Can: -ebil

To say can (ability or permission), add -ebil after e, i, ö, ü or -abil after a, ı, o, u to the verb stem, then the aorist -ir and the person ending. After a vowel, insert y.

• gel → gelebilirim (I can come), kal → kalabilirsin (you can stay)
• uğra → uğrayabilir, yardım et → yardım edebilir (t becomes d)

In questions the particle comes after -ebilir, so it is always mi: Kalabilir miyim? (May I stay?), Konuşabilir misiniz? (Could you speak?). For an ability you have right now, -ebiliyor is also common: iyi yüzebiliyor (she can swim well).

In the past, -ebildi means managed to: Bilet alabildim (I managed to get a ticket). With ancak it means only managed to.
