Learn Turkish: Ekip her detayı patrona iletsin. - Let the team forward every detail to the boss.

The suffix -sin is the 3rd person singular imperative ending, meaning "let him/her/it" do something. Even though a team (ekip) has many people, it is grammatically a singular noun in Turkish, so we use -sin instead of the plural -sinler. The root verb is iletmek (to forward).

Is the 'y' in detayı a buffer letter?

No, the root word is detay (detail), which already ends in the consonant 'y'. The only suffix added here is the accusative case vowel -ı, marking it as the direct object of the verb. We use the accusative case here because the word her (every) makes the object specific.

Why is it patrona instead of just patron?

The verb iletmek (to forward) needs a destination, which is shown in Turkish using the dative case (meaning "to" or "towards"). Adding the vowel -a to patron turns it into patrona (to the boss).

Could we say patrona her detayı instead of her detayı patrona?
