Монетоприёмник не работает.

Монетоприёмник is a noun, and here it is in the nominative case because it is the subject of the sentence — the thing that does not work.

So the sentence structure is basically:

• Монетоприёмник = the coin acceptor / coin slot / coin mechanism
• не работает = does not work / is not working

In other words: The coin acceptor doesn’t work.

In Russian, не is usually written separately from verbs.

So:

• работает = works / is working
• не работает = does not work / is not working

This is the normal rule with verbs:

• Я знаю = I know
• Я не знаю = I do not know

So не работает is exactly what you should expect.

Работает is the 3rd person singular form of работать (to work).

It matches the subject монетоприёмник, which is:

• singular
• masculine noun

So:

• монетоприёмник работает = the coin acceptor works
• монетоприёмник не работает = the coin acceptor does not work

The ending -ет is typical for this verb in the he/she/it form:

• я работаю = I work
• ты работаешь = you work
• он / она / оно работает = he / she / it works

Here English uses it, but Russian still uses the same 3rd person singular form.

Usually both are possible, depending on context.

Не работает can mean:

• doesn’t work
• is not working
• is out of order

In signs and notices, it often means something like:

• Out of order
• Not functioning

So in a machine context, Монетоприёмник не работает often means: The coin acceptor is out of order or The coin slot isn’t working.

A helpful approximate pronunciation is:

ma-nee-ta-pree-YOM-neek nye ra-BO-ta-yet

A few important points:

• ё in приёмник is pronounced yo
• the stress in приёмник is on -ём-
• the stress in работает is on БО

More carefully:

• монетоприёмник → монѐтоприёмник
• не работает → не рабо́тает

If you want a simple stress guide:

• монетоприЁмник
• раБОтает

It is a compound noun meaning something like coin receiver or coin acceptor.

It is built from parts related to:

• монета = coin
• приём = receiving / acceptance
• -ник = a common noun-forming suffix, often for a device or thing associated with an action

So монетоприёмник is the machine part that accepts coins.

Depending on context, English might translate it as:

• coin acceptor
• coin mechanism
• coin slot

Russian has no articles.

So монетоприёмник can mean:

• a coin acceptor
• the coin acceptor

The exact meaning comes from context.

That is very normal in Russian. For example:

• Это книга. = This is a book / This is the book (depending on context)
• Машина стоит там. = The car is there / A car is there

So in this sentence, English requires an article, but Russian does not.

Yes, Russian word order is fairly flexible, although Монетоприёмник не работает is the most neutral and natural order.

You might also see:

• Не работает монетоприёмник.

This can sound more like:

• The coin acceptor isn’t working
• or place a little more focus on the fact that it is not working

But for a plain statement or sign, Монетоприёмник не работает is the standard choice.

This is because Russian compound words often use a linking vowel, and the first part may appear in a stem form rather than as the full dictionary form.

Here the first word is related to монета (coin), but in the compound it becomes монето-.

So:

• монета → монето-
• plus the rest of the compound → монетоприёмник

This kind of formation is common in Russian compound nouns.

Not always. In many texts, Russians write е instead of ё, so you may see:

• монетоприемник не работает

But the intended pronunciation is still usually приёмник, with yo.

This is common in Russian spelling:

• всё is often written все
• ещё is often written еще
• приёмник is often written приемник

For learners, the dots are very helpful, so it is good to pay attention to them when they are shown.

Not exactly.

Не работает means it doesn’t work / it is not functioning. That tells you the result, but not necessarily the reason.

It could be:

• broken
• switched off
• jammed
• temporarily unavailable
• disabled by the operator

If you specifically want to say it is broken, Russian might use something like:

• сломан = broken
• сломался = broke / has broken down

But on machines, signs often prefer не работает, because it is broader and more practical.

Монетоприёмник is masculine.

You can tell because its dictionary form ends in a consonant: монетоприёмник.

That matters for agreement in some contexts, for example with adjectives:

• новый монетоприёмник = a new coin acceptor
• сломанный монетоприёмник = a broken coin acceptor

In this sentence, the verb form работает is the same for he/she/it in the present tense, so the gender does not change the verb form here. But the noun is still masculine.

No. The correct form is работает, not работаеть.

The infinitive is:

• работать = to work

But in a normal sentence with a subject, you need the conjugated form:

• монетоприёмник работает = the coin acceptor works
• монетоприёмник не работает = the coin acceptor doesn’t work

The -ть ending belongs to the infinitive, not to the present-tense form.
