Practical Grammar 8

So far, the arguments of verbs have all been determiner phrases (= DPs) like names, pronouns, or Det-N configurations. But verbs can also take complements of other parts of speech. This week, we will encounter two new cases: complements which are a. prepositional phrases and b. subordinate clauses.

Prepositional Phrases

Presently, xlfg cannot handle complex annotations like that of the PP. Therefore, we will simplify the rule as follows:

2. VP → V          PP
       ↑=↓     (↑OBL) = ↓ 

This means that all PPs that combine with verbs bear the grammatical function OBL(IQUE).

(2) translates into xlfg as follows:

3. VP → V PP
2. {
3. ↑=↓1;
4. (↑OBL) = ↓2;
5. }

Add the following rule for PPs:

6.  PP → P DP
7.  {
8.  ↑=↓1;
9.  (↑OBJ) =↓2;
10. }

Exercise 7.1

1. Open Grammar-7.1
2. Add the two rules above to your grammar.
3. Also add a correctly annotated rule VP -> V DP PP.
2. Make sure that in all your VP rules that have a PP on the right the annotation on the PP is: (↑OBL) = ↓n.
3. Add the prepositions to on on to your lexicon as follows:

to P
[PRED: 'to<OBJ>',
 PCASE: OBL_REC]

on P
[PRED: 'on<OBJ>',
 PCASE: OBL_LOC]

4. Add the following test items:

a. Oscar donated clothes to charity
b. Robin put food on the table

5. Parse.

Exercise 7.2

1. Add the following test items:

a. *Oscar donated clothes on charity
b. *Robin put food to the table

2. Parse!
3. The grammar does not return the intended result. What is the problem?
4. The problem is easy to fix with the same technique that we used to enforce subject-verb agreement.
5. Do so and parse!

Complement Clauses

Exercise 8.1 (based on section 5.1 of the textbook)

• Go to https://147.210.117.56.

• Add the words in the following sentences:

(1) Fred thinks that Lilly disappeared
(2) Fred enquires whether Lilly disappeared

Implement the following:

1. that and whether belong to the part of speech C (= complementizer).
2. Complementizers head CPs.
3. CPs take two daughers: a C and an IP. The two daughters are co-heads of the CP.
4. You need to add a new VP rule which allows a VP to consist of a V and a CP. The CP bears the GF COMP.

• Make any further changes that are necessary to obtain the f-structure (10) on p. 101 for (1), with one exception: your grammar will not contain the information [CLTYPE DECL] in the main f-structure! For sentence (2), you should obtain an f-structure which is identical to that of sentence (1), with the exception that the CLTYPE of the COMP in (2) should be INTER.

Check what your grammar predicts for the following examples:

(3) *Fred thinks whether Lilly disappeared
(4) *Fred enquires that Lilly disappeared

If your grammar licenses these examples, then add information to it that makes it impossible to derive a well formed f-structure for them.

Hint: think about the function of each of the complementizers!

Subject Clauses

That- and whether-clauses can also act as subjects:

1. That Lilly disappeared sucks
2. Whether Lilly disappeared is unknown

Of course, the complementizers are still bound to their clause types:

3. *Whether Lilly disappeared sucks

Exercise 8.2

• Go to https://xlfg.labri.fr/.
• Add the sentences above to your test items.
• Change the grammar so that it makes the correct predictions for all test items.

Your grammar should yield the following Argument Structure for sentence (1):

Your grammar should yield the following Argument Structure for sentence (2):

Notes:

a. treat is as a verb which combines with a COMP and an OBJ.
b. treat unknown as an adjective.
