When a suffix starting with a vowel is added to some certain letters, these letters must change into a different letter to keep the pronounciation smooth.
These letters are:
Examples
For these examples we will use the '-(i)m' (my....) suffix.
The '-(i//u/ü)' is only used if the last letter is a consonant, otherwise just 'm' is added.
bed - yatak
my bed - yatağım
dolap - cupbard
my cupbard - dolabım
tıkaç - plug
tıkacım - my plug
köpek - dog
köpeğim - my dog
kurt - wolf
kurdum - my wolf
If the last letter in a word is either k/p/ç/f/t/h/b/ş, when a suffix beginning with 'd' is added, the first letter of the suffix changes from 'd' to 't'. This occurs in suffixes such as '-den/-dan' (from) and '-de/-da' (in/at/on).
