Consider the structure (4): [β...γ...α...γ...], where (i) α = X°; (ii) where φ is a maximal projection, if φ dominates γ then φ dominates α; (iii) α is an immediate constituent of β [...]. Then we define "government" as in (5): (5) α "governs" γ in (4).

(9) Consider the structure (i): (i) [β...γ...α...γ...], where (a) α =X° or is coindexed with γ; (b) where φ is a maximal projection, if φ dominates γ then φ dominates α; (c) α c-commands γ. In this case, α "governs" γ.
