Learn Turkish: Figüranları sokakta yürütebilirsin. - You can have the extras walk on the street.

This is the core rule for the causative voice! The original verb yürümek (to walk) is intransitive, meaning it does not take a direct object. When you make an intransitive verb causative, the person being made to do the action (the causee) becomes the new direct object and takes the accusative case.

Can you break down the suffixes in yürütebilirsin?

It starts with the root yürü (walk), followed by the causative suffix -t (make walk). Next is the ability suffix -ebil (can), then the aorist tense -ir to make it a general present tense statement, and finally the personal ending -sin (you). Altogether: yürü-t-ebil-ir-sin.

Why is it sokakta (on the street) instead of a directional ending like sokağa?

Even though walking involves movement, the extras are walking around within the location of the street itself, rather than traveling to the street as a destination. Because the action is contained entirely within that area, we use the locative case -ta.

Why does the plural suffix for figüran use the back vowel a (-lar) when the word has an ü?
