A grammatical case is a category of nouns and noun modifiers that corresponds to one or more potential grammatical functions for a nominal group in a wording. In various languages, nominal groups consisting of a noun and its modifiers belong to one of a few such categories. For instance, in English, one says I see them and they see me: the nominative pronouns I/they represent the perceiver and the accusative pronouns me/them represent the phenomenon perceived. Here, nominative and accusative are cases, that is, categories of pronouns corresponding to the functions they have in representation.

In linguistic typology, ergative–absolutive alignment is a type of morphosyntactic alignment in which the single argument ("subject") of an intransitive verb behaves like the object of a transitive verb, and differently from the agent ("subject") of a transitive verb. Examples include Basque, Georgian, Mayan, Tibetan, and certain Indo-European languages. It has also been attributed to the Semitic modern Aramaic languages. Ergative languages are classified into 2 groups: those that are morphologically ergative but syntactically behave as accusative and those that—on top of being ergative morphologically—also show ergativity in syntax. No language has been recorded in which both the morphological and syntactical ergative are present. Languages that belong to the former group are more numerous than those to the latter. Dyirbal is said to be the only representative of syntactic ergativity, yet it displays accusative alignment with certain pronouns.
Lezgian, also called Lezgi or Lezgin, is a Northeast Caucasian language.

Khwarshi is a Northeast Caucasian language spoken in the Tsumadinsky-, Kizilyurtovsky- and Khasavyurtovsky districts of Dagestan by the Khwarshi people. The exact number of speakers is not known, but the linguist Zaira Khalilova, who has carried out fieldwork in the period from 2005 to 2009, gives the figure 8,500. Other sources give much lower figures, such as Ethnologue with the figure 1,870 and the latest population census of Russia with the figure 1,872. The low figures are because many Khwarshi have registered themselves as being Avar speakers, because Avar is their literary language.
