as дверь and пыль, also have a locative form that differs from the prepositional in that the stress shifts to the final syllable: "на двери́", na dverí ("on the door"), but "при две́ри", pri dvéri ("by the door"). These distinct feminine forms are sometimes referenced as "second locative" or "new locative", because they developed independently from the true locative case, which existed in Old Russian. With some words, such as дом, dom (house), the second locative form is used only in certain idiomatic expressions, while the prepositional is used elsewhere. For example, "на дому́", na domu ("at the house" or "at home") would be used to describe activity that is performed at home, while "на до́ме" ("on the house") would be used to specify the location of the roof.

The morpheme may exist in four different forms, depending on the preceding consonant and vowel. The first phoneme of the locative, "D", changes according to the previous consonant: it is "t" after voiceless consonants, but "d" elsewhere. The vowel changes depending on the phonetic characteristics of the previous vowel: it is "a" after a preceding back vowel, and "e" after a preceding front vowel, congruent with the vowel harmony of the language. This gives four different versions of the morpheme: -ta, as in "kitapta", "in the book". -te, as in "kentte", "in the city". -da, as in "odada", "in the room". -de, as in "evde", "in the house". Azerbaijani The locative case also exists in Azerbaijani. Similarly to Turkish, Azerbaijani employs a system of vowel harmony throughout the language. There are two simple Locative case endings: -da, as in "kitabda", "in the book". -də, as in "şəhərdə", "in the city". Kazakh The locative case also exists in Kazakh.
