In Turkish, pronunciation is designed to flow smoothly. When a word ends in a hard consonant and you add a suffix starting with a vowel (like the dative -a or -e), that hard consonant usually "softens".
This is known as consonant mutation. The hard consonants k, t, p, and ç change to ğ, d, b, and c. A helpful way to remember these four letters is the word "ketçap" (ketchup).
- k becomes ğ
- t becomes d
- p becomes b
- ç becomes c
The "k" to "ğ" Mutation
When adding the dative suffix to words ending in k, the k turns into a soft ğ. For example, sözlük (dictionary) becomes sözlüğe, and durak (bus stop) becomes durağa.
The "t" to "d" Mutation
Words ending in t change to d before a vowel. Watch how kağıt (paper) becomes kağıda, and yurt (dormitory) becomes yurda.
The "ç" and "p" Mutations
Similarly, ç softens to c, and p softens to b. See how ilaç (medicine) takes the dative suffix to become ilaca, and hesap (account) becomes hesaba.
More Verbs That Take the Dative Case
In the previous lesson, you saw that physical destinations and verbs like bakmak (to look) take the dative case. Turkish also uses the dative case for certain abstract verbs.
In English, you believe or trust someone directly. In Turkish, you believe to someone and trust to someone. Let's see these in action, applying the consonant mutation rules to the words çocuk (child) and köpek (dog).
