Kim gelirse gelsin, veznedeki memur sıra numarasına göre çağırıyor.

It means whoever comes, no matter who comes, or regardless of who comes.

This whole expression tells you that the identity of the person does not affect what happens next. In this sentence, it means that the clerk will still call people according to their queue number, not according to who they are.

This is a very common Turkish pattern used to express it doesn’t matter who/what/how/etc.

So:

• kim gelirse gelsin = whoever comes / no matter who comes
• ne derse desin = whatever he/she says
• nereye giderse gitsin = wherever he/she goes

The repetition is not accidental. It creates a concessive meaning: even if X happens, the result is still the same.

Gelirse can be broken down as:

• gel- = come
• -ir- = aorist marker here
• -se = conditional if

So literally, gelirse is something like if he/she comes.

In this sentence, though, it is part of the fixed pattern kim gelirse gelsin, so you should understand the whole chunk together rather than translating each piece too mechanically.

Gelsin is the 3rd person imperative/optative form of gelmek.

On its own, it can mean something like:

• let him/her come
• he/she should come

But in kim gelirse gelsin, it is not really functioning as a separate command. It is part of the idiomatic repeated-verb structure that gives the meaning whoever comes.

It means the clerk at the cashier’s desk / the clerk at the counter.

Breakdown:

• vezne = cashier’s desk, payment window, teller’s desk
• -deki = the one at/in/on

So:

• veznedeki memur = the clerk who is at the cashier’s desk

This -deki ending is very useful in Turkish for making location-based descriptions.

Examples:

• masadaki kitap = the book on the table
• odadaki insanlar = the people in the room
• veznedeki memur = the clerk at the cashier window

It means according to the queue number or based on the ticket number.

Breakdown:

• sıra = queue, line, turn
• numara = number
• sıra numarası = queue number / ticket number
• -na göre = according to

So the whole phrase means that the clerk is calling people in the order of their assigned numbers.

Because göre requires the dative form, and sıra numarası is a possessed noun phrase.

Here is the structure:

• sıra numarası = its queue number / queue number
• sıra numarasına = to/according to the queue number

That -sı in numarası is the 3rd person possessive ending, and when the dative is added, you get -na.

So:

• numara → numaraya
• numarası → numarasına

This is normal Turkish grammar after possessed nouns.

Çağırıyor is the present continuous form, but in Turkish it is often also used for current procedures or what is happening in this situation.

So here it can mean something like:

• the clerk is calling people according to their queue number
• the clerk calls people according to their queue number

In English, we might use either the simple present or present progressive depending on context. In Turkish, -yor is very natural for describing what is currently going on in a place like a bank, office, or hospital.

If you said çağırır, that would sound more like a general rule or habitual fact.

Not with the same meaning.

• Kim gelirse gelsin = whoever comes / no matter who comes
• Kim gelirse ... by itself usually needs the rest of the sentence to relate directly to that person, such as Kim gelirse onunla konuşurum = Whoever comes, I talk to that person

So the second gelsin is important because it gives the sentence the it makes no difference who meaning.

Because Turkish often puts the condition, background, or contrast first, and the main result after it.

So the sentence is structured like this:

• Kim gelirse gelsin = no matter who comes
• veznedeki memur sıra numarasına göre çağırıyor = the clerk calls according to the queue number

Starting with the concessive clause highlights the contrast: people may vary, but the system stays the same.

No. Memur is grammatically and semantically gender-neutral.

It can refer to:

• a male clerk
• a female clerk
• an official/employee in a public or administrative setting

Turkish usually does not mark gender in nouns the way English sometimes does. Context tells you whether the person is male or female, if that even matters.
