Sağ kapıdan gir.

Here, sağ means right as in direction, the opposite of left.

In sağ kapıdan gir, it describes kapı (door), so sağ kapı means the right door or the door on the right, depending on context.

A useful contrast:

• sağ = right
• sol = left

So you might also see:

• Sol kapıdan gir. = Enter through the left door.

Because Turkish adds the ending -dan / -den / -tan / -ten to show meanings like from, out of, or in some expressions through/by way of.

So:

• kapı = door
• kapıdan = from the door / through the door

With verbs of movement, Turkish often uses this construction where English uses through:

• Kapıdan gir. = Enter through the door.
• Pencereden bak. = Look through the window.

So even though -dan often gets introduced as from, in real Turkish it has a wider range of uses.

This is because the ablative ending changes shape according to vowel harmony and consonant voicing.

The ablative suffix has four common forms:

• -dan
• -den
• -tan
• -ten

In kapıdan:

• the last vowel in kapı is ı, which is a back vowel, so we use a rather than e
• kapı ends in a vowel, so we use d rather than t

That gives kapı + dan = kapıdan.

Compare:

• evden = from the house
• ağaçtan = from the tree
• köprüden = from the bridge

Gir is the informal singular imperative of girmek (to enter / to go in).

It is what you say when telling one person directly to do something:

• Gir. = Enter.
• Otur. = Sit.
• Bak. = Look.

So Sağ kapıdan gir is a command addressed to you.

If you wanted to be more polite or speak to more than one person, you would say:

• Sağ kapıdan girin.

It is not said explicitly, because in Turkish the subject is often understood from the verb form, especially in commands.

In gir, the subject is implicitly you singular.

So Turkish does not need a separate word here like English does.

You could add sen for emphasis, but it is usually unnecessary:

• Sen sağ kapıdan gir.

This would sound more emphatic, like you go in through the right door.

Turkish usually places the verb at the end of the sentence.

So the structure here is roughly:

• sağ kapıdan = through the right door
• gir = enter

That means the sentence follows a common Turkish pattern: place/direction + verb

This is very normal in Turkish:

• Eve git. = Go home.
• Burada bekle. = Wait here.
• Kapıdan çık. = Go out through the door.

It can work, especially when you are choosing between a left and right door.

However, learners should know that Turkish often uses -daki for something like the one that is on/in/at a place.

So a more explicit version would be:

• Sağdaki kapıdan gir. = Enter through the door on the right.

The difference is roughly:

• sağ kapı = the right door
• sağdaki kapı = the door that is on the right

In many situations, sağdaki kapıdan gir sounds more specific and natural.

The ğ in Turkish is unusual for English speakers.

In sağ, the ğ is usually not pronounced like a hard g. Instead, it often lengthens the vowel before it.

So sağ sounds approximately like:

• saa

Not exactly like English sag.

This is important because many learners try to pronounce ğ as a normal g, but that is usually wrong in Turkish.

In this sentence, the natural meaning is through the right door.

Even though -dan often means from, with certain movement verbs it can describe the route or opening used.

So:

• kapıdan gir = enter through the door
• kapıdan çık = go out through the door

A literal word-for-word gloss can be misleading here. It is better to learn kapıdan girmek as a very common Turkish pattern.

Turkish does not have articles like English the and a/an.

So kapı can mean:

• door
• a door
• the door

The exact meaning depends on context.

In this sentence, context tells you which door is meant:

• sağ kapı already identifies it, so English naturally uses the right door

This is very common in Turkish, and learners get used to understanding definiteness from context rather than from articles.

Yes. That is the polite or plural version.

Compare:

• Sağ kapıdan gir. = informal, to one person
• Sağ kapıdan girin. = polite to one person, or to several people

English does not always show this difference clearly, but Turkish does, so choosing between gir and girin matters socially.
