Ремень для переноски готов, а разборка мебели началась.

Готов is the short form of the adjective готовый.

In Russian, short-form adjectives are very commonly used:

• as the predicate of the sentence
• especially for temporary states or conditions

So:

• Ремень готов = The strap is ready
• готовый ремень = a ready/finished strap (used before a noun as a description)

Here, готов agrees with ремень, which is:

• masculine
• singular

That is why the form is готов.

Other forms would be:

• готова for feminine
• готово for neuter
• готовы for plural

In Russian, the verb to be is normally not expressed in the present tense.

So where English says:

• The strap is ready

Russian simply says:

• Ремень готов

This is completely normal. Russian often leaves out is / are / am in present-tense statements.

But in the past or future, forms of быть do appear:

• Ремень был готов = The strap was ready
• Ремень будет готов = The strap will be ready

Для means for, and it requires the genitive case.

The noun переноска means carrying, transporting, or a carrying action/device, depending on context.
Here it is a verbal noun: the act/purpose of carrying.

So:

• для переноски = for carrying / for transport

Because для takes the genitive, переноска becomes переноски.

This structure is very common in Russian:

• сумка для книг = bag for books
• машина для уборки = machine for cleaning
• инструмент для резки = tool for cutting

Russian often uses a noun after для instead of an infinitive.

English can say:

• for carrying

Russian often prefers:

• для переноски literally for carrying / for the carrying

Using для + verbal noun is very natural in Russian.

The infinitive переносить means to carry / to transport, but after для, Russian usually wants a noun phrase, not a bare infinitive.

So для переноски is the normal structure here.

Разборка is a noun meaning disassembly / taking apart.

When Russian uses action nouns like this, the thing being acted on is very often put in the genitive case.

So:

• разборка мебели = the disassembly of the furniture

Here:

• разборка = disassembly
• мебель = furniture
• мебели = genitive form, meaning of the furniture

This is similar to other Russian noun phrases:

• чтение книги = reading of the book
• ремонт машины = repair of the car
• сборка шкафа = assembly of the wardrobe/cabinet

The verb началась is past tense, and in Russian past tense it agrees with the subject in gender and number.

The subject here is разборка, which is:

• feminine
• singular

So the verb must also be feminine singular:

• начался = masculine
• началась = feminine
• началось = neuter
• начались = plural

That is why we get:

• разборка ... началась

The verb here is начаться, not начать.

• начать = to begin/start something
• начаться = to begin/start (by itself, without a direct object)

Compare:

• Они начали разборку мебели. = They began the disassembly of the furniture.
• Разборка мебели началась. = The disassembly of the furniture began.

So the reflexive form начаться is used because разборка мебели itself is what began.

Both а and и can connect clauses, but they are not exactly the same.

• и = simple and
• а = and / while / whereas / as for, often with a slight contrast or shift of focus

In this sentence, а suggests that the speaker is presenting a second fact alongside the first, with a mild contrast or separation:

• The carrying strap is ready, and meanwhile / while that’s the case, the furniture disassembly has begun.

So а sounds more natural than plain и if the speaker wants to connect two related but distinct developments.

Because а is joining two separate clauses, and Russian normally puts a comma before coordinating conjunctions like а when they connect full clauses.

The two clauses are:

1. Ремень для переноски готов
2. разборка мебели началась

Since each part has its own grammatical center, a comma is required.

Ремень is in the nominative case.

It is the subject of the first clause:

• Ремень ... готов = The strap ... is ready

In Russian, the nominative is typically used for:

• the subject of the sentence
• dictionary form of a noun

So here ремень is simply the thing being described as ready.

Sometimes Russian has two related nouns like this, but they are not always interchangeable.

• разборка commonly means taking apart / dismantling / disassembly
• разбор often means analysis, sorting out, review, or in some contexts taking apart, but it has a broader and different range of meanings

For furniture, разборка мебели is the natural phrase for disassembly of furniture.

So a learner should treat разборка мебели as the standard expression here.

The word order is quite normal and neutral.

• Ремень для переноски готов
• разборка мебели началась

Russian word order is more flexible than English, but this sentence uses a straightforward pattern:

• subject + modifiers + predicate

You could move words around for emphasis, but the given order sounds natural and unmarked.

For example, Готов ремень для переноски would sound more emphatic or stylistically marked, not the basic neutral order.
