بعضی وقت ها فقط میخواهم کنار دریا بنشینم و به صدای آب گوش بدهم.

Yes. In standard modern Persian, you will often see this written as بعضی وقت‌ها with a half-space before ها.

Breakdown:

• بعضی = some
• وقت = time
• ها = plural marker

So literally it is something like some times.

Common spellings:

• بعضی وقت ها — fully separated, very common in casual typing
• بعضی وقت‌ها — more standard
• بعضی‌وقت‌ها — sometimes written with a half-space between بعضی and وقت‌ها too, treating the whole phrase almost like a set expression

A learner should recognize all of these as the same phrase.

You are right. The more standard spelling is:

می‌خواهم

with a half-space between می and the verb stem.

Many people type it without the half-space:

• میخواهم

Both are very common, but می‌خواهم is the more careful written form.

This same issue happens with many verbs:

• می‌روم / میروم
• می‌نویسم / مینویسم

So if you are learning to read Persian, get used to seeing both styles.

After خواستن in the sense of to want, Persian normally uses the subjunctive form for the following verb.

So:

• می‌خواهم بنشینم = I want to sit
• می‌خواهم گوش بدهم = I want to listen

That is why you see:

• بنشینم
• بدهم

instead of indicative forms like:

• می‌نشینم = I sit / I am sitting
• می‌دهم = I give / I do give

This is a very important pattern in Persian:

• می‌خواهم بروم = I want to go
• می‌خواهم بخوانم = I want to read
• می‌خواهم بخوابم = I want to sleep

So in this sentence, both actions after می‌خواهم are in the subjunctive.

Because بنشینم is the normal subjunctive form of نشستن (to sit).

The بـ at the beginning is a common marker in subjunctive and imperative forms.

Compare:

• نشستن = to sit
• می‌نشینم = I sit / I am sitting
• بنشینم = that I sit / for me to sit / I sit, after a verb like want

Similarly:

• رفتن = to go
• می‌روم = I go
• بروم = I go, in subjunctive contexts such as می‌خواهم بروم

So بنشینم here is exactly what you would expect after می‌خواهم.

Yes, by itself دادن means to give, but گوش دادن is a fixed expression meaning to listen.

Literally, it may feel strange to an English speaker, but you should learn it as a whole unit:

• گوش دادن = to listen

Examples:

• به موسیقی گوش می‌دهم = I listen to music
• به حرفش گوش بده = Listen to what he says
• دوست دارم به صدای باران گوش بدهم = I like to listen to the sound of rain

So in your sentence, گوش بدهم is simply the subjunctive form of گوش دادن.

Because the verb گوش دادن normally takes به before what you listen to.

So:

• به موسیقی گوش دادن = to listen to music
• به صدای آب گوش دادن = to listen to the sound of water

This is just how the verb works in Persian.

A very useful pattern to memorize is:

• به + noun + گوش دادن

Examples:

• به رادیو گوش می‌دهم
• به حرف معلم گوش کن
• به صدای پرنده‌ها گوش می‌دادم

So the به here is required by the verb.

This is the ezafe construction, one of the most important features of Persian grammar.

• صدا = sound
• آب = water
• صدای آب = the sound of water

The -e / -ye sound linking two nouns is called ezafe. In writing, when the first word ends in ا or و, Persian often shows this with ی:

• صدا → صدای
• pronounced roughly sedâ-ye âb

Other examples:

• خانه‌ی دوست = the friend’s house
• رنگِ آسمان = the color of the sky
• بوی گل = the smell of the flower

So صدای آب is just sound-of water.

کنار means beside, next to, or by.

So:

• کنار دریا = by the sea / beside the sea

It tells you the location of the action:

• کنار دریا بنشینم = sit by the sea

Other examples:

• کنار پنجره = by the window
• کنار دوستم نشستم = I sat next to my friend
• خانه‌مان کنار پارک است = Our house is next to the park

So کنار is functioning like a preposition-like word of place.

Persian usually puts the verb at or near the end of the clause, so this sentence follows a very natural Persian pattern.

A rough structure is:

• بعضی وقت‌ها = sometimes
• فقط = just
• می‌خواهم = I want
• کنار دریا بنشینم = to sit by the sea
• و = and
• به صدای آب گوش بدهم = to listen to the sound of water

So Persian often builds up the information first and leaves the main action until later.

This is very common:

• من کتاب را در خانه می‌خوانم
• literally: I the book at home read

In your sentence, the two actions:

• کنار دریا بنشینم
• به صدای آب گوش بدهم

both come before their final verbs, which is normal for Persian.

Yes, فقط means only, just, or simply, depending on context.

In this sentence it gives the feeling of:

• I just want to...
• I only want to...

Its placement is fairly natural here:

• بعضی وقت‌ها فقط می‌خواهم...

But Persian adverbs can sometimes move around for nuance or emphasis.

For example:

• فقط بعضی وقت‌ها می‌خواهم... = Only sometimes I want...
• بعضی وقت‌ها می‌خواهم فقط کنار دریا بنشینم... = Sometimes I want only to sit by the sea...

These versions shift the emphasis a bit. So yes, فقط can move, but where it appears affects what sounds most prominent.

Yes. That is exactly how the sentence works.

The structure is:

می‌خواهم [کنار دریا بنشینم] و [به صدای آب گوش بدهم]

So the speaker wants to do two things:

1. sit by the sea
2. listen to the sound of water

Because both verbs depend on می‌خواهم, both appear in the subjunctive:

• بنشینم
• بدهم

This is very common in Persian:

• می‌خواهم بروم و استراحت کنم
• می‌خواهم کتاب بخوانم و چای بنوشم

So the و joins two desired actions under one می‌خواهم.

In careful pronunciation, it would be close to:

ba‘zi vaght-hâ faqat mikhâham kenâr-e daryâ benshinam o be sedâ-ye âb gush bedaham

In everyday speech, several parts may become more casual:

• می‌خواهم often sounds like می‌خوام
• و often sounds like o
• بدهم may sound closer to بدم
• بنشینم may sound a bit shorter and smoother in fast speech

A colloquial spoken version might sound like:

بعضی وقتا فقط می‌خوام کنار دریا بشینم و به صدای آب گوش بدم

Notice some spoken changes:

• وقت‌ها → وقتا
• می‌خواهم → می‌خوام
• بنشینم → بشینم
• بدهم → بدم

So the written sentence is standard, but the spoken language is often a little shorter and smoother.

It is basically neutral standard Persian.

Why?

• The grammar is standard.
• The vocabulary is ordinary and natural.
• The spelling is mostly standard, though می‌خواهم would be more formal in writing than میخواهم.

In actual conversation, many speakers would use a more colloquial version such as:

• بعضی وقتا فقط می‌خوام کنار دریا بشینم و به صدای آب گوش بدم

That spoken version is more informal and conversational.

So you can think of the original sentence as:

• good standard written Persian
• still natural and understandable
• slightly more careful than casual everyday speech
