Они обсуждают брак.

Они means they. It is the 3rd person plural pronoun.

So in Они обсуждают брак, the subject is they — some group of people who are discussing something.

A useful note for English speakers: Russian pronouns change for case, but here они is in the nominative case because it is the subject of the sentence.

Обсуждают is the verb обсуждать in the present tense, 3rd person plural.

Breakdown:

• обсуждать = to discuss
• обсуждают = they discuss / they are discussing

The ending -ют shows that the subject is they.

So:

• я обсуждаю = I discuss
• ты обсуждаешь = you discuss
• он/она обсуждает = he/she discusses
• они обсуждают = they discuss

In this sentence, the verb agrees with они.

It can mean both, depending on context.

Russian present tense often covers both:

• They discuss marriage
• They are discussing marriage

In English, we often choose between simple present and present continuous, but Russian usually just uses one present-tense form.

So Они обсуждают брак could describe:

• something happening right now, or
• a more general action

Context tells you which meaning is intended.

Good question. Брак is the direct object, so it is in the accusative case.

However, брак is:

• masculine
• inanimate
• singular

For many masculine inanimate nouns, the accusative singular is the same as the nominative singular.

So:

• nominative: брак
• accusative: брак

That is why the form does not change.

Compare this with an animate masculine noun, where accusative often looks like the genitive instead.

Обсуждать is the imperfective verb.

That means it is used for:

• ongoing actions
• repeated actions
• general processes

So Они обсуждают брак presents the action as a process: they are in the middle of discussing it, or they discuss it in general.

The perfective partner is usually обсудить:

• Они обсуждают брак = They are discussing marriage / They discuss marriage.
• Они обсудят брак = They will discuss marriage.
• Они обсудили брак = They discussed marriage and finished discussing it.

This aspect contrast is very important in Russian.

No, Russian word order is more flexible than English word order.

The neutral, straightforward order is:

• Они обсуждают брак.

But you could also hear:

• Брак они обсуждают.
• Обсуждают они брак.

These alternatives can sound more marked and may change the focus or emphasis, not the basic meaning.

For a learner, the safest default is:

• subject + verb + object

So Они обсуждают брак is the most natural neutral version.

Yes, often it can.

Russian frequently drops subject pronouns when the verb ending already makes the subject clear.

So in context, you might hear:

• Обсуждают брак.

Because обсуждают already shows 3rd person plural, the listener may understand they from context.

Still, они is often included when:

• the subject is being introduced
• you want emphasis
• there could be confusion

So both are possible:

• Они обсуждают брак.
• Обсуждают брак.

No. Брак can also mean defect or faulty goods.

So depending on context:

• брак = marriage
• брак = defect / manufacturing flaw

That can surprise learners, because the two meanings are very different.

In real life, context usually makes it clear:

• обсуждают брак could mean they are discussing marriage
• but in an industrial or business context, it could mean they are discussing defective products

So this is a useful vocabulary warning: брак is an ambiguous word.

Russian does not have articles like a, an, or the.

So брак can mean:

• marriage
• a marriage
• the marriage

Which one sounds best depends on context and on the translation already given to the learner.

English speakers often look for an article, but in Russian there usually isn’t one. Instead, definiteness is understood from:

• context
• word order
• intonation
• the broader situation

The main stress pattern is:

• они́
• обсужда́ют
• брак

So the sentence is pronounced approximately:

• ani obsoozh-DYE-yut brak

A few pronunciation tips:

• о in unstressed position is reduced, so it may sound closer to a or a weak uh
• жд/ждa-type spelling here is pronounced with a zh sound in обсуждают
• брак is one syllable, so it is naturally stressed

You do not need to pronounce every letter exactly like in English spelling; stress and vowel reduction matter a lot in Russian.

Yes.

Because обсуждают is imperfective present, the sentence can mean either:

• They are discussing marriage right now, or
• They discuss marriage as a general topic

For example:

• At a table right now: Они обсуждают брак.
• In a sociology class in general: Они обсуждают брак.

Russian often leaves this distinction to context, whereas English usually makes it more explicit.
