Абонент підключить послугу й перевірить тарифікацію.

Ukrainian does not have articles. So Абонент can mean the subscriber or a subscriber, and послугу can mean the service or a service, depending on context.

English has to choose an article, but Ukrainian usually leaves that information to the situation, word order, or surrounding sentences.

Абонент is a noun meaning subscriber, customer, or user, especially in telecom, internet, or service-provider contexts.

In this sentence, it is the subject: the person who will do the actions.

Grammar:

• dictionary form: абонент
• case here: nominative singular
• gender: masculine

These are future-tense verb forms.

In Ukrainian, perfective verbs often form the future with a single word:

• підключить = will activate / will connect
• перевірить = will check

So unlike English, Ukrainian does not need a separate word like will here.

This gives the idea of a completed action in the future:

• first, the subscriber will activate the service
• then, the subscriber will check the billing/rating

Their infinitives are:

• підключити = to connect / to activate
• перевірити = to check / to verify

These are perfective infinitives, meaning they focus on the action as a whole or as completed.

Their imperfective partners are:

• підключати = to be connecting / to connect repeatedly
• перевіряти = to be checking / to check repeatedly

So the sentence uses perfective verbs because it talks about single completed future actions.

Because they are in the accusative case, which is used here for direct objects.

Dictionary forms:

• послуга = service
• тарифікація = billing / tariffing / charge calculation

Accusative singular forms:

• послугу
• тарифікацію

So:

• підключить послугу = will activate the service
• перевірить тарифікацію = will check the billing / charging

This is a very common feminine singular pattern:

• -а → -у
• -ія → -ію / -цію depending on the word

Й and і both mean and.

Here й is used for euphony: it sounds smoother after a vowel. Since послугу ends in a vowel sound, й helps the phrase flow more naturally:

• послугу й перевірить

Using і would still be understandable, but й sounds more natural here.

So this is mostly a pronunciation/flow choice, not a meaning difference.

Yes, very natural, especially in telecom, banking, mobile apps, and online services.

Literally, підключити is to connect, but in this kind of context it often means:

• to activate a service
• to enable a service
• to subscribe to a service

So підключити послугу is a standard real-world phrase.

Not exactly.

• тариф = a tariff, plan, rate
• тарифікація = the process or system of charging, billing, or calculating rates

So перевірити тарифікацію means something like:

• check the billing
• check how the charges are calculated
• verify the rate application

This word is somewhat technical or business-like. In everyday speech, people might sometimes use other wording depending on the context, but тарифікація is perfectly valid.

The structure is:

Абонент | підключить | послугу | й | перевірить | тарифікацію

So:

• Абонент = subject
• підключить = verb
• послугу = direct object
• й = and
• перевірить = verb
• тарифікацію = direct object

This is a normal, neutral Ukrainian word order: Subject + Verb + Object + and + Verb + Object

Yes. Ukrainian word order is more flexible than English because case endings show what each noun is doing.

For example, you could say:

• Абонент перевірить тарифікацію й підключить послугу.

That would still be grammatical, but it changes the emphasis and the order of events.

The original sentence sounds neutral and straightforward, which is why it is a good default version.

By itself, it is most naturally a statement about the future:

• The subscriber will activate the service and check the billing.

If you wanted an instruction addressed to the reader, Ukrainian would normally use the imperative:

• Підключіть послугу й перевірте тарифікацію.

So the sentence you have is not a command form; it is a future statement.
