illative case

The paradigm usually consists of the inessive, elative and illative cases.

The illative case, denoting direction of movement, occurs rarely in modern standard Lithuanian, although used in the common spoken language, especially in certain dialects.

The illative case in Lithuanian has its own endings, that are different for each declension paradigm, although quite regular, compared with some other Lithuanian cases.

For example, an inessive case, an illative case, an adessive case and allative case are borrowed from Finnic.

The illative case also changes form with a consonant stem, where the ending -hen is assibilated to -seen, as -hen is the genitive.

It is done in loanwords and abbreviations; e.g., USA:han for the illative case of "USA".

The illative case was used extensively in older Lithuanian; the first Lithuanian grammar book by Daniel Klein, that mentions both illative and į+accusative, calls the usage of the illative "more elegant".

Another etymology is the vocalization of a fricative such as the voiced velar fricative or voiced palatal fricative, e.g. Finnish illative case, or even an approximant, as the English 'r'.

The original locative case had been replaced by four so-called postpositive cases, the inessive case, illative case, adessive case and allative case, which correspond to the prepositions "in", "into", "at" and "towards", respectively.
