Constituency

Constituency is the feature of being a constituent and how words can work together to form a constituent (or phrase). Constituents are often moved as units, and the constituent can be the domain of agreement. Some languages allow discontinuous phrases in which words belonging to the same constituent are not immediately adjacent but are broken up by other constituents. Constituents may be recursive, as they may consist of other constituents, potentially of the same type.
