A-over-A

SYNTAX: the A-over-A Principle says that if a rule ambiguously refers to A in a structure of the form of (i), the rule must apply to the higher, more inclusive, node A. EXAMPLE: this principle prevents extraction of the NP Africa out of the NP my trip to Africa in which it is included in (ii)b, but allows the more inclusive NP to be fronted in (ii)c.

(i)	 ... [A ... [A ... 
(ii) a	 I won't forget [NP my trip to [NP Africa ]] 
     b  *Africa, I won't forget my trip to
     c	 my trip to Africa, I won't forget
