Священник вошёл в церковь.

Священник is in the nominative case because it is the subject of the sentence — the person performing the action.

Its dictionary form is also священник, so nothing changes here.

• священник = priest
• nominative singular masculine

In this sentence, it means the priest or a priest, depending on context.

This is a very common question because в can be used with different cases.

Here, в means into, showing motion toward the inside of a place, so Russian uses the accusative case.

• в церковь = into the church
• в церкви = in the church

So:

• Священник вошёл в церковь = The priest entered the church.
• Священник был в церкви = The priest was in the church.

A helpful rule:

• motion into a place → в + accusative
• location inside a place → в + prepositional

Yes. Церковь is one of those nouns whose accusative singular looks the same as the nominative singular.

Its forms are:

• nominative: церковь
• accusative: церковь
• prepositional: церкви

So even though the form does not change visibly here, the case is still accusative because the preposition в with motion requires it.

This happens because церковь is an inanimate feminine noun of the third declension.

Вошёл means entered / went in, while шёл means was going / was walking.

So the difference is about both meaning and aspect:

• идти / шёл = to go on foot, to be going, to be walking
• войти / вошёл = to enter, to go in

Вошёл is the past tense masculine singular form of войти, which is a perfective verb. Perfective verbs usually focus on a completed action.

So:

• Священник шёл в церковь = The priest was walking to church.
• Священник вошёл в церковь = The priest entered the church.

The prefix в- adds the idea of going into something.

Compare:

• идти = to go, to walk
• войти = to go in, to enter
• past masculine: вошёл

Russian uses prefixes very often to create more specific meanings from basic verbs of motion.

Here, the core idea is:

• base motion verb: идти
• prefixed form: войти = enter

So вошёл в церковь literally has the sense of went in into the church, though in English we simply say entered the church.

Yes, it is somewhat irregular, and learners often notice that.

The infinitive is войти, but the past tense masculine form is вошёл.

This comes from an older stem change found in common Russian motion verbs. You do not need to fully predict it at first — it is best learned as a pattern.

Useful forms:

• infinitive: войти
• past masculine: вошёл
• past feminine: вошла
• past neuter: вошло
• plural: вошли

So if the subject changes:

• Священник вошёл
• Женщина вошла
• Окно? not likely semantically, but grammatically вошло
• Люди вошли

Because the subject is masculine singular and the sentence is in the past tense.

In Russian past tense, the verb agrees with the subject in gender and number:

• masculine: вошёл
• feminine: вошла
• neuter: вошло
• plural: вошли

Since священник is masculine singular, the verb must be вошёл.

The stress is:

• свяще́нник
• вошёл
• це́рковь

So the whole sentence is pronounced approximately:

свяще́нник вошёл в це́рковь

A couple of helpful pronunciation notes:

• ё in вошёл is always stressed.
• в before ц is pronounced like f in connected speech, so в церковь sounds roughly like ф це́рковь.
• The cluster in священник is difficult at first; say it slowly: свя-ще́н-ник.

Russian has no articles like English the and a/an.

So Священник вошёл в церковь could mean:

• The priest entered the church
• A priest entered a church
• The priest entered a church
• A priest entered the church

Context tells you which meaning is intended.

In many situations, English speakers want Russian to mark definiteness clearly, but Russian usually leaves that to context, word order, or the broader situation.

Yes. Russian word order is more flexible than English word order because the cases show grammatical roles.

The neutral order here is:

• Священник вошёл в церковь.

But you could also say:

• В церковь вошёл священник.

That still means the same basic thing, but the emphasis changes a little. This version can sound like:

• Into the church entered a priest
• or more naturally, A priest entered the church with focus on who entered

So word order in Russian often affects focus and information structure, not just grammar.

Yes. Вошёл в церковь can be translated naturally as either:

• entered the church
• went into the church

The Russian sentence itself does not force only one of those English versions. English translators choose the one that sounds best in context.

Both can be translated as church, but they are not always identical in usage.

• церковь usually means a church building, and can also mean the Church as an institution in some contexts
• храм means temple or church building, often with a somewhat more formal, elevated, or architectural feel

In this sentence, церковь is the most ordinary and natural word for church.

Yes. It is a completely natural and grammatically complete Russian sentence.

It has:

• a subject: Священник
• a verb: вошёл
• a destination/place of motion: в церковь

It sounds like a normal simple narrative sentence, the kind you might see in a story or textbook.

Not always in everyday writing. Very often you will see вошел written with е instead of ё.

So both may appear:

• вошёл — fully marked, clearer for learners
• вошел — common in ordinary printed text

But the word is still pronounced вошёл, with ё.

For learners, it is very useful to remember the ё, because it helps with both pronunciation and stress.
