The Locative case (Bulunma Hali) indicates the location where something is or where an action takes place. It generally translates to "in," "on," or "at."

Suffixes:

The locative suffix follows A-Type vowel harmony and consonant assimilation (hardening):

• After vowels and voiced consonants: -da (if last vowel is a, ı, o, u) or -de (if last vowel is e, i, ö, ü).
• After voiceless consonants (f, s, t, k, ç, ş, h, p - "FıSTıKÇı ŞaHaP"): -ta (if last vowel is a, ı, o, u) or -te (if last vowel is e, i, ö, ü).

Examples:

• Evdeyim. (I am at home.) (ev + -de)
• Kitap masada. (The book is on the table.) (masa + -da)
• Okulda öğrenciler var. (There are students at school.) (okul + -da)
• Sokakta yürüyor. (He/She is walking in the street.) (sokak + -ta, k is voiceless)
