		<summary type="html">&lt;p&gt;from Utrecht Lexicon of Linguistics&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;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. &lt;br /&gt;
&lt;br /&gt;
===Examples===&lt;br /&gt;
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.&lt;br /&gt;
&lt;br /&gt;
  (i)	 ... [&amp;lt;sub&amp;gt;A&amp;lt;/sub&amp;gt; ... [&amp;lt;sub&amp;gt;A&amp;lt;/sub&amp;gt; ... &lt;br /&gt;
  (ii) a ''I won't forget [&amp;lt;sub&amp;gt;NP&amp;lt;/sub&amp;gt; my trip to [&amp;lt;sub&amp;gt;NP&amp;lt;/sub&amp;gt; Africa ]].'' &lt;br /&gt;
       b ''*Africa, I won't forget my trip to''&lt;br /&gt;
       c ''my trip to Africa, I won't forget''&lt;br /&gt;
&lt;br /&gt;
===Comment===&lt;br /&gt;
More recently, the A-over-A principle has been reduced to principles such as the [[ECP]]. &lt;br /&gt;
