| '''Dominance''' is the relation between two nodes in a tree structure. A node "dominates" another node if it is above it in the tree (it is a parent, grandparent, etc). In the UNL<sup>arium</sup> framework, dominance is used to represent the structure of [[Syntax|maximal projections]] and, therefore, to state the degree of adjacency (i.e., the order) of constituents in relation to the head. Dominance is represented in the dictionary, in case of compound words that do not follow general dominance rules, or in the grammar, otherwise. Dominance is not represented in UNL.

| In the UNL<sup>arium</sup> framework, syntactic relations are described in terms of a general tree structure: the [[Syntax|X-bar]], depicted below.

| / \
| |
| spec XB
| |
| / \
| |
| XB adjt
| |
| / \
| |
| X comp
| |
| | |
| </pre>
| |
| | |
| In the X-bar structure, the node '''XP''' dominates all other nodes; the '''higher XB''' dominates the nodes '''adjt''', '''lower XB''', '''comp''' and '''X''' (head); the '''lower XB''' dominates the nodes '''comp''' and '''X'''; and the nodes '''spec''', '''adjt''', '''comp''' and '''X''' do not dominate any node.
