הקולר אדום.

In Hebrew, the verb to be is usually not expressed in the present tense.

So הקולר אדום literally looks like the collar red, but it means the collar is red.

This is completely normal in Hebrew:

• הילד עייף = The boy is tired
• הדלת פתוחה = The door is open

In the past or future, Hebrew does use a form of to be:

• הקולר היה אדום = The collar was red
• הקולר יהיה אדום = The collar will be red

Because in Hebrew, adjectives normally come after the noun.

So:

• קולר אדום = a red collar
• הקולר אדום = the collar is red / literally the collar red

This is the normal Hebrew order:

• noun first
• adjective second

That is different from English, where adjectives usually come before the noun.

The prefix ה־ is the Hebrew definite article, meaning the.

So:

• קולר = a collar / collar
• הקולר = the collar

Hebrew attaches the directly to the beginning of the noun instead of using a separate word like English does.

Because קולר is a masculine singular noun, and Hebrew adjectives must agree with the noun in gender and number.

So:

• masculine singular: אדום
• feminine singular: אדומה
• masculine plural: אדומים
• feminine plural: אדומות

Since קולר is masculine singular, אדום is the correct form.

Yes. Agreement still happens exactly the same way.

In הקולר אדום, אדום is a predicate adjective, but it still matches הקולר in gender and number.

Compare:

• הקולר אדום = masculine singular
• החולצה אדומה = feminine singular
• הקולרים אדומים = masculine plural
• החולצות אדומות = feminine plural

So the missing present-tense is does not change adjective agreement.

This is a very important difference.

• הקולר אדום = The collar is red
  This is a full sentence.

• הקולר האדום = the red collar
  This is usually just a noun phrase, not a complete sentence.

Why? Because when an adjective is attributive (directly describing a noun inside a noun phrase), it usually takes ה־ too if the noun is definite:

• הקולר האדום = the red collar

But in a sentence like הקולר אדום, the adjective is a predicate, so it does not take ה־.

It is pronounced approximately:

ha-ko-LAR a-DOM

A more careful breakdown:

• הקולר = ha-ko-LAR
• אדום = a-DOM

The stress is normally on the last syllable of each word.

קולר is masculine.

In this sentence, one clue is the adjective אדום, which is masculine singular. But in general, you often need to learn the gender of each noun from usage or a dictionary.

The definite article ה־ does not tell you gender, because it is used with both masculine and feminine nouns.

In normal everyday Hebrew, הקולר אדום is the standard way.

Putting אדום first would sound unusual, poetic, or highly marked in most contexts. A learner should treat noun + adjective here as the normal pattern.

So for ordinary speech, use:

• הקולר אדום

Yes. Even though there is no separate word for is, the sentence is understood as present tense.

So:

• הקולר אדום = present: The collar is red
• הקולר היה אדום = past: The collar was red
• הקולר יהיה אדום = future: The collar will be red

This is one of the most basic and common Hebrew sentence patterns.
