"The frog eats the apple."
Translation:Kurbağa elmayı yer.
What's the difference between "i" & "ı".
They are different letters with different pronunciations, because Turkish has more vowels than the standard five (a e i o u) of Latin -- it has eight (a ı e ö i ü o u), which come in pairs (rounded and unrounded).
Note that the capital version of i is İ and the capital version of ı is I in Turkish.
