gülebilmeyi

Now I understand that gül = smile 

                                 ebil= can 

but the rest I couldnt get it  explanation is needed

to be able to laugh - it is accusative

gül-ebil-me-y-i

gül: to laugh

ebil: be able to

me : to (infinitive)

y: buffer letter

i : accusative

me = infinitive marking (makes it a noun)

y = buffer

i = accusative ending

To understand it completely you should look at it in a sentence, especially in connection with the predicate verb.

Sorry, gokuyum. You said it.

Yours is appreciated too.
