The main application of the government relation concerns the assignment of case. Government is defined as follows:
A governs B if and only if
- A is a governor and
- A m-commands B and
- no barrier intervenes between A and B.
Governors are heads of the lexical categories (V, N, A, P) and tensed I (T). A m-commands B if A does not dominate B and B does not dominate A and the first maximal projection of A dominates B. The maximal projection of a head X is XP. This means that for example in a structure like the following, A m-commands B, but B does not m-command A:
In addition, barrier is defined as follows: A barrier is any node Z such that
- Z is a potential governor for B and
- Z c-commands B and
- Z does not c-command A
The government relation makes case assignment unambiguous. The tree diagram below illustrates how DPs are governed and assigned case by their governing heads:
Another important application of the government relation constrains the occurrence and identity of traces as the Empty Category Principle requires them to be properly governed.

Famous quotes containing the word government:
“If there was twenty ways of telling the truth and only one way of telling a lie, the Government would find it out. Its in the nature of governments to tell lies.”
—George Bernard Shaw (18561950)
“What happens in a strike happens not to one person alone.... It is a crisis with meaning and potency for all and prophetic of a future. The elements in crisis are the same, there is a fermentation that is identical. The elements are these: a body of men, women and children, hungry; an organization of feudal employers out to break the back of unionization; and the government Labor Board sent to negotiate between this hunger and this greed.”
—Meridel Le Sueur (b. 1900)
“You and I ... are convinced of the fact that if our Government in Washington and in a majority of the States should revert to the control of those who frankly put property ahead of human beings instead of working for human beings under a system of government which recognizes property, the nation as a whole would again be in a bad situation.”
—Franklin D. Roosevelt (18821945)
