Problem 1

Background

As discussed in the lecture notes, individual human languages often have quite regular patterns of word order, even though the particular patterns may vary from language to language. Here are two examples of generalizations we can make about English word order:

i) In English, the verb generally precedes the object, so that we say:

     instead of

     Note: (*) means that the sentence is ill-formed or ungrammatical (in the descriptive sense!) in the language in question.

ii) Furthermore, English has prepositions – that is, words like for, of and with precede the nouns they are associated with. This means that we say:

     instead of

Look at the following sentences from Hindi. In line 2 of each example, there is a word-for-word translation (or gloss). In line 3, the sentence is translated into its English equivalent. Compare the first and third lines of each example.

Question:

How is Hindi word order different from English word order? Talk specifically about the placement of verbs and words like with.


Problem 2

Background

Beyond the basic word order differences among languages, syntax is concerned with the fundamental idea that human language is hierarchically structured. In any given sentence, certain groups of words seem to be more closely related than others, and we can keep breaking down these groups of words into smaller and smaller units. The basic idea is that sentences are interpreted, layer by layer, in a way that depends on their structure.

One way to illustrate this point is by observing cases of structural ambiguity. Look at the following newspaper headline:

Why is this funny? Because in addition to the intended interpretation ('the farmer had an ax and the cow injured the farmer'), there is another possible interpretation that is highly unlikely to correspond to any real-world situation ('the cow used an ax somehow to injure the farmer').

The ambiguity here has to do with the prepositional phrase with ax. In the intended interpretation, with ax modifies the noun farmer. In the alternative interpretation, with ax modifies the larger phrase injures farmer.

One way to represent this structural difference is with syntactic trees. Look closely at the following representations of the sentence The cow will injure the farmer with an ax:

For now, you don’t need to understand why the nodes of the tree are labeled as they are (although you may have guessed that PP stands for prepositional phrase and VP stands for verb phrase). The important thing to understand is that each XP label corresponds to a constituent – that is, all the words underneath it are ‘grouped together’ so that they behave as a syntactic unit. Notice that each constituent can potentially contain another constituent. This reflects the fact that human language is recursive.

Some of the constituents of tree (a) include:

In English, any DP constituent (no matter how many words it contains) can be replaced with a pronoun. For example, we can replace the DP the farmer with an ax with the pronoun him, and the sentence will still be grammatical:

This is an example of a constituency test - a way to check whether we have correctly analyzed the constituents of a sentence.

Now look at tree (b). Notice that the PP with an ax is located in a different place – it is no longer grouped together with the farmer under a single DP node. In other words, the farmer with an ax is no longer a constituent, since it does not exhaust the contents of any single node in the tree.

We can still substitute the object DP with a pronoun, but the resulting sentence will be different from the sentence in (a'):

Questions

The following two sentences are structurally ambiguous. Write a paraphrase of each interpretation for each sentence. Make sure your paraphrases are clearly unambiguous - if you want, you can draw pictures to help disambiguate the sentences.

Now draw two trees (similar to those shown in (a) and (b)) that correspond to the ambiguous sentence The students will discuss some problems with the teachers. Label your trees 'Interpretation 1' and 'Interpretation 2' depending on what you wrote in the blanks above.

We recommend that you use a program called Trees Player to draw your trees. Here's how:

If you are unable to use the Trees program for whatever reason, you can draw your trees by hand. Use the trees in (a) and (b) as a guide.
