Looking under the hood

Exercise

Go to the Online Grammar and do the following:

  • Type "snores" into the Sentence textbox and press the "Parse" button or RETURN on your keyboard.
  • Click once on the top node of the tree.
  • Inspect the result and try to understand as much as possible.
  • Now click on the boxed "0" after AGR.

  • Inspect the result and try to understand as much as possible.
  • Finally, click on the boxed number below the NP in the SPR list.

  • Again, inspect the result and try to understand as much as possible.
  • Click on the new boxed "0" after the AGR that appears.

  • Now there are two boxed "0"s on the screen. What seems to be their function?

Exercise

Go to the Online Grammar and do the following:

  • Parse the sentence Lilly dances".
  • Open the S node and the V node. Don't open any numbered boxes for now.
  • Compare the two feature structures.
  • For every feature (= attribute), compare the values of mother and daughter.
  • Now open the N node, leaving its numbered boxes alone again.
  • Compare the three feature structures. What relationships do you detect? Do the self-test exercises below.

(1) The part of speech features of the mother are also the part of speech features of

the verb.


(2) The verb is looking for ______ complements.

Check your answer

A. The verb is complement-empty and selects one NP-specifier.
B. The NP acts as the verb's specifier.
C. As the verb's specifier requirement has now been satisfied, its mother S has an empty SPR list (as well as an empty COMPS list).


Head-Specifier Phrases

We can combine all the observations above into a Phrase Structure Rule. In short form, the rule can be formulated as follows:

(1) XP -> Specifier X

We call this kind of phrase a head-specifier phrase.

Instead of formulating the full-fledged PS rule, we look directly at the local tree that the rule licenses.

A head-specifier phrase can be formed by combining a sign [= the head daughter] with a second sign [= the non-head daughter] whose syntactic category can be unified with the syntactic category on the word’s spr list:
