من همیشه قبل از خواب کامپیوتر را خاموش میکنم.

Yes. In natural Persian, من is often omitted because the verb ending already shows the subject.

• می‌کنم means I do
• the -م ending tells you it is I

So this sentence could also be:

همیشه قبل از خواب کامپیوتر را خاموش می‌کنم.

Adding من makes the subject a little more explicit. It can sound like:

• As for me, I always turn off the computer before sleeping
• or it may simply add slight emphasis

Because Persian normally uses Subject–Object–Verb word order.

In this sentence:

• من = I
• همیشه قبل از خواب = always before sleep / before going to sleep
• کامپیوتر را = the computer
• خاموش می‌کنم = turn off

So Persian puts the main verb at the end, unlike English.

A very literal order would be:

I always before sleep the computer turn off.

That is completely normal in Persian.

همیشه means always.

It is an adverb of frequency, and in Persian it often appears before the time phrase or before the verb phrase. In this sentence, it comes early:

من همیشه قبل از خواب کامپیوتر را خاموش می‌کنم.

That placement is very natural.

You may also hear slightly different word orders in real speech, but this one is standard and common.

Literally, it means before sleep.

Breakdown:

• قبل = before
• از = from / of / before in this fixed expression
• خواب = sleep

So قبل از خواب is a set phrase meaning:

• before sleep
• before going to bed
• before sleeping

In natural English, we usually translate it more smoothly as before going to sleep or before bed, depending on context.

Because قبل از is the normal Persian pattern for before when followed by a noun or noun-like expression.

So Persian says:

• قبل از خواب = before sleep
• قبل از غذا = before food / before the meal
• قبل از کلاس = before class

You should learn قبل از as a chunk.

There is also قبلِ in some contexts, but for learners, قبل از + noun is the safest and most useful pattern.

را marks the direct object, especially when it is specific or definite.

Here:

• کامپیوتر را = the computer as the thing being turned off

So را tells you that کامپیوتر is the object of the verb.

This is one of the most important particles in Persian.

Compare:

• کتاب می‌خوانم = I read books / I am reading a book
• کتاب را می‌خوانم = I am reading the book / I read the specific book

In your sentence, the speaker is talking about a specific computer, so را is natural.

Because this is a very common Persian compound verb.

It is made of:

• خاموش = off / extinguished / silent
• کردن = to do

Together, خاموش کردن means to turn off.

In the sentence, کردن is conjugated:

• می‌کنم = I do / I turn
• so خاموش می‌کنم = I turn off

Persian uses many compound verbs like this. The nonverbal part comes first, and the conjugated verb comes after it.

Examples:

• باز می‌کنم = I open
• تمیز می‌کنم = I clean
• روشن می‌کنم = I turn on

Here می‌کنم is in the simple present, but in this context it expresses a habitual action.

So it means:

• I turn off
• or more naturally, I always turn off

Because the sentence includes همیشه, the habitual meaning is very clear.

Structure:

• می- = present/imperfective marker
• کن = present stem of کردن
• -م = I

So می‌کنم literally has the structure of I do / I am doing, but in this sentence it is best understood as I usually / always do.

Its basic meaning is to turn off, switch off, or extinguish.

It is commonly used with things like:

• lights
• computers
• TVs
• machines
• engines

Examples:

• چراغ را خاموش می‌کنم = I turn off the light
• تلویزیون را خاموش می‌کنم = I turn off the TV

It can also mean extinguish in contexts like fire or a cigarette.

So in your sentence, کامپیوتر را خاموش می‌کنم very naturally means I turn off the computer.

A natural pronunciation is:

man hamishe ghabl az khâb kâmpiuter râ khâmush mikonam

A more careful breakdown:

• من = man
• همیشه = hamishe
• قبل از = ghabl az
• خواب = khâb
• کامپیوتر = kâmpiuter
• را = râ
• خاموش می‌کنم = khâmush mikonam

A few pronunciation notes:

• خ sounds like the ch in German Bach or Scottish loch
• ق in modern Persian is often pronounced like a voiced back fricative; many learners approximate it with gh
• خواب has a long â
• را in speech can be shortened, and in colloquial Persian it often sounds like ro

So colloquially, you may hear something like:

man hamishe ghabl az khâb kâmpiuter-o khâmush mikonam

Both are seen, but می‌کنم is the standard modern spelling.

The standard form uses:

• می‌
  • verb
• with a small joiner called a half-space

So the standard spelling is:

خاموش می‌کنم

In less careful typing, many people write:

خاموش میکنم

It means the same thing. As a learner, it is best to learn and write the standard form می‌کنم.

It is a borrowed word, basically the Persian form of computer.

It is very common and completely normal in Persian.

Pronunciation is roughly:

kâmpiuter

You may also see or hear other technology words borrowed into Persian, especially in everyday speech.

Not literally. خواب means sleep, not bed.

But in English, before bed is a very natural translation of قبل از خواب in many contexts.

So:

• literal sense: before sleep
• natural English: before bed or before going to sleep

This is a good example of how the most natural translation is not always word-for-word.

In standard Persian, with a specific object like the computer, را is expected.

So:

• کامپیوتر را خاموش می‌کنم = standard and correct

If you remove را, the sentence sounds less precise or less standard in this context.

In colloquial speech, را often changes in pronunciation to رو, but it usually does not disappear completely when the object is specific.

For example, in speech:

کامپیوتر رو خاموش می‌کنم

That is very common conversational Persian.

Yes, a few alternatives are possible, but قبل از خواب is one of the most common.

Other possibilities include:

• پیش از خواب = before sleep, a bit more formal/literary
• قبل از اینکه بخوابم = before I go to sleep

Your sentence with قبل از خواب is simple, natural, and very useful for everyday Persian.

A very natural spoken version would often be:

من همیشه قبلِ خواب کامپیوترُ خاموش می‌کنم.

Or in transliteration:

man hamishe ghabl-e khâb kâmpiuter-o khâmush mikonam

Common colloquial changes include:

• را becoming رو / ـو
• slight smoothing of قبل از in fast speech
• less careful pronunciation overall

But for learning and writing, the standard sentence is excellent:

من همیشه قبل از خواب کامپیوتر را خاموش می‌کنم.
