Questions & Answers about Misafirler gelince, fotoğrafçı aile fotoğrafını çekecek.
Gelince is built from the verb stem gel- (to come) plus the suffix -ince. This form creates a time clause meaning when, once, or after someone comes.
So:
- gel- = come
- gelince = when/once (someone) comes
This is a very common Turkish pattern. English often uses a separate word like when, but Turkish often uses a suffix on the verb instead.
Because gelince is not a full main-clause verb here. It is a subordinate verb form, often called a converb or adverbial verb form. These forms usually do not take the full set of personal endings that ordinary tense forms do.
The subject is shown separately by misafirler (the guests), so misafirler gelince naturally means when the guests arrive.
