Conflict Resolution

Recall: OT is a grammatical architecture thatis constraint based.We discussed the constraints/ representation vs. derivation issue yesterday.The principles/constraints are allowed to be in conflict with each other. A historical perspective on this is today‘s topic.

Precursors and Background: conflict resolution• The notion of conflicts, central to OT, has not

really been identified as such in older theories, though it is evident that conflicts and their resolution played at all times an important role.

• In a nutshell, derivational theories use the device of rule ordering to solve potential conflicts, and representational theories formulate constraints on the kind of phonological structures licensed by Universal Grammar.

Conflicts in derivation and in representations

Formulated from a different perspective :In a derivation model, conflicts between rules arise when two rules are applicable at the same time - so that one has to decide which rule applies, and which rule doesn’t

Rule Ordering in Syntax : Case

A simple example for the need for rule ordering comes from the interaction of Case theory and other rules of grammar.

Suppose that Case is assigned to a noun phrase whenever it stands in a certain local relation to a verb, a preposition, etc ....

Page 7: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Case & wh-Movement

In German, Case must be assigned to a noun phrase BEFORE it is moved to sentence initial position in a question ...

Wen denkst du dass sie liebtwho-acc think you that she loves

... Because the noun phrase would be too far away from the verb after it has been preposed

Page 8: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Case & wh-Movement

This looks like intrinsic rule order in phonology ...Note however that noun phrases sometimes (have to) pick up Case after wh-movement *je crois Jean être intelligentI believe John to be intelligent

qui crois-tu être intelligentwho believe.you to be intelligent

or in Hungarian, in Quechua ...

Page 9: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Case & passive

In German, accusative Case assignment must come later later than than passivization, because otherwise, the wrong Case pattern would be generated

dass der Mann angerufen wirdthat the-nom man called up is

*dass den Mann angerufen wirdthat the-acc man called up is

Page 10: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Case & passive

In Ukrainian, Hebrew, North Russian and other languages, accusative Case may, however, show up in passives.

We thus need extrinsic rule ordering, tooGerman: passive > accusative Ukrainian:accusative > passive

Conflict Resolution: Pre-OT Models

The leading idea of generativism has always been to formulate as explicit rules for language as possibleThe more explicit and detailed rules are, the less likely they are to run into conflicts ...but recall the problems w.r.t. the loss of generalizations, etc.

Kind of conflicts found in phonology

1. Markedness vs. faithfulness

Phonological outputs are torn between the desire to be unmarked, and so fulfill the basic phonology of the language, and the desire to be faithful to their underlying representations, which can be badly marked. These basically conflicting tendencies is found in all domains of phonology.

Page 14: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Markedness

Markedness is a rather vague term, though crucial in phonology. It has received several

different definitions :

•A marked segment is less natural, more complex, less common, not basic, it appears later in language acquisition, in fewer languages, in less positions, it is not readily subject to neutralization, harder to articulate, perceptually more salient, etc.

Page 15: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Markedness

– Nasal vowels are more marked than oral ones (all languages that have nasal vowels also have oral ones)

– Voiced obstruents are more marked than voiceless ones (obstruents have a tendency to be voiceless).

– Voiced sonorants are less marked than voiceless ones (sonorants have a tendency to be voiced).

– Open syllables are less marked than closed ones.

Page 16: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Markedness

Some diagnostics for markedness:- Implication: the marked feature or segment implies the unmarked one.- Frequency: unmarked features are more frequent than marked ones.- Processes: the marked features emerge only under special circumstances (otherwise emergence of the unmarked), the unmarked feature neutralizes more easily.

Page 17: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Markedness vs Faithfulness

A further example for unmarkedness: the most unmarked syllable structure is an open syllable with an onset (CV).Languages are confronted with inputs which cannot be syllabified straightforwardly in a series of CVs. Some languages are faithful to their inputs (German Strumpfs ‘sock, gen.’), Others prefer unmarkedness (Arbeit ‘work’ in Japanese is aribaatu, and the expression merry Christmas in Hawaiian is mele kelikimaka).

Page 18: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Markedness vs Faithfulness

In a purely derivational model, rules are expressed which account for repair.Examples of rules responsible for the absence of coda:C –> Ø / V _ CØ –> V / C_C

But remember that rules can be formulated whose aim is the reverse of unmarkedness, because the format of the rules does not show their aim.

Page 19: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Markedness vs FaithfulnessIn a representational model, syllable templates are postulated to which the individual segments dock to.Unsyllabifiable segments are either deleted or licenced through creation of a new syllable (vowel epenthesis). Remember Palestinian Arabic. / | \ / | / | \ C V C –> C V C V C d a r s d a r i s

Page 20: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Markedness vs Faithfulness

Representations do not really escape rules. However the aim of processes has become much clearer, since now, the aim of a rule is included in its format.•A vowel is epenthesized in order to allow the syllabification of an otherwise unsyllabifiable C.•It is not possible to formulate a rule which is ill-formed w.r.t. a certain representation.Remember the possible and impossible assimilations of last time.

Page 21: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Markedness vs Faithfulness

Hiatus avoidance is another example for markedness vs faithfulness.

Last time we only saw examples of languages which avoid hiatus, at least in some circumstances, thus of languages favoring unmarkedness.Some languages (Maori, Hawaiian) tolerate hiatus much more easily. These languages favor faithfulness.

Page 22: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Avoidance of hiatus

The languages of last time have cases in which hiatus is not repaired, however.

First French and consonant deletion: L’ami vs elle a un enfant.

In the case of l’ami, schwa in the article is elided. Notice that part of the article is still present and pronounced.

Page 23: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Avoidance of hiatus

In elle a un enfant, a or un can not be elided, since elision would lead to complete deletion of the morpheme. Elle un enfant or elle a enfant.

The tendency to unmarkedness can be hindered by a more important tendency (here the tendency to realize morphemes phonetically).

(This is a case of do something except when…)

Page 24: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Avoidance of hiatus

In rule ordering, the restriction against vowel deletion in case it stands for a whole morpheme is difficult to express. It is a restriction on the environment of the rule application.V –> Ø/ –V (except when …)(It is not an elsewhere condition, since elsewhere condition concerns two rule, the environment of one includes the environment of the other.)

Page 25: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Avoidance of hiatus

In a representational model, it is again the tendency to unmarked syllable structure which triggers the process.

/ \ | / | C V V –> C V l e ami l a mi

Page 26: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Avoidance of hiatus

Second case, consonant insertion in German:

Cha?ót vs Théo

A consonant is inserted between two vowels in a hiatus position, except when the second syllable is unstressed.In one case markedness wins (when a glottal stop is inserted), in the other case, faithfulness wins.

Page 27: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Avoidance of hiatus

The intuition is that it is more important for a stressed syllable than for an unstressed syllable to begin with a consonant.In rule ordering, we have stress assignment first, then glottal stop insertion.In other words syllable structure, stress assignment, then again syllable structure (repair).

Page 28: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Avoidance of hiatus

In a representational model, we need to require a consonant at the beginning of a foot (since a stressed syllable begins a foot).

F/ \

/ | \ /|\ ÷ A l pen

Page 29: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Avoidance of hiatus

In Maori and Hawaiian (in some contexts, since Hawaiian has glide formation in some other environments), faithfulness wins.There is just no rule repairing hiatus.In a representational model, syllables do not need onsets.

Page 30: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Avoidance of hiatus

Comparing French, German and Maori, the fact that syllable templates are different in the three languages must be formulated as an independent fact of the language.

It is an accident that Maori tolerates more onsetless syllables than English and German and that German requires onsets for their stressed syllables.

Page 31: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Kind of conflicts found in phonology

2. Markedness vs. markedness

• Different modules of phonology make different predictions.

• One aspect of phonology can require some kind of unmarked structure and another aspect some other unmarked structure for the same segmental or

syllabic material.

Page 32: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Metrical phonologyA good place to look for conflicts between 2 kinds of markedness is Metrical phonology.

Trochaic-Iambic Law (Hayes 1995)A canonical trochee (') consists of two equal syllables, in which both s have the same weight, (mono- or bimoraic, or just syllables). In contrast, a canonical iamb (') consists of unequal syllables: is lighter than '

Page 33: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Metrical phonology

This requirement is conflicting with the requirement that all syllables have the structure CV. •To produce good iambs, French lengthens the last syllable but Beduin Arabic reduces the first syllable. Kitib becomes k.tib (McCarthy 2000)The first syllable looses its vowel and becomes badly marked. However it is more important for the language to respect the requirement of a good iamb.Final [b] is extrametrical.

Page 34: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Metrical phonology

•A purely derivational approach to phonology has problems with metrical facts. SPE proposed a complex system of ordered rules to account for stress in English, in which stress was an ordinary feature [±stress] but as Liberman & Prince showed, some of the basic properties of stress cannot be accounted for in such a model.

Page 35: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Metrical phonology

The special properties of stress (in comparison with segmental features)

•- stress is associated with a syllable (not to a segment)•- relativity (a syllable is stressed only in comparison with an adjacent unstressed or less stressed one)•- no invariant phonetic correlate•- no assimilation

Representational approach of Liberman & Prince:Metrical tree w s / \ / \ w s / s / \ / \ / / \ s w s w w s w Belgian farmers grow turnips

Metrical phonology

Prince (1990), Hayes (1995) and others proposed an inventory of feet, to which syllables associate.

However, a great deal of repairs are necessary (extrametricaliy, degenerate feet and the like)

OT is more elegant.

Kind of conflicts found in phonology

3. Alignment and other requirements

The last kind of conflict that will be mentioned today has to do with alignment effects.Some phonological entities want to be as near the edges of constituents as possible. This is true of stress for instance.Some other entities want to be associated with entities of a different kind as themselves.

Page 40: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

AlignmentTones of intonation languages want to be associated with syllables of a certain kind: pitch accents with accented syllables, boundary tones with final syllables.

Tones of tone languages want to be assiciated with syllables in a one-to-one fashion. The ideal autosegmental representation is the one in which there is exactly one tone per syllable and one syllable per tone. However, this is not always possible to fulfill.

Page 41: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Alignment

Melodies, say HLH or HL, have been shown by Goldsmith, Leben, Williams and others to exist independently of words.And of course, words exist independently of melodies. In a HLH melody, the perfect tone-to-syllable association only obtains in case the word the melody associates with is three syllables long, otherwise there is a conflict between the number of tones and the number of syllables.

Page 42: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Alignment•Usually, tone and syllable association takes place left-to-right on a one-to-one basis until no tone is left. Then the last tone associates with the remaining syllables (spreading).• In a rule format, this kind of association is impossible to describe.•It is thus no accident that the first mainstream nonlinear phonological theory (so-called autosegmental phonology) has been developed first for tone phonology.

Page 43: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Alignment

•Syllables and tones are represented on different tiers and association procedes in a certain way (one-to-one, from left-to-right etc.)•However, as in the case of stress, autosegmental representations are not enough. Rules are still necessary to decide how deviant cases of tone association are decided.

Page 44: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Alignment

•A famous case is the so-called Meeussens Law: H # H --> H # L (Dissimilation rule)In Shona

né#hóvé –> né#hove Iteration from left to right: sé#né#hóvé –> sé ne hóvé *sé ne hove

This is a rule, applying on a representation.

Page 45: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Alignment

Autosegmental phonology as a mixture of representation and ordered rules was very successful. Its methods were generalized on other domains of phonology, like metrical and segmental phonology.

Page 46: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Alignment

Remember the problems that were identified last time w.r.t. ordered rules:- unconstraindedness- duplication- conspiracyThe addition of a representational component to phonology was really a progress, because the uncontraindedness was not a concern anymore.

Page 47: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Alignment

But no nonlinear model can resolve the problem of duplication or conspiracy.

Duplication is probably even more acute in representations than in rules.

Conspiracy is not resolved

Conflicts in Syntax

As we will see, the distinction between markedness, faithfulness, and alignment constraints can be made in syntax, too.We will focus now on the issue of how conflicts between constraints have been treated/circumvented in GB theory

Page 50: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Disguised Conflicts in GB

In a representational model such as GB, there seems to be no need for conflict resolution à la rule ordering.

At least the intrinsic rule ordering case discussed above (wh-movement and Case) can be restated easily in terms of trace theory:

who do you think that she loves tCase goes to t and is then transmitted

Page 51: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Disguised Conflicts in GB

But for the correct account of the passive, we still need to assume that passivization precedes Case assignment ...

This is a matter or architecture in GB: passivization happens in the lexicon, and therefore precedes even D-structure ...

Page 52: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Disguised Conflicts in GB

It may thus seem not unlikely that GB shifted its conflicts into the grammatical architecture.

And there is some evidence that this is a correct view ...

Constraints at D-S and at S-S

It is a consequence of the theory of thematic roles that an object should be the first sister of the verb to which is belongs semantically:

I think that John loves Mary*I think Mary that John lovesHe told Mary that it was rainingHe told that it was raining Mary

But in a passive, the semantic object placed in front of the subject position

he was invited _ by Mary

and in a raising situation, it moves even further

he seems to be invited _ by Mary

Constraints at D-S and at S-S

A conflict between EPP* and the theta-theory is avoided in GB by two assumptions:

EPP* need not not hold at D-structure (so that D-S can be constructed without a conflict with EPP*)

The theta-theory is respected at S-structure due to trace theory

Constraints at D-S and at S-S

The arguments that theta-theory must hold after D-S are not very compelling, however ...

No movement into theta-positionsbut these are not empty ... but these have no „attraction“ potential

Constraints at S-S and LF

The idea that wh-movement might take place before or after S-structure, but in any event before LF, was very popular.

Preliminary Summary

GB-theory tries to avoid acknowledging the existence of conflict between constraints by- postulating invisible elements (traces, empty expletive)- having principles apply at certain „levels of representation“ only

Conflict Resolution in GB

There is one domain only where Chomsky 1981 acknowledges conflicting rules: John prefers PRO going to the movies*John prefers his going to the movies

John and his cannot be coreferent in the second example - unlike what we have in:

John prefers his cat

Page 70: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Conflict Resolution in GB

Chomsky‘s solution:

The AVOID PRONOUN PRINCIPLEDo not use an overt pronoun when an empty one is possible.Similar effects:il veut PRO venir he wants come

il veut qu’il vienne he wants that he come

The two il cannot be coreferential because of APP

Preparing the Minimalist Program

In the late eighties, syntacticians became more and more aware of the need to give an account for the question of WHY rules apply.

Given certain representational constraints, one may wonder how they should be met

Page 76: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Preparing the Minimalist Program

A paradigm such asthere seems t to be a man in my gardena man seems t to be t in my garden*there seems a man to be in my gardenis difficult to understand in GB theory -- why should a man not be able to move to the intermediate position?

Page 77: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Preparing the Minimalist Program

The „minimalist“ answer:

A phrase can move only if this is necessary for the fulfillment of grammatical principles

The principle in question are representational constraints such as the EPP or the Case Filter

Page 78: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

Preparing the Minimalist Program

According to Pesetsky, rules should apply as early as possible to meet requirementsAccording to Chomsky 1991, movement applies preferentially afterS-structure. Language particular processes (such as do-insertion) are last resort process, that apply only if nothing else helps ...

Page 79: Conflict Resolution Plan of Today’s Presentation 1. Discuss conflict resolution as rule ordering 2. Introduce types of conflicts 3. Discuss the disguised

The Minimalist Program

The Minimalist Program assumes that phrases should not be moved (ECON)

This constraint can be overriden by the need to check features (LEG)

Movement is visible, however, only if the pertinent features are strong

Strength determines if LEG or ECON wins
