Character Arc
The bow of change stretching from the character's starting behaviour, through costs, to their final choice. Its measure is behaviour: even with the lines deleted, the change should be visible.
Distinction: Arc and growth aren't the same thing: growth is the character getting better, an arc is only their CHANGING. Some arcs go downwards; some don't budge at all and change everyone around them.
Common mistake
Writing an adjective transformation ("coward → brave") — an arc is a choice, not a label.
Example — Saliha's Last Scene
In the film's first scene Saliha throws the dough her apprentice Nazlı rolled out into the bin at a single glance. In the last scene she stands in the doorway — she doesn't go in. Nazlı turns the dough; one corner stays thick. Saliha's hand goes to the apron tie. It stops.
The arc is right there between those two words: the hand GOES (the old behaviour is still there), but it STOPS (the new choice). Nazlı sees the mistake herself and corrects it; Saliha nods once, hangs the apron on the nail and, for the first time, looks at her own kitchen from where she's sitting.
Nowhere does it say "she trusted her now." Trust is staged as being able to watch a mistake and wait for it to be corrected.

How to build a character arc
- Write the starting behaviour, not the adjective. "Stubborn" is a label; "throwing the apprentice's dough into the bin at a single glance" is a behaviour, and it can be played in a scene.
- Find the time that behaviour used to work. A flaw is a shield: it once protected, today it exacts a cost.
- Build the ladder of cost. The character doesn't change; the bill for not changing grows. An arc moves forward by paying, not by being persuaded.
- Bring the same situation back in the finale. An arc is measured not by a new scene but by the difference in a repeat of the first one.
- Tie the decision to an action. The final choice should be a movement, not a sentence: the hand stopping, the apron being hung up, the place she sits changing.
Check
Delete every line from the scene. If the change is still visible, the arc was written; if it's only understood, it was narrated.
