Questions & Answers about Genç mimar büyük bir park tasarlayabilir.
How do we get "can design" from tasarlayabilir?
Let's break it down! The verb stem is tasarla (to design). Because it ends in a vowel, we need the buffer letter y. Then we add the ability suffix abil (can), and finally the aorist tense suffix ir.
Why is the aorist tense (-ir) used here for "can"?
The ability suffix -(y)abil is almost always paired with the aorist tense when you want to express a general ability, skill, or possibility. It simply tells us the architect has the skills to do this.
Is it possible to use the present continuous tense here instead, like tasarlayabiliyor?
Yes, but it changes the meaning slightly. Using the aorist (tasarlayabilir) means "he can design" as a general fact. Using the continuous -iyor (tasarlayabiliyor) would emphasize that he is physically managing or able to design it right at this very moment. For a simple "can", we prefer the aorist!
Just as a refresher, why is it büyük bir park instead of bir büyük park?
This is a strict word order rule in Turkish! When you have an adjective describing a noun with bir (a/an), the order must be Adjective + bir + Noun. So, "a big park" literally translates to "big a park".
