С новой соседкой моя жена тоже быстро ладит, хотя брат любит преувеличивать её странности.

Because the verb ладить is commonly used with с + instrumental when it means to get along with someone.

• с соседкой = with the neighbor
• с новой соседкой = with the new neighbor

So in this sentence:

• моя жена ладит с новой соседкой = my wife gets along with the new neighbor

This is just the normal pattern:

• ладить с кем? = to get along with whom?

That question с кем? requires the instrumental.

Here ладить means to get along (with someone) or to be on good terms.

It is a real and useful word, though a learner may hear хорошо ладить с кем-то especially often:

• Я с ним лажу / ладю? — actually the common present forms are a bit tricky, and many speakers avoid them.
• Мы хорошо ладим. = We get along well.
• Она ладит с детьми. = She gets along with children.

In your sentence, быстро ладит means she gets along quickly / she quickly forms a good relationship.

Yes, the current word order is flexible and natural in Russian:

• С новой соседкой моя жена тоже быстро ладит...

Russian word order is often used to manage focus and flow of information, not just grammar.

Starting with С новой соседкой puts that person in the spotlight first, almost like:

• As for the new neighbor, my wife also gets along with her quickly...

A more neutral version would be:

• Моя жена тоже быстро ладит с новой соседкой...

Both are grammatical. The original just gives a slightly different emphasis.

Тоже means also / too.

It shows that the wife is another person for whom something is true. In context, it implies that someone else also gets along with the new neighbor, or that this is one more thing happening in the situation.

Placement matters a little. Here:

• моя жена тоже быстро ладит

suggests my wife also gets along quickly.

If тоже were moved, the emphasis could shift slightly, but the core meaning would stay similar.

Because хотя introduces a subordinate clause, usually meaning although / though.

So the sentence has two parts:

1. С новой соседкой моя жена тоже быстро ладит
2. хотя брат любит преувеличивать её странности

In Russian, subordinate clauses introduced by words like хотя, когда, потому что, если are normally separated by a comma.

Literally, yes: brother loves to exaggerate. But in natural English, it often means:

• the brother tends to exaggerate
• the brother likes exaggerating
• the brother has a habit of exaggerating

Russian often uses любить + infinitive not only for literal love, but also for a habitual tendency:

• Он любит спорить. = He likes to argue / He tends to argue.
• Она любит жаловаться. = She likes complaining / She tends to complain.

So here it probably means the brother has a habit of making her oddities sound bigger than they are.

Because the sentence describes a general habit or tendency, not one completed act.

• преувеличивать = imperfective = to exaggerate, to be in the habit of exaggerating
• преувеличить = perfective = to exaggerate once / to overstate something in a completed way

With любит + infinitive, the imperfective is often the natural choice when talking about repeated behavior:

• любит опаздывать = tends to be late
• любит преувеличивать = tends to exaggerate

If you used the perfective here, it would sound less natural for this meaning.

Странности is in the accusative plural because it is the direct object of преувеличивать.

• преувеличивать что? = to exaggerate what?
• её странности = her oddities / her quirks

Since странности is an inanimate plural noun, its accusative plural looks the same as the nominative plural:

• nominative plural: странности
• accusative plural: странности

So even though the form looks unchanged, the function is accusative here.

Here её means her.

Specifically, it is a possessive/genitive-type form used before a noun:

• её странности = her oddities

About spelling: Russian often omits the dots and writes ее instead of её in ordinary texts. Both refer to the same word, but ё is more precise.

So you may see:

• её странности
• ее странности

Both mean the same thing.

Plural странности means odd traits, quirks, unusual behaviors. This is very natural in Russian.

• её странности = her quirks / her oddities

A singular form would be possible only if you meant one specific odd thing:

• её странность = her oddity / one strange trait

But when talking generally about a person’s unusual characteristics, the plural is more idiomatic.

Yes, быстро literally means quickly. Here it modifies ладит and means that the wife quickly establishes good relations with the new neighbor.

So:

• быстро ладит = gets along quickly / quickly gets on well

In English, this may sound slightly more natural as:

• gets along with her quickly
• quickly hits it off with her

depending on context.

Russian has no articles like a or the.

So новой соседкой can mean:

• with a new neighbor
• with the new neighbor

The exact interpretation comes from context. Since your English meaning is already known, the learner just needs to remember that Russian does not mark this with an article.

Yes. Depending on tone and context, хотя can be translated as:

• although
• though
• even though

In this sentence, all are possible in English. The basic idea is contrast:

• the wife gets along with the new neighbor
• but the brother tends to exaggerate the neighbor’s quirks

So хотя introduces a concessive contrast.
