Мне нравится вид на море из окна.

Because нравиться does not work like English to like. Russian structures it more like to be pleasing to.

So:

• мне = to me in the dative case
• нравится = is pleasing / appeals
• вид на море из окна = the thing that is pleasing

So the sentence is literally something like To me is pleasing the view of the sea from the window.

That is why я нравится would be wrong here.

The verb agrees with the thing being liked, not with the person who likes it.

Here, the subject is вид which is singular, so you use singular нравится.

Compare:

• Мне нравится вид. = I like the view.
• Мне нравятся виды. = I like the views.

Нравлюсь means I am pleasing / liked, so it would be used in a completely different structure, for example Я тебе нравлюсь = You like me.

The subject is вид.

That can feel strange to an English speaker, because in English the subject would usually be I in I like.... But in Russian with нравиться, the thing that causes the feeling is the grammatical subject.

So in this sentence:

• мне = indirect object / experiencer
• вид = subject
• нравится agrees with вид

Вид на море is a very common Russian pattern meaning a view of/onto the sea, especially from a place such as a room, balcony, or window.

The key pattern is:

вид на + accusative

Examples:

• вид на море = sea view / view of the sea
• вид на город = view of the city
• вид на парк = view of the park

So на here does not mean simple physical direction like onto in a basic movement sense. It is part of the set expression вид на ....

It is in the accusative case here, because the expression is вид на + accusative.

However, море is a neuter inanimate noun, and for many neuter inanimate nouns, the nominative and accusative singular forms are identical.

So:

• nominative: море
• accusative: море

The case does change grammatically, but the form happens to look the same.

Окна is genitive singular of окно.

That is because the preposition из requires the genitive case.

So:

• окно = window
• из окна = from the window / out of the window

This phrase tells you the viewpoint: the sea view as seen from the window.

It describes the viewpoint of the view, not the sea itself.

So the meaning is:

the view of the sea as seen from the window

not

the sea coming out of the window

In real usage, this is understood naturally from context. English works similarly in phrases like the view of the sea from the window.

You could, but it is not the best choice if you mean a sea view from a place.

There is an important nuance:

• вид на море = a view onto the sea, especially from a room, house, window, hotel, etc.
• вид моря = the appearance/view/image of the sea itself

For real-estate or location-type descriptions, вид на море is the normal and idiomatic expression.

Yes, but the tone is different.

• Мне нравится вид на море из окна. = I like the sea view from the window.
• Я люблю вид на море из окна. = I love the sea view from the window / I really like it.

Люблю is usually stronger and more personal. Мне нравится is often the more neutral and natural way to say that something appeals to you.

No, Russian word order is flexible, but changing it changes emphasis.

The original sentence Мне нравится вид на море из окна is natural and neutral.

Other possible orders:

• Вид на море из окна мне нравится. = The sea view from the window is what I like.
• Из окна мне нравится вид на море. = From the window, I like the sea view.

All of these are possible, but the original order is a good standard version for learners.

Russian has no articles, so there is no direct equivalent of a or the.

Also, Russian often leaves possession unstated if it is clear from context. So из окна could mean:

• from the window
• from a window
• from my/the window

If you specifically want to say from my window, you would say из моего окна.

Because вид means view in the sense of what you can see from a place.

Взгляд means glance, look, or gaze. It refers to the act of looking, or someone’s look/expression, not a scenic view.

So:

• вид на море = sea view
• взгляд на море = a look at the sea

Those are different ideas.

A very literal breakdown is:

• Мне = to me
• нравится = is pleasing / appeals
• вид = the view
• на море = onto the sea / of the sea
• из окна = from the window

So literally:

To me is pleasing the view onto the sea from the window.

That literal structure helps explain why the grammar looks different from English.
