Learn Hardcore Turkish: Belirteceğin eksik parçalar tedarik edilince teslimat tamamlanacak. - Once the missing parts you specify are procured, delivery will be completed.

belirteceğin is the future participle of belirtmek, meaning that you will specify. It is built by:
• starting with the verb stem belirt-
• adding the future participle suffix -ecek → belirtecek
• adding the 2nd person singular suffix -(i)n → belirteceğin
In Turkish, participles like this go before the noun they describe.

Why does belirteceğin come before eksik parçalar instead of after it?

Turkish forms relative clauses as participles that precede the noun. So belirteceğin (the clause) appears directly before eksik parçalar (the noun), yielding belirteceğin eksik parçalar—equivalent to the missing parts that you will specify in English.

What does the suffix -ince do in tedarik edilince?

The suffix -ince creates an adverbial clause meaning when, once or as soon as. In tedarik edilince it gives when they are procured, linking this dependent clause to the main clause.

Why is tedarik edilince in the passive voice and how is it formed?

The active verb tedarik etmek means to procure. To make it passive, Turkish adds the passive marker -il (from -in) to the root and then -ince:

tedarik + et → tedarik et
- passive -il → tedarik edil
- adverbial -ince → tedarik edilince (when they are procured)

Who or what is the subject in tedarik edilince and teslimat tamamlanacak, and why are they unmarked?

In a passive sentence the logical object becomes the grammatical subject and appears unmarked (nominative):
• In tedarik edilince, eksik parçalar is the subject → when the missing parts are procured
• In teslimat tamamlanacak, teslimat is the subject → the delivery will be completed
Neither carries a case ending because Turkish marks passive subjects with the bare form.

What tense and voice is tamamlanacak, and how do you form it?

tamamlanacak is the passive future of tamamlamak (to complete):
• Stem tamamla-
• Passive suffix -n → tamamlan
• Future suffix -acak → tamamlanacak
It means will be completed.

Can you substitute tedarik edilince with sağlanınca, and does it alter the meaning?

Yes. sağlanınca comes from sağlanmak (to be provided):
Belirteceğin eksik parçalar sağlanınca teslimat tamamlanacak
The overall meaning stays the same. sağlamak is a general verb for providing, while tedarik etmek often implies more formal procurement or sourcing, but the sentence still means Delivery will be completed once the missing parts that you specify are provided.
