כלבים חיים בכל העולם.

Hebrew usually does not use a present-tense form of to be.

So where English says Dogs are alive or uses are in many present-tense sentences, Hebrew often leaves it out.

In כלבים חיים בכל העולם, the word חיים already carries the idea of live / are living, so no separate are is needed.

For example:

• הכלב גדול = The dog is big
• literally: the dog big

That is normal in Hebrew.

Here חיים means live.

It comes from the verb לחיות = to live. In the present tense, Hebrew often uses forms that look like adjectives or participles. So:

• חי = living / alive
• חיים = living / alive / live, masculine plural

Because the subject is כלבים (dogs, masculine plural), חיים matches it and means live or are living.

So the structure is:

• כלבים = dogs
• חיים = live
• בכל העולם = throughout the world / all over the world

Because כלבים is plural.

In Hebrew, the present-tense verb form agrees with the subject in gender and number. Since כלבים is masculine plural, the verb form is also masculine plural:

• singular masculine: כלב חי = A dog lives / is alive
• plural masculine: כלבים חיים = Dogs live / are alive

If the subject were feminine plural, the form would usually be:

• חתולות חיות = Female cats live

Without ה־, כלבים means dogs in a general sense.

So כלבים חיים בכל העולם means something like:

• Dogs live all over the world
• Dogs are found throughout the world

This is a generic statement about dogs as a kind.

If you said הכלבים, that would usually mean the dogs — specific dogs already known from context.

So:

• כלבים חיים בכל העולם = dogs in general
• הכלבים חיים בכל העולם = the dogs live all over the world

בכל is made of two parts:

• ב־ = in
• כל = all / every

Together, בכל means something like:

• in all
• throughout
• all over

So בכל העולם is literally close to in all the world, but in natural English it is usually:

• throughout the world
• all over the world

This is a very common learner question.

In Hebrew, when כל means the whole / the entire, the noun after it is often definite.

So:

• כל העולם = the whole world
• literally: all the-world

That is standard Hebrew.

Compare:

• כלב = a dog
• כל הכלבים = all the dogs
• כל העולם = the whole world

So in בכל העולם, the phrase means throughout the whole world.

Not quite.

• בעולם = in the world
• בכל העולם = throughout the world / all over the world

So בכל העולם is stronger and more expansive. It emphasizes that dogs live in many places across the entire world, not just in the world in a general sense.

Yes, Hebrew word order is somewhat flexible, but this order is the most straightforward and natural here:

• subject: כלבים
• verb: חיים
• place phrase: בכל העולם

So:

• כלבים חיים בכל העולם

Hebrew can sometimes change word order for emphasis, but this version is the neutral, standard one.

For example, בכל העולם כלבים חיים would sound marked or poetic, not the normal everyday choice.

Yes.

חיים is the present-tense masculine plural form of לחיות.

Hebrew present tense often looks different from English because it uses participle-like forms. But functionally, here it works as the present tense:

• כלבים חיים = Dogs live
• הם חיים = They live / They are alive

A common pronunciation is:

klavim khayim b’khol ha-olam

A few notes:

• כלבים = klavim
• חיים = khayim
  The ח is a throaty sound, often written kh.
• בכל = b’khol
• העולם = ha-olam

So the full sentence sounds roughly like:

klah-VEEM kha-YEEM beh-KHOL ha-oh-LAHM

Yes, in other contexts חיים can mean alive or living, because the present-tense form and the adjective-like form are closely related.

For example:

• הכלבים חיים could mean the dogs are alive
• depending on context

But in כלבים חיים בכל העולם, the phrase בכל העולם strongly points to the meaning live:

• Dogs live all over the world

That is the natural interpretation here.
