Learn Turkish: Tembellik yapacağına ve sosyal medyada gezineceğine yaratıcı bir proje üstlen. - Instead of being lazy and browsing on social media, take on a creative project.

This uses the structure you are currently learning! It combines the future tense suffix -acak, the 2nd person singular possessive suffix -ın (your), and the dative case -a (to). While it literally translates to 'to your future doing', this specific formula -(y)AcAğInA is the standard Turkish way to express 'instead of doing' an action.

Why does the k in the future suffix change to ğ in yapacağına and gezineceğine?

This is a standard consonant mutation. When the future suffix -acak or -ecek is followed by a suffix starting with a vowel—in this case, the possessive suffix -ın or -in—the final hard k softens to a ğ (soft g). Thus, yapacak-ın-a smoothly becomes yapacağına.

Why use gezin instead of just gez for browsing social media?

While gezmek generally means to travel, tour, or walk around, the related verb gezinmek implies wandering around casually or aimlessly. In modern digital contexts, gezinmek is the perfect word for casually scrolling or browsing the internet without a strict destination.

Since ve connects two actions, do both verbs need the ending?
