הפיזיותרפיסט שינה את התדירות.

ה־ is the Hebrew definite article, equivalent to the in English.

So:

• פיזיותרפיסט = physiotherapist
• הפיזיותרפיסט = the physiotherapist

In this sentence, we are talking about a specific physiotherapist, not just any physiotherapist.

שינה is past tense, third person masculine singular.

So it means:

• he changed

That matches the subject הפיזיותרפיסט, which is a masculine singular noun.

A few related forms:

• שיניתי = I changed
• שינית = you changed
• שינה = he changed
• שינתה = she changed
• שינינו = we changed

Because in Hebrew, the verb itself often already tells you the person, number, and sometimes gender.

In שינה, the ending tells you this is he changed. So a separate pronoun like הוא is usually unnecessary unless you want emphasis.

For example:

• הפיזיותרפיסט שינה את התדירות = The physiotherapist changed the frequency.
• הוא שינה את התדירות = He changed the frequency.

The second version uses the pronoun הוא, but Hebrew often leaves it out when the subject is already clear.

את is the direct object marker. It appears before a definite direct object.

In this sentence:

• התדירות = the frequency
• Since it is definite, Hebrew puts את before it:
  • את התדירות

Important: את usually is not translated into English. It does not mean with here.

So:

• שינה את התדירות literally includes את, but in natural English it is just changed the frequency.

Compare:

• הוא שינה תדירות = He changed a frequency / frequency in an indefinite sense
• הוא שינה את התדירות = He changed the frequency

Just like הפיזיותרפיסט, the noun תדירות gets ה־ when it is definite.

So:

• תדירות = frequency
• התדירות = the frequency

Because the object is definite, Hebrew uses both:

• את
  • התדירות

This combination is very common in Hebrew:

• ראיתי את הספר = I saw the book
• הוא שינה את התדירות = He changed the frequency

Yes, פיזיותרפיסט is the masculine form.

A common feminine form is:

• פיזיותרפיסטית = female physiotherapist

So:

• הפיזיותרפיסט שינה את התדירות = The male physiotherapist changed the frequency.
• הפיזיותרפיסטית שינתה את התדירות = The female physiotherapist changed the frequency.

Notice that the verb changes too:

• masculine: שינה
• feminine: שינתה

This is an important feature of Hebrew: verbs in the past tense agree with the subject’s gender.

The word order here is the very common:

• Subject + Verb + Object

So:

• הפיזיותרפיסט = subject
• שינה = verb
• את התדירות = object

This is very similar to English:

• The physiotherapist changed the frequency.

Hebrew can sometimes use other word orders for style or emphasis, but this sentence is straightforward and neutral.

The dictionary form is usually given as the masculine singular past form:

• שינה

The infinitive is:

• לשנות = to change

So if you look this verb up, you may see:

• לשנות = to change

Examples:

• אני רוצה לשנות את התדירות = I want to change the frequency.
• הפיזיותרפיסט שינה את התדירות = The physiotherapist changed the frequency.

A simple pronunciation guide is:

• ha-fiz-yo-te-ra-pist shi-na et ha-tdi-rut

A smoother transliteration:

• hafizyoterapist shina et hatdirut

A few pronunciation notes:

• ה־ is pronounced like ha here.
• שינה sounds like shee-NAH.
• תדירות is roughly tdi-ROOT or teh-dee-ROOT, depending on accent and how carefully someone speaks.

Hebrew usually expresses tense directly in the verb, rather than using an extra helping verb like English sometimes does.

English can say:

• changed
• did change

Hebrew simply uses the verb form:

• שינה

So שינה already contains the meaning changed.

Not in standard Hebrew if the object is definite.

Since התדירות means the frequency, it is definite, so את is required:

• correct: הפיזיותרפיסט שינה את התדירות
• not standard: הפיזיותרפיסט שינה התדירות

If the object were indefinite, then את would normally be omitted:

• הפיזיותרפיסט שינה תדירות = The physiotherapist changed frequency / changed a frequency

But that sounds less natural in most contexts because speakers often mean a specific frequency.

Yes. תדירות is a feminine noun.

You can often tell because many feminine abstract nouns end in ־ות, as תדירות does.

This matters when adjectives or other words agree with it. For example:

• התדירות גבוהה = The frequency is high.
  (גבוהה is feminine singular.)

Even though gender does not affect the verb here, it is still useful to know the noun’s gender for other sentences.

Yes, it is natural and grammatical, especially in a medical or therapy context.

It sounds like something you might hear when talking about treatment plans, exercises, or appointments:

• הפיזיותרפיסט שינה את התדירות של התרגילים = The physiotherapist changed the frequency of the exercises.
• הפיזיותרפיסט שינה את התדירות של המפגשים = The physiotherapist changed the frequency of the sessions.

By itself, הפיזיותרפיסט שינה את התדירות is complete, though in real conversation Hebrew speakers often add what the frequency refers to.
