(1) ichi*(-rin)-no hana one-cl-gen flower ‘oneflower’ Itisstandardlyconsideredinthecurrentliteraturethatoneofthefactorsthatdistinguish obligatoryclassifierlanguageslikeJapanesefromnon-classifierlanguageslikeEnglishisthe semanticsofnouns(e.g.Borer2005,Bunt1985,Chierchia1998a,b,2010,Krifka2008,Li 2011,Nemoto2005,Rothstein2010,Scontras2013,2014b).Theideaisthatnounsin obligatoryclassifierlanguagesgenerallyhavedenotationsthataresomehowincompatible withdirectmodificationbycountingmodifierslikenumerals,whichincludethosenouns thatcorrespondtocountnounsinotherlanguages,e.g.hana‘flower’. Althoughthisideaisappealing,IarguedinSudo(toappear)thatnominaldenotationsin Japanesearenotsodifferentfromthoseinnon-classifierlanguageslikeEnglish.In particular,Iobservedthattherearecountingmodifiersthatmayappearwithoutclassifiers 1 InSudo(toappear),Iraisedsomeexceptionalexampleswhereclassifiersareoptional.

(someofwhichareincompatiblewithclassifiers)butarenonethelessonlycompatiblewith nounsdenotingcountableobjects.Thesemodifiersincludetasuu‘numerous’andnan-zentoiu‘hundreds’,forexample.SuchcountingmodifiersshowthatJapanesenounscomein twovarieties:thosewhosedenotationsarecompatiblewithcounting,whichIcallcountable nouns(e.g.hana‘flower’),andthosewhosedenotationsareincompatiblewithcounting, whichIcalluncountablenouns(e.g.ase‘sweat’).Adirectconsequenceofthisobservationis thatitshouldnotbethesemanticsofnounsthatrequiresclassifierswithnumerals,contrary tothestandardview,sincecountablenounsareperfectlycompatiblewithnon-numeral countingmodifiersintheabsenceofclassifiers(seeWatanabe2006,Cheng&Sybesma 1999,Bale&Barner2009forrelatedideas). InthepresentpaperIpursueanalternativeexplanationfortheobligatoryuseofclassifiers withnumeralsinJapanese.Themainideaisthatitisthesemanticpropertiesofnumerals, ratherthannouns,thatrequireclassifiersinmodificationcontexts(seeKrifka1995,Bale& Coon2014forsimilarviews).Empiricalmotivationofthisviewcomesfromdatashowing thatnumeralsinJapanesecannotfunctionaspredicatesontheirown,andrequire classifierstodoso.Inordertomakesenseofthisobservation,Iwilldevelopananalysis wherenumeralsinallnaturallanguagesdenoteabstractentitiesbydefault,whichare singulartermsandhencecannotfunctionaspredicatesormodifiers.Iproposethat classifiersturnsuchsingulartermsintopredicates/modifiers.Inordertoaccountforthe differencebetweenobligatoryclassifierlanguagesandnon-classifierlanguages, furthermore,IfollowChierchia’s(1998a,b)ideainassumingthatnaturallanguageis equippedwithaphonologicallysilentoperator,the∪-operator,whichturnssuchsingular termsintopredicates/modifiers,butitsuseisblockedinlanguagesthathavephonologically overtlexicalitemsthatplaythesamerole.Inthepresentcase,therelevantphonologically overtlexicalitemsaretheclassifiers.Consequently,languageswithclassifiershaveto employclassifiersinordertousenumeralsaspredicates/modifiers,whileinnon-classifier languages,numeralshaveadualstatusassingulartermsandpredicates/modifiers. Thepresentpaperisorganizedasfollows.InSection2,Iwilllayoutthecoretheoretical assumptionsandproposals.InSection3,Iwillpresentdatamotivatingtheanalysis proposedinSection2.TheanalysiswillbeextendedinSection4withthedualofthe∪operator,the∩-operator,whichaccountsforfurtherdataofclassifiersinJapanese.Finally,I willconcludeinSection5. 2.NumeralsandClassifiers 2.1Numerals Letusstartwiththemaintheoreticalproposalofthepaper.Firstly,Iassumethatthe extensionsofnumeralsinallnaturallanguagesaresingulartermsbydefault,whichare abstractobjectsoftypen(contrarytoIonin&Matushansky2006;cf.Rothstein2013).For instance,theintensionsofroku‘six’inJapaneseandsixinEnglishareidenticalandlooklike (2),whichisaconstantfunctionfrompossibleworldstoanobjectoftypen.IuseArabic numeralstorepresentobjectsoftypen. (2) ⟦roku⟧=⟦six⟧=λws.6 Rothstein(2013)isanimportantpredecessorofthisidea.Sheassumesthatnumeralshave multiplesemanticfunctionswhicharesystematicallyrelatedviatype-shiftingrules,andthe type-ninterpretationisoneofthem.Iadoptthisviewlateron,butonecrucialdifferent betweenouranalysesisthatshedoesnotseemtoconsiderthetype-ndenotationisthe default.Aswewillsee,thisassumptioniscrucialformyaccountoftheobligatoryuseof classifiersinobligatoryclassifierlanguages. 2.2Classifiers Secondly,IassumeherewithoutargumentsthatinJapanese(andpossiblyinother obligatoryclassifierlanguages),anumeralandclassifierformaconstituenttotheexclusion ofthenounphrase(Krifka1995,Fukui&Takano2000,Doetjes2012).Thus,Iassumethe structureof(1)tobesomethingalongthelinesof(3).2 (3) [ichi-rin]-nohana [one-CL]-GENflower ‘oneflower’ Followingthestandardassumptionintheliteratureonplurality,thedenotationofa countablenounlikehana‘flower’isassumedtobeasinEnglish,exceptthatthenumberis underspecified.Itcontainsallindividualsthatcountassingleflowersandtheirindividualsums(ori-sums). Sinceichi‘one’denotesanobjectoftypen,itcannotdirectlymodifythenounhana.Iclaim thattheroleoftheclassifier-rinin(3)isspecificallytoturnthetype-nobjectintoa modifier.Recallthatthisparticularclassifier-rinisusedforcountingflowersandflowers only.Iassumethatthissortalrestrictionisapresupposition.3Thus,theintensionof-rin lookslike(4).Metalanguagepredicateslikeflowerareassumedtobeonlytrueofatomic individuals,and*floweristheclosureofflowerunderi-sumformation⊔,i.e.*P(x)istrueiff eitherP(x)istrue,orx=y⊔zandboth*P(y)and*P(z)aretrue. (4) ⟦-rin⟧=λws.λnn.λxe:*flowerw(x).|{y⊑x:flowerw(y)}|=n Inwords,thisclassifierensuresthatxisasingleflowerorani-sumconsistingofflowersvia thesortalpresupposition,andcountsthenumberofsingularflowersinx. 2 Someauthorsassumethatclassifierscombinewithnounsfirst,beforecombiningwith numerals(e.g.Chierchia1998b,Krifka2008,Scontras2013,2014b,Watanabe2006).The reasonwhythisisnotadoptedhereisbecausetheanalysistobepresentedbelowwillbe considerablysimplerwiththestructurelike(3).Also,thissyntaxmatchesthesurface structuremoredirectlyatleastinJapanese.InJapaneseanumeralandaclassifierforma singlephonologicalwordtotheexclusionofthenoun.Ileaveitopenhowtoreconcilethe analysisofclassifiersproposedherewiththealternativesyntaxofclassifiers. 3 SeeMcCready(2009)foranalternativeanalysisofthesortalrestrictionasaconventional implicature.AsfarasIcanseethistheoreticalchoiceisinconsequentialforthepurposesof thepresentpaper. Iassumethat(4)combineswithanumeralvia(Extensional)FunctionalApplication,yielding afunctionoftype(s,(e,t)). (5) FunctionalApplication If⟦A⟧isoftype(s,(σ,τ))and⟦B⟧isoftype(s,σ),then⟦AB⟧=⟦ΒΑ⟧=λws: w∈dom(⟦A⟧)&w∈dom(⟦B⟧)&⟦B⟧(w)∈dom(⟦A⟧(w)).⟦A⟧(w)(⟦B⟧(w)). IfollowHeim&Kratzer(1998)inassumingthatfunctionsoftype(s,(e,t))canserveas nominalmodifiersviaPredicateModification. (6) PredicateModification IfAandBarebothoftype(s,(e,t)),then⟦AB⟧=λws.λxe:w∈dom(⟦A⟧)& w∈dom(⟦B⟧)&x∈dom(⟦A⟧(w))&x∈dom(⟦B⟧(w)).⟦A⟧(w)(x)&⟦B⟧(w)(x). Forinstance,thedenotationof(1)iscomputedasfollows(genitivecase-noisassumedto havenosemanticcontribution). (7) a. ⟦roku⟧=λws.6 b. ⟦roku-rin⟧=λws.λxe:*flowerw(x).|{y⊑x:flowerw(y)}|=6 c. ⟦roku-rin-nohana⟧ =λws.λxe:*flowerw(x).|{y⊑x:flowerw(y)}|=6&*flowerw(x) Otherclassifierscanbegivensimilaranalyses.Differentclassifiershavedifferentsortal presuppositionsandcountdifferentkindsofindividuals,asin(8).

(11) KindPredicateModification If⟦A⟧isoftype(s,n)and⟦B⟧isoftype(s,(e,t)),then⟦AB⟧=⟦BA⟧=λws.λxe: ⟦A⟧∈dom(∪)&w∈dom(∪⟦A⟧)&x∈dom(∪⟦A⟧(w))&w∈dom(⟦B⟧)& x∈dom(⟦B⟧(w)).∪⟦A⟧(w)(x)&⟦B⟧(w)(x). Concretely,themeaningofsixflowerswillbecomputedasfollows. (12) a. ⟦six⟧=λws.6 b. ⟦sixflowers⟧=λws.λxe.|{y⊑x:atomicw(y)}|=6&*flowerw(x) IfKindPredicateModification(11)isavailableinJapanesetoo,itwillovergenerate,asthe samederivationas(12)willbecomeavailable.IfollowChierchia’s(1998a,b)insightshere andassumethatKindPredicateModificationisonlyavailableasalastresort.Thatis,if thereareovertlexicalitemsinthelanguagethatdothesamefunctionasasilentoperator, theuseoftheseovertlexicalitemsbecomesobligatory.Inthiscase,thesilentoperatoris the∪-operatorandtheovertlexicalitemsareclassifiers.Whatblocksthederivationlike (12)inJapaneseis,therefore,thepresenceofclassifiersinthelexicon.Thus,thecrosslinguisticvariationbetweenobligatoryclassifierlanguagesandnon-classifierlanguagesboils downtothelexicalinventoryoffunctionalitems.5 3.NumeralsasPredicates Theanalysisproposedabovemakestestablepredictions.Inparticular,numeralsshould alwaysdenotesingulartermsinJapanese,duetothepresenceofclassifiersinthelexicon, andhenceshouldnotbeabletofunctionaspredicates,notjustasmodifiers.Weobservein thissectionthatthisisindeedthecase. 3.1PredicativenumeralsinJapanese 4 Chierchia(1998a,b)assumesthatthe∪-operatorappliesdirectlytokinds,whileIassume thatitappliestoconstantfunctionsoftype(s,n).Thistechnicaldifferenceisimmaterial, giventhatthereisaone-to-onemappingbetweenobjectsoftypenandconstantfunctions oftype(s,n).Thesameremarkappliestothe∩-operatorintroducedbelow. 5 Onepotentialproblemisoptionalclassifierlanguages,towhichIwillcomebackattheend ofthepaper.

SinceEnglishbyassumptionhasnolexicalitemsthatmapobjectsoftypentoproperties, the∪-operatorcanbeusedtotype-shifttheintensionsofnumeralstoproperties.For examplesin(18),weusethecompositionalrule,KindFunctionalApplication(whichis essentiallyparalleltoRothstein’s2013accountofexampleslike(18)).Therearetwo versions,dependingonwhichexpressionservesastheargument. (19) KindFunctionalApplication(version1of2) a. If⟦A⟧isoftype(s,n)and⟦B⟧isoftype(s,e),then⟦AB⟧=⟦BA⟧=λws: ⟦A⟧∈dom(∪)&w∈dom(∪⟦A⟧)&w∈dom(⟦B⟧)&⟦B⟧(w)∈dom(∪⟦A⟧(w)). ∪ ⟦A⟧(w)(⟦B⟧(w)). b. If⟦A⟧isoftype(s,n)and⟦B⟧isoftype(s,((e,t),t))then⟦AB⟧=⟦BA⟧=λws: ⟦A⟧∈dom(∪)&w∈dom(∪⟦A⟧)&w∈dom(⟦B⟧)&∪⟦A⟧(w)∈dom(⟦B⟧(w)). ⟦B⟧(w)(∪⟦A⟧(w)). AsinthecaseofKindPredicateModification,KindFunctionalApplication,whichmakesuse ofthe∪-operator,isassumedtobeunavailableinJapanese,duetothepresenceof classifiersinthelexicon.ThereforetheJapanesecounterpartsof(18)areunacceptable. However,thisanalysisofpredicativenumeralsinEnglishisactuallytoosimple-minded.As pointedouttomebyMartinHackl(p.c.),numeralscannotappearinconstructionsthatare consideredtorequirepredicativeexpressions,e.g.(20b)and(20c). (20) a. Theguestsarethree. b. *Theguestslookthree. c. *Iconsiderthegueststhree. Notealsothatnotonlynumerals,butalsoothernumber-relatedexpressions,e.g.many,are excludedfromtheseconstructions. ThisobservationispotentiallyproblematicfortheaboveanalysisofEnglishwherenumerals haveadualstatusasabstractnumbersandproperties(andhenceisasproblematicfor Rothstein2013).OnewaytosavethecurrentaccountofEnglishnumeralsistoassumethat KindFunctionalApplicationissomehowmadeunusableinconstructionsin(20b)and(20c) butnotin(20a),althoughwhythisshouldbesoisnotcleartome.SinceEnglishandother non-classifierlanguagesarenotofourmaininterestshere,Iwillleavethisissueopenfor futureresearch. 4.MoreonType-nObjects IntheprevioussectionweobservedthatnumeralsinJapanesecannotfunctionas predicatesontheirown.Here,weobservethatnumeral+classifiercanalsodenoteobjects oftypen.Forexample,thefollowingsentences,whichareparallelto(14)and(17b),are alsoacceptable(andperhapsmorenaturalthan(14)and(17b)). (21) a. kyoo-nookyakusan-nokazu-wajuu-ni-nin-da. today-GENguest-GENnumber-TOP10-2-CL-COP ‘Thenumberofgueststodayistwelve.’ b. katteirudoobutsu-nokazu-wayon-hiki-da. have.as.petsanimal-GENnumber-TOP4-CL-COP ‘Thenumberofpets(I)haveis4.’ Thefollowingexamplefurtherreinforcesthispoint. (22) ni-rintasuni-rin-wayon-rin-da. 2-CLplus2-CL-TOP4-CL-COP ‘Twoflowersplustwoflowersmakesfourflowers.’ Iproposetoaccommodatethesedataasfollows.Recallthatthe∪-operatormaps intensionsofnumeralstoproperties.Inadditiontoit,Ialsopostulateitsdual,the∩operator,whichmaps(certain)propertiestoconstantfunctionsoftype(s,n)(cf.Chierchia 1998a,b).Forinstance,whenappliedto∪⟦6⟧.itgivesback⟦6⟧. (23) a. ⟦6⟧=λws.6 ∪ b. ⟦6⟧=λws.λxe.|{y⊑x:atomicw(y)}|=6 ∩ c. (λws.λxe.|{y⊑x:atomicw(y)}|=6)=λws.6 Thus,wehave∩∪⟦6⟧=⟦6⟧.Itisassumedthatthe∩-operatorisapartialfunctionandisonly definedforcertainproperties.Forinstance,thepropertyofbeingaJapanesespeakerliving inLondonhasnotype(s,n)correlate. Iclaimedabovethatthe∪-operatorismadeunusableinobligatoryclassifierlanguageslike Japaneseduetothepresenceofclassifiersinthelexicon.However,sincethereisnoovert lexicalitemthatdothesamethingasthe∩-operator,nothingpreventsitfrombeingusedin Japanese.Iclaimthatthisisexactlywhatisgoingonin(21)and(22).Thatis,itinvolvesan applicationofthe∩-operatortonumeral+classifier. Specifically,Iproposethatthedomainoftypencontainsmoreobjectsthanjustplain numbers.Inparticular,abstractnumbersthatcorrespondtopropertiesofhavingafixed numberofmembersofspecificcategoriesarealsoobjectsoftypen(seeScontras2014a,b forasimilaranalysisdevelopedforthesemanticsofmeasurenounslikeamount).Hereisa concreteexample.Accordingtotheanalysisputforwardhere,numeral+classifierdenotesa property.Forexamplejuu-ni-nin’10-2-cl.human’denotesthepropertyofhavingtwelve humansasparts. (24) ⟦juu-ni-nin⟧=λws.λxe.*humanw(x).|{y⊑x:humanw(y)}|=12 Applyingthe∩-operatorto(24),weobtainaconstantfunctionoftype(s,n)whichmapsany worldtothetype-nobjectthatcorrespondstothepropertyofhaving12humans.Ianalyze (21a)asanidentificationalsentenceinvolvingthisobjectoftypen.ThesubjectDPofthis sentenceisassumedtohaveatype-nobjectasitsextension,andtheentiresentencestates thatthistype-nobjectandthetype-ncorrelateof(24)areidentical.(21b)and(22)canbe analyzedanalogously. Forthesakeofcompleteness,weextendthecompositionalruleofKindFunctional Applicationwithaclausetriggeringthe∩-operator(25c). (25) KindFunctionalApplication(version2of2) a. If⟦A⟧isoftype(s,n)and⟦B⟧isoftype(s,e),then⟦AB⟧=⟦BA⟧=λws: ⟦A⟧∈dom(∪)&w∈dom(∪⟦A⟧)&w∈dom(⟦B⟧)&⟦B⟧(w)∈dom(∪⟦A⟧(w)). ∪ ⟦A⟧(w)(⟦B⟧(w)). b.

Anumberoffurtherquestionsarisefromthisproposal.Firstly,itiscertainlyexpectedthat thepresentanalysisisapplicabletootherobligatoryclassifierlanguages.Inparticular,itis expectedthatnumeralsinallobligatoryclassifierlanguagescannotfunctionaspredicates withoutthehelpofclassifiers.AsIhavenoaccesstoempiricaldatainotherobligatory classifierlanguagesthanJapaneseatthispoint,Ineedtoleavethisquestionforanother occasion.Secondly,theanalysisputforwardheredoesnotsquarewellwiththeexistenceof optionalclassifierlanguagessuchasArmenianandHausa(Borer2005,Bale&Khanjian 2008,2014,Doetjes2012).Itseemsnecessarytosaythatclassifiersintheselanguages somehowdonotblocktheuseofthe∪-operator.Thisisleftasapotentialproblemforthe analysisproposedhere.Thirdly,whyisitthatthereisnoovertlexicalcounterpartofthe∩operatorinEnglishandJapanese?Thiscouldsimplybealexicalaccident,andtheremightas wellbealanguagethathassuchanitem.Furtherresearchisrequiredtodeterminewhether thisisso,butifsuchalanguageisfound,thetheoryproposedheremakesatestable prediction,namely,theuseofthe∩-operatorwillbeblocked.
