Nominal suffixes

When preceding vowel-ending suffixes; the final consonants -ç, -k, -p, and -t are voiced to -c, -ğ, -b, and -d, but there are a few nouns which do not follow this voicing rule. Some nominals like oğul elide their last vowel and change their stems before vowel-starting suffixes, like this: oğl- (This still follows the vowel harmony from the elided last vowel.) A few nouns like rol and hâl (loanwords) follow irregular front vowel harmony instead of last vowel. Some nominals like hal (also loanwords) may double their final consonant. This depends on their etymology.

Su and ne are the only nominals taking -y- before all vowel-starting suffixes (suyun, suyu; not *sunun, *susu).

Case suffixes

Accusative: -(y)⁴
- -i, -ı, -ü, -u / -yi, -yı, -yü, -yu
Dative: -(y)²
- -e, -a / -ye, -ya
Locative: -t/d²
- -te, -ta / -de, -da
Ablative: -t/d²n
- -ten, -tan / -den, -dan
Genitive: -(n)⁴n
- -in, -ın, -ün, -un / -nin, -nın, -nün, -nun
Instrumental: -(y)l²†
- -le, -la / -yle, -yla

† Some have included the instrumental case, but traditionally is not considered a grammatical case due to its status as an enclitic. In templates like {{tr-infl-noun-c}}, the instrumental is not included.

Tenses

In verbs demek and yemek, stems changed from -e- to -i- before imperfective, future, optative, and imperative (diyor, diyecek). In verbs with vowel-ending stems, the last vowel is deleted in imperfective and replaced with vowel harmony from stem's second-to-last vowel. In aorist, the change from (⁴)r to (²)r is somewhat unpredictable, see also the usage notes at -er.
