Паркомат не работал утром.

Работал is the past tense of работать (to work / to function / to operate).

The ending -л shows past tense, and in Russian past tense it also agrees with the subject in gender and number:

• работал = masculine singular
• работала = feminine singular
• работало = neuter singular
• работали = plural

Since паркомат is a masculine singular noun, the verb is работал.

In Russian, работать can mean not only to work as a person does, but also to function / to be operating for a machine or device.

So in this sentence:

• Паркомат работал = The parking meter was working / functioning
• Паркомат не работал = The parking meter wasn’t working

This is a very common use of работать for machines, phones, websites, elevators, etc.

In Russian, не normally goes directly before the word it negates. Here it negates the verb:

• работал = was working
• не работал = was not working

So:

• Паркомат не работал утром. = The parking meter wasn’t working in the morning.

This is the standard way to make a verb negative.

Russian has no articles, so there is no separate word for a / an / the.

That means паркомат can mean:

• a parking meter
• the parking meter

Which one sounds natural depends on context. In this sentence, English will usually use the:

• The parking meter wasn’t working in the morning.

Утром is the instrumental case form of утро (morning).

In Russian, some time expressions use the instrumental case without a preposition, especially for parts of the day:

• утром = in the morning
• днём = in the daytime / during the day
• вечером = in the evening
• ночью = at night

So утром here simply means in the morning.

Because Russian uses a special idiomatic pattern for parts of the day.

You usually say:

• утром = in the morning
• вечером = in the evening

not в утром.

В утро is not the normal way to say in the morning. Russian prefers the instrumental form by itself for this idea.

Because the sentence describes a situation at a specific time in the past: утром (in the morning).

So:

• Паркомат не работает. = The parking meter isn’t working.
• Паркомат не работал утром. = The parking meter wasn’t working in the morning.

The past tense shows that this was true earlier, not necessarily now.

Yes, this is an imperfective verb: работать.

The imperfective is used here because the sentence describes a state or ongoing condition:

• the parking meter was not functioning

It does not focus on a single completed event.

A perfective verb would change the meaning. For example, a perfective form might suggest something like stopped working or failed, rather than simply wasn’t working.

So не работал is the natural choice when you mean the machine was out of order or not functioning during that time.

Yes. Russian word order is more flexible than English, because the grammar is shown partly by endings rather than position.

The neutral order here is:

• Паркомат не работал утром.

But you could also say:

• Утром паркомат не работал.

This puts more focus on утром (in the morning), as if answering When wasn’t it working?

Both are correct, but the first version is a straightforward neutral sentence.

Yes, паркомат is masculine.

A good clue is that its dictionary form ends in a consonant:

• паркомат

Many Russian nouns ending in a consonant are masculine. That is why the past-tense verb is masculine too:

• паркомат не работал

By itself, утром usually means in the morning or in the morning time, depending on context.

Sometimes English may translate it as this morning, but that depends on the situation, not on the word alone.

For example:

• Сегодня утром = this morning
• Каждым утром = every morning
• Утром = in the morning

So in this sentence, утром is best understood as in the morning unless the wider context points to this morning.

Yes, very naturally.

Не работал can mean:

• it wasn’t functioning
• it was out of order
• it wasn’t operating

It does not always mean physically broken forever; it could have been temporarily down. But in normal use, it strongly suggests that the machine could not be used at that time.
