Fizjoterapia zaczyna się po wizycie.

In this sentence, się is part of the verb phrase zaczynać się, which means to begin / to start when something starts by itself.

Compare:

• Zaczynam fizjoterapię. = I am starting physiotherapy.
  
  • Here zaczynać is transitive: someone starts something.
• Fizjoterapia zaczyna się po wizycie. = Physiotherapy starts after the appointment.
  
  • Here zaczynać się is intransitive: the thing itself begins.

So się often does not need a separate English word. It just helps make the verb mean starts/begins rather than starts something.

Because the preposition po normally requires the locative case when it means after.

The noun wizyta is the dictionary form, called the nominative. After po, it changes:

• wizyta → nominative
• po wizycie → locative

So:

• po obiedzie = after lunch
• po pracy = after work
• po wizycie = after the appointment / after a visit

This is one of the most common things learners need to memorize in Polish: certain prepositions force certain cases.

Not really. It is a normal case change for a feminine noun ending in -a.

The noun is:

• wizyta = appointment / visit

In the locative singular, it becomes:

• wizycie

Many feminine nouns behave similarly:

• ulica → na ulicy
• kawa → o kawie
• wizyta → po wizycie

So it may look unfamiliar at first, but it follows a common pattern.

Because the subject is fizjoterapia, which is a singular noun.

• fizjoterapia = singular
• therefore zaczyna się = starts

If the subject were plural, the verb would also be plural:

• Zajęcia zaczynają się po wizycie. = The classes start after the appointment.

In the present tense, Polish verbs agree with the subject in number and person. In past tense they also show gender, but here we are in the present tense, so zaczyna is simply the 3rd person singular form.

Grammatically, zaczyna się is present tense.

However, in Polish, the present tense of an imperfective verb can be used for:

• general statements
• repeated situations
• schedules or planned events

So this sentence can sound like:

• a general rule: Physiotherapy begins after the appointment
• part of a schedule: Physiotherapy starts after the appointment

If you wanted a more clearly one-time future meaning, Polish often uses the perfective verb:

• Fizjoterapia zacznie się po wizycie. = Physiotherapy will start after the appointment.

So both are possible, but they are used a bit differently.

Because Polish has no articles. There is no direct equivalent of a / an / the.

So po wizycie could mean:

• after the appointment
• after an appointment
• after the visit

The exact meaning depends on context.

If you want to make it more specific, Polish can add words like:

• po tej wizycie = after this appointment
• po pierwszej wizycie = after the first appointment
• po wizycie u lekarza = after the doctor’s appointment / after the visit to the doctor

Yes. Polish word order is more flexible than English word order.

The sentence:

• Fizjoterapia zaczyna się po wizycie.

is a neutral, natural order.

But you could also say:

• Po wizycie zaczyna się fizjoterapia.

This puts more focus on after the appointment.

Both are correct. The difference is usually about emphasis, rhythm, or what information is already known in the conversation.

Yes. That is also correct.

• zaczyna się = starts / begins
• rozpoczyna się = begins / commences

The difference is mostly one of style:

• zaczyna się sounds very common and everyday
• rozpoczyna się sounds a bit more formal or official

So in normal speech, zaczyna się is often the more natural choice.

A rough English-style approximation is:

fee-zyo-teh-RAH-pya za-CHI-na shyeh po vee-ZY-cheh

A few useful notes:

• fizjo- sounds like fizyo-
• cz sounds like English ch, but harder
• się is usually pronounced close to shyeh
• wi in wizycie sounds like vee
• stress in Polish is usually on the second-to-last syllable

So:

• fizjoteraPIa
• zaCZYna
• wiZYcie

When translating into English, no. English nouns usually do not have grammatical gender in the same way.

But in Polish, fizjoterapia is grammatically feminine because it ends in -a. That matters for grammar, even if it does not change the English meaning.

For example, in the past tense:

• Fizjoterapia zaczęła się po wizycie.

The form zaczęła shows feminine singular agreement with fizjoterapia.

So gender is important inside Polish grammar, even when it is not visible in English translation.
