Licensing
SYNTAX: it has been proposed that well-formedness conditions on syntactic 
structure (esp. the principle of 
 
Full Interpretation) may be viewed 
as licensing conditions: the presence of an element in a structure is permitted if 
the element is licensed in any of a small number of ways. E.g. an argument in a 
structure is licensed if its chain contains a visible 
 
theta-position. Similarly, a VP is 
licensed if it functions as a predicate (hence the obligatoriness of sentential 
subjects stipulated in the  EPP).
