Kapıdan geçer geçmez salona gir.

Geçer geçmez means as soon as (someone) passes or the moment (someone) passes.

Turkish often uses a repeated-verb pattern for this idea:

• geçer geçmez = as soon as one passes
• gelir gelmez = as soon as one comes
• duyar duymaz = as soon as one hears

So the repetition is not random. It is a fixed grammatical structure used to show that one action happens immediately after another.

It is formed by repeating the same verb in two parts:

• first part: aorist/general form
• second part: negative aorist form

So:

• geçmek → geçer geçmez
• gelmek → gelir gelmez
• çıkmak → çıkar çıkmaz

This structure means as soon as... or immediately after...

It is a very common pattern in Turkish, and learners should treat it as a standard time expression.

Kapıdan is kapı + dan, where -dan is the ablative ending.

The ablative often means:

• from
• out of
• through/from

In this sentence, kapıdan geçmek means to pass through the door or to go by the door/opening.

So kapıdan shows the point or route through which the action happens.

Because the verb girmek normally takes the dative case, which shows movement into a place.

• salona gir = enter the living room / go into the hall
• salonda = in the living room / in the hall
• salonu = the living room as a direct object, which would not fit with girmek

So:

• -a / -e = direction toward, into
• -da / -de = location in, at
• -ı / -i / -u / -ü = direct object

With girmek, Turkish uses the place in the dative:

• okula girmek = enter the school
• odaya girmek = enter the room
• salona girmek = enter the living room / hall

Gir is the second-person singular imperative of girmek.

It means:

• enter!
• go in!

It is a command directed to you (singular, informal).

Related forms:

• gir = enter! (informal singular)
• girin = enter! (plural or polite singular)

So this sentence is giving an instruction or command.

Because Turkish often drops subject pronouns when they are already clear from the verb form.

In gir, the command already tells you that the subject is you.

So the sentence means something like:

• (You,) as soon as you pass through the door, enter the living room.

Adding sen would usually be unnecessary unless you want emphasis.

They describe two different actions:

• geçmek = to pass, go through, cross
• girmek = to enter, go into

So the sentence has a sequence:

1. kapıdan geçmek = pass through the door
2. salona girmek = enter the living room / hall

In English, both might sometimes sound similar, but Turkish keeps the two actions separate.

Salon can mean different things depending on context, such as:

• living room
• hall
• lounge
• main room

In a home, salon often means living room. In a larger building, it could mean hall or main room.

So salona gir could be translated differently depending on the situation, but the grammar stays the same.

Turkish does not have articles exactly like English a and the.

So:

• kapıdan can mean from the door, through the door, or sometimes through a door
• salona can mean into the living room, into the hall, or into a hall

The exact meaning depends on context.

In many cases, English requires the or a, but Turkish does not need a separate word for that.

The given order is natural and clear:

• Kapıdan geçer geçmez salona gir.

This puts the time clause first:

• As soon as you pass through the door, enter the living room.

Turkish word order is flexible, so other arrangements are possible for emphasis, but this version is the most straightforward.

The important thing is that kapıdan geçer geçmez acts as the time expression, and salona gir is the main command.

Yes. Turkish has other ways to express time relations, but they are not always exactly the same in tone.

For example:

• Kapıdan geçince salona gir. = When/once you pass through the door, enter the living room.
• Kapıdan geçtikten sonra salona gir. = After passing through the door, enter the living room.

But geçer geçmez is stronger in the sense of immediately or the moment that. It emphasizes that the second action should happen right away.

Yes. Because gir is an imperative, the whole sentence sounds like an instruction, command, or direction.

Depending on context, it could be something like:

• giving directions in a building
• telling someone how to move through a house
• instructing someone where to go next

So it is not just describing actions; it is telling someone what to do.
