase letter, unless they begin a sentence.

So in the middle of a sentence you would write:

• грудень

At the beginning of a sentence, it is capitalized only because it starts the sentence:

• Грудень — холодний місяць.

This is different from English, where December is always capitalized.

Not completely. Ukrainian word order is more flexible than English word order.

The neutral sentence is:

• Грудень — холодний місяць.

But other orders may be possible depending on emphasis. For example, changing word order can shift focus or style.

Still, for a beginner, the given version is the best one to learn first because it is clear and natural.

In this sentence, yes, it describes December as a month with cold weather.

The adjective холодний generally means cold, and it can be used in several contexts, including:

• weather: холодний день = a cold day
• objects: холодна вода = cold water
• sometimes metaphorically: холодний погляд = a cold look

Here, because the noun is місяць (month), the weather-related meaning is the natural one.

Ukrainian has no articles like English a, an, or the.

So:

• холодний місяць can mean a cold month
• and in some contexts it could also be interpreted more generally as the cold month, depending on meaning and context

In this sentence, English naturally translates it as a cold month, but Ukrainian does not mark that distinction with an article.

In isolation, the most natural meaning is December is a cold month.

Because Ukrainian has no articles, some ambiguity is theoretically possible, but context usually makes the meaning clear. Without special context, a learner should understand this sentence as a general statement about December’s weather.

So the normal interpretation is:

• December is a cold month

not

• December is the cold month

Then Ukrainian would use a form of to be.

For example:

• Грудень був холодним місяцем. = December was a cold month.
• Грудень буде холодним місяцем. = December will be a cold month.

Notice something important: in past and future versions, місяць and холодний often appear in different forms:

• холодним місяцем

This is because the grammar changes when the sentence uses an explicit verb like був or буде.
