לכל יחידה יש מספר.

לכל is made of two parts:

• ל־ = to / for
• כל = every / all

Hebrew often attaches short prepositions like ל־, ב־, and כ־ directly to the next word, so they become one written word.

So לכל יחידה literally means to every unit or for every unit.

Because Hebrew usually expresses possession with the pattern:

ל־... יש ...
literally: to ... there is ...

So:

• ליחידה יש מספר = the unit has a number
• לכל יחידה יש מספר = every unit has a number

If you remove ל־ and say כל יחידה יש מספר, it does not sound grammatical in standard Hebrew.

יש means there is / there are.

But in Hebrew, this same word is also used to express possession. So in a sentence like this, English has is usually expressed as:

ל־ + possessor + יש + thing possessed

That is why:

• לכל יחידה יש מספר

literally means:

• For every unit, there is a number

and naturally in English:

• Every unit has a number

No. In this kind of existential sentence, יש does not change for singular or plural.

For example:

• יש ספר = there is a book
• יש ספרים = there are books

So in possession sentences too, יש stays the same:

• ליחידה יש מספר = a unit has a number
• ליחידות יש מספרים = units have numbers

Because with כל, Hebrew often uses a singular noun to mean every.

So:

• כל יום = every day
• כל תלמיד = every student
• כל יחידה = every unit

If you use a plural noun, the meaning often shifts toward all rather than every:

• כל היחידות = all the units

So לכל יחידה is exactly what you expect for to every unit.

Normally, כל does not change for gender.

So you get:

• כל ספר = every book (masculine noun)
• כל יחידה = every unit (feminine noun)

The noun itself shows gender, but כל stays the same.

Because the sentence is speaking generally, not about a specific known unit or a specific known number.

• יחידה = a unit
• מספר = a number

With כל, the noun often stays without ה־:

• כל יחידה = every unit

And מספר without ה־ means a number, not the number.

If you said המספר, that would mean the number, a specific one.

Word by word:

• לכל = to every / for every
• יחידה = unit
• יש = there is
• מספר = a number

So the literal structure is:

For every unit, there is a number.

That is how Hebrew commonly says:

Every unit has a number.

Yes, this word order is very normal.

לכל יחידה יש מספר is a natural, neutral way to say it.

Hebrew often places the ל־ phrase before יש in possession sentences. That makes the possessor clear right away.

Other word orders can be possible in certain contexts, but this version is standard and straightforward for learners.

With vowel marks, it is:

לְכָל יְחִידָה יֵשׁ מִסְפָּר

A rough pronunciation guide is:

le-KHOL ye-khee-DA yesh mis-PAR

A few notes:

• ח in יחידה is a throaty kh sound, like in German Bach or Scottish loch
• Stress is usually on the last syllable of יחידה and מספר

It depends on what you want to say.

If you want units have numbers, you could say:

• ליחידות יש מספרים

If you want to keep the meaning every unit has a number, Hebrew still prefers the singular after כל:

• לכל יחידה יש מספר

So even though the meaning is distributive and refers to many units, the original sentence is already the normal way to say it.
