Я перевіряю розклад перед виходом.

Перевіряю is the 1st person singular present-tense form of the imperfective verb перевіряти.

So it means I check / I am checking, depending on context.

The imperfective aspect is used because the action is presented as:

• ongoing,
• habitual,
• or simply not focused on completion.

A perfective version would be something like перевірю from перевірити, which would suggest a completed check: I will check / I’ll check once.

That’s true: Ukrainian often leaves out subject pronouns because the verb ending already shows the person.

So Перевіряю розклад перед виходом is also perfectly natural.

Including Я can:

• add emphasis,
• make the subject especially clear,
• or slightly contrast with someone else.

So here Я is not required, but it is completely normal.

Yes, розклад is the direct object, so it is in the accusative case.

However, for many masculine inanimate singular nouns, the accusative form is identical to the nominative.

So:

• nominative: розклад
• accusative: розклад

That is why you do not see any change in form here.

Виходом is in the instrumental singular.

The preposition перед normally requires the instrumental case when it means:

• in front of, or
• before in a time sense.

So:

• перед будинком = in front of the house
• перед уроком = before the lesson
• перед виходом = before leaving / before going out

This is simply a case pattern you need to learn with the preposition перед.

This happens because the noun is вихід, but in oblique cases its stem changes:

• nominative singular: вихід
• genitive singular: виходу
• instrumental singular: виходом

This is a common vowel alternation in Ukrainian, where і in the nominative can become о or е in other forms.

You can see similar patterns in words like:

• рік → року
• стіл → столу

So виходом is the correct instrumental form.

Yes, here Ukrainian uses a noun, not a finite verb.

Вихід means something like:

• exit,
• departure,
• going out.

So перед виходом literally has the structure before the departure / before the going out, but in natural English we often express that idea with a verb: before leaving.

This noun-based structure is very common and natural in Ukrainian.

Yes. Перед тим, як вийти is also correct and natural.

The difference is mainly in structure:

• перед виходом = more compact, noun-based
• перед тим, як вийти = clause-based, more literally before (the moment when) I go out

Both are good Ukrainian. The version in your sentence is a little shorter and stylistically neat.

It can mean either, depending on context, because the present tense of an imperfective verb in Ukrainian is flexible.

It may mean:

• I check the schedule before leaving — a habit or routine
• I’m checking the schedule before leaving — something happening now

Without extra context, both readings are possible.

Yes, Ukrainian word order is fairly flexible.

For example, all of these are possible:

• Я перевіряю розклад перед виходом.
• Перед виходом я перевіряю розклад.
• Розклад я перевіряю перед виходом.

The basic meaning stays the same, but the focus changes:

• starting with перед виходом emphasizes the time,
• starting with розклад emphasizes the object,
• the original order is neutral and natural.

Розклад often means:

• schedule,
• timetable,
• itinerary, depending on context.

It is used for things like:

• train or bus times,
• class schedules,
• work timetables.

So it is a very practical everyday word. The exact English equivalent depends on what kind of schedule is being checked.
