Consonants often change at the end of words depending on whether it is followed by a vowel or a consonant. If they are followed by a vowel, they will generally change into voiced consonants. For example:
![](
This means: p → b t → d k → ğ ç → c
This rule in general does not affect single syllable words, but there are exceptions of course. You will even come across exceptions to vowel harmony in loanwords from Arabic, Farsi, and French. These must be learned as you encounter them. In the meantime, happy learning and kolay gelsin.
