Приём посылок и юридический адрес важны для резидента коворкинга.

In Russian, the verb to be is usually omitted in the present tense. So:

• Приём посылок и юридический адрес важны
  literally corresponds to
• Parcel reception and a legal address are important

Russian does not normally say a separate word for are here. The meaning is understood automatically.

Because the sentence has a compound subject: two things are being talked about together:

• приём посылок
• юридический адрес

When two singular nouns are joined by и (and), Russian normally uses a plural predicate. So важны means are important for both items together.

Важны is the short form of the adjective важный. In Russian, short-form adjectives are very commonly used when the adjective is the main predicate of the sentence, especially in sentences like X is important, Y is necessary, Z is ready, and so on.

So:

• важны = are important
• важные = important as a full adjective, usually before a noun, as in важные документы (important documents)

Here, важны is the natural predicative form.

Because приём посылок means the receiving/acceptance of parcels. After many verbal nouns like приём (reception, acceptance, receiving), the thing being received is often put in the genitive.

So:

• приём чего? — посылок

This is similar to English reception of parcels or acceptance of parcels.

It is also plural because the idea is general: not one parcel, but parcels in general.

Because приём names the service, process, or activity of receiving parcels, not one separate act per parcel. It is an abstract noun here.

So приём посылок means something like:

• parcel reception
• accepting parcels
• receipt of parcels

The singular refers to the overall concept, not to the number of parcels.

Резидента is in the genitive singular because it comes after the preposition для (for).

The preposition для always takes the genitive:

• для кого? чего? — для резидента

So для резидента means for the resident/member.

Here коворкинга depends on резидента and means of the coworking space.

So:

• резидент коворкинга = resident/member of the coworking space

This is a common noun + genitive pattern in Russian, similar to:

• директор компании = director of the company
• член клуба = member of the club

So коворкинга is genitive singular because it answers resident of what?

Literally, yes, резидент is related to resident, but in business or coworking contexts it often means something closer to:

• member
• tenant
• registered user
• occupant

So резидент коворкинга may sound more natural in English as a coworking member or someone based in the coworking space, depending on context.

Russian has no articles like a, an, or the. That means nouns often appear without any word corresponding to an English article.

So:

• юридический адрес could mean a legal address or the legal address
• резидента коворкинга could mean a coworking resident/member or the coworking resident/member

The exact interpretation depends on context.

Yes. Russian word order is more flexible than English because case endings show the grammatical relationships.

This sentence has a neutral, straightforward order:

• Приём посылок и юридический адрес важны для резидента коворкинга.

But you could also say:

• Для резидента коворкинга важны приём посылок и юридический адрес.

That version puts more emphasis on for the coworking resident/member.

The basic meaning stays the same, but the focus can shift.

It is a noun phrase built from:

• приём = reception / acceptance / receiving
• посылок = of parcels

Together, it means parcel reception, receipt of parcels, or accepting parcels.

This kind of structure is very common in Russian, especially in formal or business language: a noun expressing an action plus a genitive noun expressing the object of that action.

It is very important for pronunciation and stress. Приём is pronounced with ё, and ё always carries the stress.

So the stress is on the last syllable:

• приём

In many printed texts, ё is sometimes written as е, so you may see прием, but it is still pronounced приём. For learners, it is helpful to remember the ё even when it is not written.
