"Can"

(abil/ebil)

In Turkish, we express "can" using the suffix "abil/ebil". We attach the appropriate one to the verb root based on its last vowel. "abil/ebil" can be used with any tense but is usually used with present simple tense.

Positive

We begin with the verb root. We attach one of "abil/ebil" depending on the root's last vowel. If the letter at the end of the verb root is a vowel, we also first attach a "y" to prevent having two vowels side by side. Thereafter we add the tense suffix followed by the personal suffix.
