תדירות הטיפול כתובה בתוכנית.

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

So:

• תדירות הטיפול כתובה בתוכנית literally looks like
• frequency of-the-treatment written in-the-plan

but it means:

• The frequency of the treatment is written in the plan.

This is very normal in Hebrew.
If the sentence were in the past or future, Hebrew would use a form of to be:

• הייתה כתובה = was written
• תהיה כתובה = will be written

Because it agrees with תדירות, which is a feminine singular noun.

Hebrew adjectives and participles usually agree with the noun they describe in:

• gender
• number

Here:

• תדירות = feminine singular
• therefore כתובה = feminine singular

Compare:

• התדר כתוב = the frequency/rate is written (masculine singular)
• תדירות כתובה = the frequency is written (feminine singular)

So כתובה matches תדירות, not הטיפול.

כתובה is the passive participle of the verb לכתוב (to write).

Its basic idea is:

• written

In this sentence, it works like a predicate:

• תדירות הטיפול כתובה בתוכנית
  = The treatment frequency is written in the plan

So it is not exactly a simple past tense like was written.
It is more like a descriptive form meaning written / listed / stated.

Because תדירות הטיפול is a construct phrase (called סמיכות in Hebrew), meaning:

• the frequency of the treatment

In a construct phrase:

• the first noun usually does not take ה־
• the second noun can take ה־
• the whole phrase becomes definite because of the second noun

So:

• תדירות טיפול = frequency of a treatment / treatment frequency
• תדירות הטיפול = the frequency of the treatment

Even though תדירות has no ה־, the whole expression is definite because הטיפול is definite.

They form a noun + noun combination in the construct state:

• תדירות הטיפול

This literally means:

• frequency of the treatment

English often uses of, but Hebrew often links nouns directly instead.

Other similar examples:

• שם הילד = the name of the child
• צבע המכונית = the color of the car
• משך הטיפול = the duration of the treatment

So תדירות הטיפול is not two separate parts of the sentence. It is one unit: the subject.

Because the preposition ב־ (in) is attached directly to the noun.

So:

• ב + תוכנית → בתוכנית

This means:

• in a plan / in the plan

Since תוכנית here is definite (the plan), the combination becomes בתוכנית = in the plan.

This is very common in Hebrew. Other examples:

• בבית = in the house
• בספר = in the book
• במסמך = in the document

Hebrew often attaches short prepositions directly to the following word. The main ones are:

• ב־ = in
• ל־ = to / for
• כ־ = as / like
• מ־ = from

So instead of writing two separate words, Hebrew usually combines them:

• ב + תוכנית → בתוכנית
• ל + ילד → לילד
• מ + בית → מבית

This is standard Hebrew spelling and grammar.

Hebrew word order is often flexible, but this sentence follows a very common pattern for a present-tense nominal sentence:

• subject + description + location

Here:

• תדירות הטיפול = subject
• כתובה = predicate/descriptive element
• בתוכנית = location / where it is written

So the structure is very natural in Hebrew:

• The treatment frequency
  • is written
    • in the plan

Hebrew does not need a separate present-tense is, so the sentence can feel more compact than English.

Usually, no—that would sound unnatural in standard Hebrew.

In present-tense sentences like this, Hebrew normally does not use היא just to mean is.

The natural sentence is:

• תדירות הטיפול כתובה בתוכנית

Using הוא / היא can happen in other kinds of sentences, especially for emphasis or in equational sentences, but not normally before a participle like כתובה in this kind of sentence.

So for a learner, the best model here is simply:

• noun phrase + adjective/participle + complement

Both spellings exist.

You may see:

• תוכנית
• תכנית

They are the same word, meaning plan or program.
The spelling תוכנית is very common in modern everyday Hebrew because it is a fuller spelling.
The spelling תכנית is also standard and often appears in more formal or traditional contexts.

So if you encounter either one, do not think it is a different word.

A simple pronunciation guide is:

tdirut ha-tipul ktuva ba-tochnit

More roughly for an English speaker:

• תדירות = tdee-ROOT
• הטיפול = ha-ti-POOL
• כתובה = ktoo-VAH
• בתוכנית = ba-tokh-NEET

A more careful transliteration:

Tedirut ha-tipul ktuva ba-tokhnit.

The stress is usually near the end of each word:

• tediRUT
• hatiPUL
• ktuVA
• batokhNIT

Yes. In real usage, כתובה often means more than physically handwritten.

In a sentence like this, it can mean:

• written
• stated
• listed
• specified

So the idea is that the treatment frequency appears in the plan/document.
It does not necessarily matter whether it was handwritten, typed, printed, or entered digitally.
