Genitive construction

In grammar, a genitive construction or genitival construction is a type of grammatical construction used to express a relation between two nouns such as the possession of one by another (e.g. "John's jacket"), or some other type of connection (e.g. "John's father" or "the father of John"). A genitive construction involves two nouns, the head (or modified noun) and the dependent (or modifier noun). In dependent-marking languages, a dependent genitive noun modifies the head by expressing some property of it. For example, in the construction "John's jacket", "jacket" is the head and "John's" is the modifier, expressing a property of the jacket (it is owned by John). The analogous relationship in head-marking languages is pertensive.
