Adjacency is the relation between two branches in a tree structure. In the UNLarium framework, adjacency is used to represent the structure of maximal projections and, therefore, to state the distance of constituents in relation to the head.

In the UNLarium framework, syntactic relations are described in terms of a general tree structure: the X-bar, depicted below.

In structure above, the distance between the nodes X and comp is said to be lower than the distance between X and adjt, which is said to be lower than the distance between spec and X. This distance can be easily measured in terms of projections between the nodes: there's only one projection (lower XB) between X and comp; there are two projections (lower XB and higher XB) between X and adjt; and there are three projections between X and spec.
The number of intermediate projections define the values of the adjacency in the UNLarium framework, which are the following:
