Learn Hardcore Turkish: Nöral ağları inceleyen araştırmacılar toplantıya davet edildi. - Researchers studying neural networks were invited to the meeting.

The suffix -en is an active participle marker in Turkish. It turns the verb incelemek (“to examine/study”) into an adjective meaning “who examines/studies.” So inceleyen araştırmacılar literally means “researchers who study/examine.”

Why is there a y in inceleyen?

When a verb stem ends in a vowel (here incele- ends in e) and you attach a vowel‐starting suffix like -en, you insert a buffer consonant y to avoid two vowels in a row. Hence incele- + y + en → inceleyen.

Why is ağları in the accusative case with -ları?

Nöral ağları is the direct object of inceleyen and refers to a specific set of networks (“neural networks”). Turkish marks specific direct objects with the accusative suffix -ı/-i/-u/-ü. The noun ağ (“network”) is plural, so you add -lar for plural + -ı for accusative → ağ-lar-ı.

Why is toplantıya in the dative case with -a?

In Turkish, you invite someone to an event, and the dative case (-e/-a) expresses that “to” meaning. So toplantı (“meeting”) + -ya → toplantıya (“to the meeting”).

What does davet edildi tell us grammatically?

Davet edildi is the passive form of davet etmek (“to invite”). It’s built from davet (“invitation”) + the passive marker -il + the past tense -di, giving edil-di, so davet edildi = “(they) were invited.”

Why is there no third‐person plural ending on edildi even though araştırmacılar is plural?

In Turkish passive constructions, the third‐person is usually unmarked. The form edildi covers both singular and plural subjects. If you need to, you can explicitly mark the plural with -ler (→ davet edildiler), but the standard passive doesn’t.

How can I specify who did the inviting in this passive sentence?

Add an agent with tarafından (“by”):
Nöral ağları inceleyen araştırmacılar bilim kurulu tarafından toplantıya davet edildi.
= “The researchers who study neural networks were invited to the meeting by the scientific committee.”

Can I turn the sentence into active voice?

Yes—give an explicit subject (the inviter) and use S-O-V:
Bilim kurulu nöral ağları inceleyen araştırmacıları toplantıya davet etti.
= “The scientific committee invited the researchers who study neural networks to the meeting.”

How is the noun phrase Nöral ağları inceleyen araştırmacılar structured?

Breakdown of suffixes/morphemes:
• Nöral = adjective “neural”
• ağ-lar-ı = ağ (“network”) + -lar (plural) + -ı (accusative)
• incele-yen = incele (“study/examine”) + buffer y + participle -en
• araştırma-cı-lar = araştırma (“research”) + agentive -cı (“one who…”) + -lar (plural)
All together: “the researchers who examine neural networks.”
