Learn Turkish: Benim fuayede tanıştırdığım misafirler kartvizitlerini paylaştı. - The guests that I introduced in the foyer shared their business cards.

The root is tanı- (to know). First, we add the reciprocal suffix -ş to get tanışmak (to know each other / to meet). Next, we add the causative suffix -tır to get tanıştırmak (to cause to meet each other, which means "to introduce"). Finally, the object participle -dık and possessive -ım turn it into the relative clause "that I introduced".

Why is the pronoun Benim in the genitive case ("my") instead of just Ben ("I")?

In Turkish, relative clauses formed with the -dık suffix function grammatically like possessed nouns. The subject of the clause takes the genitive case (Benim), and the verb takes the corresponding possessive suffix (-ım in tanıştırdığım). Literally, the structure reads like "my foyer-introduced guests".

Can you break down the chain of suffixes on kartvizitlerini?

Sure! The root is kartvizit (business card). We add -ler for plural, followed by -i for the third-person possessive (together making "their business cards"). Because these cards are the specific direct object being shared, we must add the accusative case suffix -i at the end. The -n- is a mandatory buffer letter used whenever a case marker attaches to a third-person possessive suffix.

The subject (guests) is plural. Why doesn't the verb have a plural suffix ()?
