The first five rules are phrase-structure rules (PS rules); rule (6) is a transformational rule (T rule). The transformational rules depend upon the prior application of the phrase-structure rules and have the effect of converting, or transforming, one phrase marker into another. The phrase structure rules you are using are, so called, "context free". These have the general form of (i), where X is the name of the phrase and Y Z W defines its structure. The arrow is read as 'is rewritten as,' 'has as its constituents,' 'consists of,' or 'is expanded as.' ); or. So, for example, an English sentence typically consists of a noun phrase followed by a verb phrase (as in My sister bought a car), and we, therefore, write a phrase-structure rule as follows: This says that a sentence may consist of a noun phrase followed by a verb phrase. 0000038041 00000 n Phrase structure trees start with the highest constituent then analyzes it into phrases like NP, VP, etc., as I'm sure we all know.
