Andative and venitive

In linguistics, andative and venitive (abbreviated AND and VEN) are a type of verbal deixis, verb forms which indicate 'going' or 'coming' motion in reference to a particular location or person, respectively. Other terms sometimes seen are itive and ventive, or translocative and cislocative. They generally derive historically from the verbs go and come being reduced to auxiliary verbs or verbal affixes, and may in turn be grammaticalized to aspectual morphemes. Many languages of California, West Africa (such as Akan), the Caucasus-Mideast-North Africa (Akkadian, Sumerian), and Oceania have such verb forms.
