Реєстратура підтвердила запис.

Because the subject, реєстратура, is a feminine noun in Ukrainian.

In the past tense, Ukrainian verbs agree with the subject in gender and number:

• він підтвердив = he confirmed
• вона підтвердила = she confirmed
• воно підтвердило = it confirmed
• вони підтвердили = they confirmed

So in Реєстратура підтвердила запис, the verb is feminine singular because реєстратура is feminine singular.

Реєстратура usually means a reception desk, registration desk, or front desk, especially in a clinic, hospital, or office where appointments are managed.

So this word does not usually mean just any receptionist as a person. It often refers to the department, desk, or office itself. Ukrainian often uses the name of an office or institution as the subject of the sentence, much like English can say:

• The front desk confirmed the appointment.
• The office called me back.

Запис is the direct object, so it is in the accusative case.

But for masculine inanimate nouns, the accusative singular is often the same as the nominative singular.

So:

• nominative: запис
• accusative: запис

That is why the form does not change.

Compare this with a masculine animate noun, where the accusative would usually look different:

• лікар = doctor
• Я бачу лікаря = I see the doctor

But with an inanimate noun like запис, you get:

• підтвердити запис = to confirm the appointment/booking

In this sentence, запис most naturally means an appointment, a booking, or a registration/entry, depending on context.

In medical or office contexts, запис often means:

• appointment
• booking
• scheduled slot

So Реєстратура підтвердила запис would commonly be understood as something like:

• The front desk confirmed the appointment.
• The registration desk confirmed the booking.

The noun запис can also mean other things in other contexts, such as:

• a note
• an entry
• a record
• a recording

So context matters a lot.

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

So:

• реєстратура can mean the reception desk or just a reception desk
• запис can mean the appointment, an appointment, the booking, etc.

The exact meaning is understood from context.

The dictionary form is підтвердити, which means to confirm.

This is a perfective verb, so it usually refers to a completed action.
That fits this sentence well: the confirmation happened and is complete.

The form підтвердила is:

• past tense
• feminine singular
• completed action

This is a question of aspect, which is very important in Ukrainian.

• підтвердити = perfective, to confirm as a completed action
• підтверджувати = imperfective, to be confirming / to confirm repeatedly / in general

In Реєстратура підтвердила запис, the idea is that the confirmation happened once and was completed, so підтвердила is the natural choice.

If you used the imperfective, it would suggest a different meaning, such as an ongoing or repeated process.

No, Ukrainian word order is fairly flexible.

The neutral, straightforward order is:

• Реєстратура підтвердила запис.

But other orders are possible, depending on emphasis:

• Запис підтвердила реєстратура. = It was the reception desk that confirmed the appointment.
• Підтвердила реєстратура запис. = more marked, stylistic, or context-driven

So the original order is the most natural if you are simply stating the fact.

Potentially yes, if you look at the words by themselves, because:

• реєстратура can relate to registration/records administration
• запис can mean record, entry, note, or appointment

But in real-life usage, especially in healthcare or service contexts, the sentence most often means something like:

• The front desk confirmed the appointment.

So the exact translation depends on context, but appointment/booking is usually the most natural interpretation here.

Yes, absolutely. This is very normal.

Ukrainian often uses an institution, office, or department as the subject when that institution performs an action through its staff.

Examples:

• Школа повідомила батьків. = The school informed the parents.
• Банк підтвердив переказ. = The bank confirmed the transfer.
• Реєстратура підтвердила запис. = The front desk confirmed the appointment.

English does this too, so this part should feel fairly natural.

That would be a more passive-style idea. Ukrainian often prefers active sentences like the original one:

• Реєстратура підтвердила запис.

But you could also express the passive meaning, for example:

• Запис був підтверджений реєстратурою.

That means The appointment was confirmed by the front desk.

A learner should know, though, that the active version is often simpler and more natural in everyday Ukrainian.
