| − | '''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.

| − | In the X-bar structure above, 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.

| − | The structure above may have, however, several different configurations: it may have more than one complement (as in ditransitive constructions such as "I gave John the keys"), more than one adjunct ("He worked in the office from 6:00 AM to 6:00 PM during the last year"), complement-adjunct inversions, such as in "bring home the bacon". These modifications affect mainly the structure of the intermediary projection XB, which may indeed assume several different values, as indicated below:
