Derivations The steps are not necessarily a reflection of what we are doing online as we speak—what we are doing is characterizing our knowledge of language, and it turns out that we can predict our intuitions about what sentences are good and bad and what different sentences mean by characterizing the relationship between underlying thematic relations, surface form, and interpretation in terms of movements in an order with constraints on what movements are possible.

Derivations It seems that the simplest explanation for the complex facts of grammar is in terms of several small modifications to the DS that each are subject to certain constraints, sometimes even things which seem to indicate that one operation has to occur before another could.

Quantifiers We interpret Bill saw everyone as We interpret Bill saw everyone as For every person x, Bill saw x. For every person x, Bill saw x. This is the meaning. This is the logical form of the sentence Bill saw everyone. In the notation of formal logic, this is written as  x. Bill saw x ‘For all x (x a person), Bill saw x.’ This is the meaning. This is the logical form of the sentence Bill saw everyone. In the notation of formal logic, this is written as  x. Bill saw x ‘For all x (x a person), Bill saw x.’

Quantifiers Every boy hates his roommate. Every boy hates his roommate. Notice that each boy hates a different roommate, the roommates are specific to each boy. Notice that each boy hates a different roommate, the roommates are specific to each boy. For every boy x, x hates x’s roommate. For every boy x, x hates x’s roommate. This means that every boy doesn’t just mean the group of boys; rather it goes through the set of boys and says something about each of them individually. This means that every boy doesn’t just mean the group of boys; rather it goes through the set of boys and says something about each of them individually.

Quantifiers These phrases which don’t refer to specific people/things in the world but rather seem to do things to sets of people/things are quantifiers. Examples include: These phrases which don’t refer to specific people/things in the world but rather seem to do things to sets of people/things are quantifiers.

Why believe in QR? The thing is: QR is invisible, it is supposed to happen between SS and LF, and since SS is (the basis for) the structure we hear, we can’t hear its effects—the effect shows up only in the meaning. The thing is: QR is invisible, it is supposed to happen between SS and LF, and since SS is (the basis for) the structure we hear, we can’t hear its effects—the effect shows up only in the meaning.

 QR Another reason to believe in QR: Another reason to believe in QR: What did Sue buy? What did Sue buy? Pick the x such that Sue bought x. Pick the x such that Sue bought x. The interpretation of wh-words has the same kind of operator-variable structure that quantifiers do. The interpretation of wh-words has the same kind of operator-variable structure that quantifiers do. The difference is that wh-movement happens where we can see it, but it still leaves a variable behind, bound by the quantifier (wh-word).

How is this different from How is this different from Who i t i likes his i roommate? Who i t i likes his i roommate?

WCO *Who i does his i roommate like t i ? *Who i does his i roommate like t i ? Who i t i likes his i roommate? Who i t i likes his i roommate? The difference lies in the fact that the wh-phrase had to cross over the coindexed pronoun on its way to SpecCP. This appears to be impossible, and we can state this as follows: The difference lies in the fact that the wh-phrase had to cross over the coindexed pronoun on its way to SpecCP. This appears to be impossible, and we can state this as follows: Weak Crossover (WCO): A coindexed pronoun cannot intervene between a quantifier and its variable.

VP ellipsis So, as long as two VPs in sequence look identical (where traces of movement look identical to one another—they sound the same), we are allowed to pronounce the second one very quietly. So, as long as two VPs in sequence look identical (where traces of movement look identical to one another—they sound the same), we are allowed to pronounce the second one very quietly.

A new position One difference between QR (adjunction to TP) and movement to SpecTP is in the motivations. One difference between QR (adjunction to TP) and movement to SpecTP is in the motivations. Moving to SpecTP or moving to SpecCP is motivated by some need of T (EPP: SpecTP must be filled) or C ([+WH] C needs a [+wh] in its specifier). Moving to SpecTP or moving to SpecCP is motivated by some need of T (EPP: SpecTP must be filled) or C ([+WH] C needs a [+wh] in its specifier). Moving a quantifier (QR) is required because the quantifier needs to get out of the TP (for interpretation). TP itself has no need for quantifiers.

The wh-typology Yet in all of these languages, the meaning of What did Bill give to whom? is the same… Yet in all of these languages, the meaning of What did Bill give to whom? is the same… Pick the x, pick the y, such that Bill gave x to y. Pick the x, pick the y, such that Bill gave x to y. The meaning has a quantificational (operator-variable) structure, so if the meaning (logical form) in all of these languages is derived from LF, these quantifier-variable chains must be there at LF.

We see the wh-phrases moving in Bulgarian. But we know from the meaning that all of these movements have to happen in all languages.

The wh-typology We conclude then that languages differ not in whether they move all of the wh- words to the front of the sentence—they all do—but rather in when they move them there. We conclude then that languages differ not in whether they move all of the wh- words to the front of the sentence—they all do—but rather in when they move them there. Bulgarian: All between DS and SS. Bulgarian: All between DS and SS. Japanese: All between SS and LF. Japanese: All between SS and LF. English: One between DS and SS, the rest between SS and LF. English: One between DS and SS, the rest between SS and LF.

The wh-typology We can phrase this in terms of overt and covert movement: We can phrase this in terms of overt and covert movement: Bulgarian: All wh-movement is overt. Bulgarian: All wh-movement is overt. Japanese: All wh-movement is covert. Japanese: All wh-movement is covert. English: One wh-phrase moves overtly, the rest move covertly. English: One wh-phrase moves overtly, the rest move covertly.

Derivations This allows us a fairly uniform view of languages. This allows us a fairly uniform view of languages. Across languages, DS is basically the same (theta requirements, functional projections). Across languages, DS is basically the same (theta requirements, functional projections). Across languages, LF is basically the same (meanings, scope, etc.). Across languages, LF is basically the same (meanings, scope, etc.). This means that across languages, the movements that happen between DS and LF are basically the same. This means that across languages, the movements that happen between DS and LF are basically the same. What differs is the timing—whether the movements happen before SS or after SS on the way to LF. What differs is the timing—whether the movements happen before SS or after SS on the way to LF.

Derivations So in terms of wh-movement, we can say that the languages pick different parts of the derivation to focus on as SS.

Scope and wh-movement In a wh-question, you have a [+Q], [+WH] C and some wh-words. In a wh-question, you have a [+Q], [+WH] C and some wh-words. The wh-words have to move up to the [+WH] C. From here they have scope over the rest of the question. The wh-words have to move up to the [+WH] C. From here they have scope over the rest of the question. Where the [+WH] C is determines the scope of the wh-phrases. Where the [+WH] C is determines the scope of the wh-phrases. What i C did John say t i that he wanted to buy t i ? What i C did John say t i that he wanted to buy t i ? John knows what i C he wanted to buy t i. John knows what i C he wanted to buy t i.

Superiority Who did Bill persuade to buy what? Who did Bill persuade to buy what? (Bill persuaded Mary to buy a book, he persuaded Larry to buy a coffee table, he persuaded Sue to buy a futon, …) (Bill persuaded Mary to buy a book, he persuaded Larry to buy a coffee table, he persuaded Sue to buy a futon, …) Pick the x, pick the y, such that Bill persuaded x to buy y. Pick the x, pick the y, such that Bill persuaded x to buy y. So both wh-words (who and what) take scope at the matrix clause SpecCP.

Superiority Who did Bill persuade to buy what? Who did Bill persuade to buy what? *What did Bill persuade who to buy? *What did Bill persuade who to buy? It seems that we can’t just choose just any wh-word to move to SpecCP—one works, one doesn’t. What’s the difference between the two?

Superiority There is also a strict ordering for languages where all wh-words move to the front. We take this to also be due to Superiority: There is also a strict ordering for languages where all wh-words move to the front. We take this to also be due to Superiority: cine ce a vazut Romanian who whom has seen ‘Who saw whom?’ cine ce a vazut Romanian who whom has seen ‘Who saw whom?’ *ce cine a vazut whom who has seen ‘Whom did who see?’ *ce cine a vazut whom who has seen ‘Whom did who see?’ The higher wh-word has to move first (by Superiority) and shows up first. The higher wh-word has to move first (by Superiority) and shows up first.

Where have all the wh-words gone? This brings up an interesting question which we haven’t addressed yet—if all of the wh-words are moving (in all languages, some overtly like in Bulgarian and Romanian), where are they going? This brings up an interesting question which we haven’t addressed yet—if all of the wh-words are moving (in all languages, some overtly like in Bulgarian and Romanian), where are they going? English moves its one wh-word to SpecCP. English moves its one wh-word to SpecCP. There is only one SpecCP. There is only one SpecCP. Are the other wh-words not moving to SpecCP? Are the other wh-words not moving to SpecCP?

Where have all the wh-words gone? Following an influential proposal by Rudin (1988), many people assume that the other wh-phrases move up and adjoin to the wh-phrase already in the specifier.

Where have all the wh-words gone? This way, there is still one specifier of SpecCP, but the wh- words are still all in the specifier of SpecCP, one attached to the others.

Subjacency revisited Who knows where we bought what? Who knows where we bought what? (Bill does—he knows all about things bought and places those things were bought from). (Bill does—he knows all about things bought and places those things were bought from). (Bill knows where we bought the coffee table, Mary knows where we bought the futon, …) (Bill knows where we bought the coffee table, Mary knows where we bought the futon, …) The second reading presents a problem. Both who and what take scope at the matrix clause’s SpecCP. What’s the problem? The second reading presents a problem. Both who and what take scope at the matrix clause’s SpecCP. What’s the problem?

Subjacency revisited The same as the problem with The same as the problem with ??What i does Bill know where we bought t i ? ??What i does Bill know where we bought t i ? Moving what here to the matrix SpecCP violates Subjacency, so the sentence sounds somewhat off. Yet: Moving what here to the matrix SpecCP violates Subjacency, so the sentence sounds somewhat off. Yet: Who knows where we bought what? Who knows where we bought what? …sounds fine, even on the “list” reading. …sounds fine, even on the “list” reading.

Subjacency revisited What’s different? Why is the reading with what associated with (moved to) the matrix SpecCP allowed in one case and not the other? What’s different?

Subjacency revisited These sentences would suggest that covert wh- movement is not sensitive to wh-islands. A very widely adopted assumption about Subjacency is made to explain this: These sentences would suggest that covert wh- movement is not sensitive to wh-islands. A very widely adopted assumption about Subjacency is made to explain this: Subjacency only holds for overt movement. Subjacency only holds for overt movement. Because what in Who knows where we bought what? moves covertly, it is no longer subject to Subjacency and can just move directly into the matrix SpecCP. Because what in Who knows where we bought what? moves covertly, it is no longer subject to Subjacency and can just move directly into the matrix SpecCP.

Subjacency revisited This leaves open some loose ends, and people have not reached their final conclusions on whether Subjacency does or does not hold of covert movement.
