Questions & Answers about Kim gelirse gelsin, veznedeki memur sıra numarasına göre çağırıyor.

What does kim gelirse gelsin mean?

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.

Why is the verb repeated in gelirse gelsin?

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.

What is the grammar of gelirse?

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.
