Introduction This paper attempts to analyze English word order change within optimality theory (OT). It focuses mainly on the word order c h a n g e f r o m S O V t o S V O , Ve r b - S e c o n d p h e n o m e n o n ( V 2 ) , a n d t h e l o s s o f V 2 .

Va n K e m e n a d e ( 1 9 8 7 , 1 9 9 7 ) , b a s e d o n K o s t e r ’ s a n a l y s i s o n D u t c h (1975), argues that Old English (OE) is an SOV language with Ve r b - M o v e m e n t i n r o o t c l a u s e s , a s s h o w n b e l o w : (1) Þæt he his stefne up ahof that he his voice up lifted ‘that he lifted up his voic (Pintzuk 1999: 49, Bede 154.2 8) (2) Þa ge-mette he sceaðan then met he robbers ‘then he met robbers’ (Pintzuk 1999: 91, ÆLS 31.151) A finite verb (Vf) is preceded by its complement in non -root clauses as in example (1). In root clauses as shown in example (2), V f appears as the second constituent of the clause, regardless of the grammatical function of the initial constituent. Va n Kemenade (1987, 1997) states that there occurred two important structural changes in Middle English (ME): the underlying word order change from SOV to SVO and the loss of V2. Let us look at t h e m i n d i v i d u a l l y. The underlying word order change from SOV to SVO was completed by 1200. Illustrative examples of a non -root clause and a r o o t c l a u s e a r e g i v e n i n ( 3 ) a n d ( 4 ) , r e s p e c t i v e l y. N o t e , h o w e v e r, t h a t V2 was still alive, so that the movement of Vf to the head of CP was required in root clauses. (3) gif Þet tu wilnest were Þe muche wlite habbe if that you desire man that much beauty have ‘If you want a beautiful husband ’ ( Va n K e m e n a d e 1 9 8 7 : 1 7 9 , H M , 2 0 . 8 ) (4) Þa ge-mette he sceaðan then met he robbers ‘then he met robbers’ (Pintzuk 1999: 91, ÆLS 31.151) The second change relevant to English word order in ME is the loss of V2, which took place around 1400. This is shown in (5): (5) Sothely Þe ryghtwyse sekys Þe Ioye and … truly the righteous seeks the joy and … ‘ Tr u l y t h e r i g h t e o u s s e e k s t h e j o y a n d … ’ ( Va n K e m e n a d e 1 9 8 7 : 1 8 2 , R R , 4 , 24) In example (5) with the topic sothely, the verb sekys does not occupy the second position of the clause. This paper is organized as follows: in section 2, I introduce six relevant constraints to analyze the word order change from SOV to SVO, V2, and its loss. Secti on 3 shows how OT analyzes these word order changes. Section 4 draws a conclusion. 2. The relevant constraints In order to account for the word order changes indicated above, I will introduce the following six constraints: The first constraint that is relevant here is TP -SCOPE: (6) TP-SCOPE: A topic must move to the position that c -commands the entire sentence. The function of this constraint is to force a topic specified in the input1 to move into the initial position of a clause. The second constraint is TP -SPEC: (7) TP-SPEC: A topic that is specified in the input must move to a specifier position. M o r e p r e c i s e l y, T P - S P E C r e q u i r e s a t o p i c s p e c i f i e d i n t h e i n p u t t o move to [Spec, CP], since [Spec, IP] has already been occupied by a s u b j e c t a n d [ S p e c , V P ] m u s t b e s a v e d f o r c h e c k i n g , a s s h o w n i n ( 11 ) below: The OB-HD: third constraint that plays an important role here is (8) OB-HD: A projection has a head. (Grimshaw 1997: 374) T h e f o u r t h c o n s t r a i n t i s S TAY, t h e f u n c t i o n o f w h i c h i s t o f o r b i d movement: ( 9 ) S TAY: Tr a c e i s n o t a l l o w e d . (Grimshaw 1997: 374) The fifth constraint works in non -root clauses as shown below: (10) PURE-EP: No adjunction takes place to the highest node in a subordinate extended projection; and no movement takes place into the highest head of a subordinate extended projection. (Grimshaw 1997: 374) T h e s i x t h a n d t h e l a s t c o n s t r a i n t i s S AT I S F Y: ( 11 ) S AT I S F Y: Morpho-syntactic features must be checked in a specifier position.2 (Speas 1997: 176) This constraint forces a complement of Vf to move to [Spec, VP] for checking. According to Speas (1997), all phrases are base -generated h e a d - i n i t i a l l y. T h e i n t e r a c t i o n b e t w e e n S AT I S F Y a n d S TAY d e c i d e s whether a head precede its complement or not in a language. I will assume, following Speas (1997), that a complement is always preceded by a head in its base - position and demonstrate that the wor d order change from SOV to SVO completed by 1200 can be attributed to reranking of the constraints. 3. An analysis of English word order change within OT 3.1 An account of non-root clauses Having introduced the relevant constraints, let us consid er how t h e c o n s t r a i n t s i n t e r a c t w i t h e a c h o t h e r. I b e g i n m y e x p l o r a t i o n b y analyzing the word order change from SOV to SVO observed clearly in non-root clauses and then turn to V2 and its loss in root clauses. 3.1.1 Old English Let us first analyze OE non-root clauses using the four relevant c o n s t r a i n t s : O B - H D , S TAY, P U R E - E P, a n d S AT I S F Y. T h e c o n s t r a i n t s TP-SCOPE and TP-SPEC are not relevant here, since all of the candidates vacuously satisfy them. Suppose that OE has the following ranking: ( 1 2 ) P U R E - E P, S AT I S F Y > > S TAY > > O B - H D I n r a n k i n g ( 1 2 ) , P U R E - E P a n d S AT I S F Y a r e e q u a l l y r a n k e d , w h i c h o u t r a n k S TAY, w h i c h i s i n t u r n u n d o m i n a t e d b y O B - H D . T h e p a r t i a l r a n k i n g o f S AT I S F Y o v e r S TAY i m p l i e s t h a t i t i s m o r e i m p o r t a n t t o move a complement of Vf to [Spec, VP] than to prohibit such movement. The following tableau of the sentence Þæt he his stefne up a h o f d e m o n s t r a t e s t h e c o r r e c t n e s s o f r a n k i n g ( 1 2 ) . Ta b l e a u ( 1 3 ) s h o w s the key competitors: (13) Þæt ({up ahof(x,y), x=he, y= his stefne, tense=past}) PUREEP S AT I S F Y a. ☞[ CP Þæt [IP he e [VP his stefnei up ahof ti]]] b. [CP Þæt [IP he ahofj [VP his stefnei up tj ti]]] c. [ CP Þæt [IP he e [VP ahof his stefne]]] Candidate (a) has OBHD * * ** *! up violations S TAY of S TAY * and OB -HD, since the complement his stefne moves to [Spec, VP] and the head of IP is not f i l l e d . T h e t w o v i o l a t i o n s , h o w e v e r, p r o v i d e t h e b e s t w a y t o s a t i s f y t h e top-ranked constraints. Candidate (b), with the movements of the c o m p l e m e n t a n d V f t o [ S p e c , V P ] a n d t h e h e a d o f I P, r e s p e c t i v e l y, v i o l a t e s S TAY t w i c e .

Ta b l e a u ( 1 3 ) c o r r e c t l y s e l e c t s c a n d i d a t e ( a ) w i t h t h e l e a s t s e r i o u s violations as optimal. 3.1.2 Early Middle English Let us turn to non-root clauses in Early Middle English (EME). B a s e d o n Va n K e m e n a d e ’ s a n a l y s i s ( 1 9 8 7 , 1 9 9 7 ) , t h e b a s e c h a n g e f r o m SOV to SVO was completed by 1200, as example (3) illustrates. Given this analysis, ranking (12) is considered to have changed as in (14): ( 1 4 ) P U R E - E P, S TAY > > S AT I S F Y, O B - H D I n r a n k i n g ( 1 4 ) , P U R E - E P a n d S TAY a r e t i e d , d o m i n a t i n g S AT I S F Y a n d O B - H D . T h e p a r t i a l r a n k i n g o f S TAY o v e r S AT I S F Y p r e d i c t s t h a t a complement of Vf would occupy its underlying position. The correctness of this ranking is shown in tableau (15): (15) gif Þet({wilnian(x,y), x tu, were Þe muche wlite habbe, tense=present y= PURE -EP subjunctive }) a. [CP gif Þet [IP tu e [VP were Þe muche wlite habbei wilnest ti]]] b. [CP gif Þet [IP tu wilnestj[VP were Þe muche wlite habbei tj ti]]] c. ☞ [CP gif Þet [IP tu e[VP wilnest were Þe muche wlite habbe]]] S TAY S AT I S F Y *! OBHD * *!*! * * Ta b l e a u ( 1 5 ) r i g h t l y s e l e c t s c a n d i d a t e ( c ) w i t h S V O o r d e r a n d t h e least serious violations as optimal. 3.2 An OT account of root clauses Having demonstrated that the word order change from SOV to SVO observed mainly in non -root clauses was caused by reranking of (12) to (14), let us turn to V2 and the loss of V2 in root -clauses using the five constraints, TP -SCOPE, TP-SPEC, OB-HD, S TAY, and S AT I S F Y. 3 3.2.1 Old English Suppose that in OE the five constraints are ranked as in (16): ( 1 6 ) T P - S C O P E , T P - S P E C , O B - H D , S AT I S F Y > > S TAY S TAY i s d o m i n a t e d b y t h e f o u r c o n s t r a i n t s , w h i c h a r e t i e d w i t h e a c h o t h e r.

Ta b l e a u ( 1 7 ) i l l u s t r a t e s r a n k i n g ( 1 6 ) : (17) {gemetan (x,y), z=topic, x=he, y= sceaðan, z=Þa, tense=past} a. ☞ [CP Þai ge-mettej[IP he tj [VP sceaðank tj tk ti]]] b. [CP Þai ge-mettej[IP he tj [VP tj sceaðan ti ]]] c. [CP Þai e[IP he gemettej [VP sceaðank tj tk ti]]] d. [IP Þai [IP he e[VP gemette sceaðan ti]]] e.

S u c h v i o l a t i o n s , h o w e v e r, h a v e t h e b e n e f i t o f s a t i s f y i n g t h e higher-ranked remains in constraints. situ, has one Candidate (b), wher e S AT I S F Y and three the complement S TAY violations. C a n d i d a t e ( c ) l a c k s t h e h e a d o f C P, r e s u l t i n g i n o n e O B - H D a n d t h r e e S TAY v i o l a t i o n s .

Candidate (e) respects TP -SPEC and TP-SCOPE by moving the topic to [Spec, CP], but incurs two OB -HD violations due to the lack of the h e a d s o f I P a n d C P. Ta b l e a u ( 1 7 ) d e m o n s t r a t e s t h a t c a n d i d a t e ( a ) i s a winner and the others are all losers under the ranking in (16). A c t u a l l y, c a n d i d a t e ( a ) i s g r a m m a t i c a l i n O E g r a m m a r. 3.2.2 Early Middle English L e t u s t u r n t o E M E r o o t c l a u s e s . N o t e , h o w e v e r, t h a t t h e s u r f a c e structure of root clauses in EME is the same as that in OE. Compare example (2) in OE and example (4) in EME. Both of them have the following schematic structure, with the topic in the initial position ([Spec, CP]) and Vf in the second position (the head of CP). (18) leaves out traces to simplify exposition: (18) [CP topic Vf [IP subject [VP complement]]] This comes from the fact that the word order change from SOV to SVO does not directly affect the loss of V2 that had existed after 1200. Thus, the movement of Vf to the head of CP masks the interaction b e t w e e n S AT I S F Y a n d S TAY. I a s s u m e , f o l l o w i n g Va n K e m e n a d e ( 1 9 8 7 , 1997), that example (2) and example (4) have different structures by analogy with non-root clauses shown in examples (1) and (3). Given this assumption, the ranking in (16) can be considered to have changed by 1200 to the following: ( 1 9 ) T P - S C O P E , T P - S P E C , O B - H D > > S TAY > > S AT I S F Y I n E M E , S TAY i s r a n k e d o v e r S AT I S F Y, w h i c h i s t h e r e v e r s e r a n k i n g of the one proposed for OE. The following tableau shows how a grammatical sentence is chosen as optimal: (20) {ahof up(x,y), z=topic, x=Pauls, y=his heafod, z= Þa, tense=past} a. [CP Þai ahofj [IP Paulus tj [VP his heafodk tj up tk ti]]] b. ☞ [CP Þai ahofj [IP Paulus tj [VP tj up his heafod ti]]] c. [CP Þai e [IP Paulus ahofj [VP his heafodk tj up tk ti]]] d. [IP Þai [IP Paulus e[VP ahof up his heafod ti]]] e. [CP Þai e [IP Paulus e[VP ahof up his heafod ti]]] TP-SCO PE TP-SP EC OBHD S TAY S AT I S F Y **** *** *! * *! *** *! * * *!*! * * As tableau (20) shows, candidate (b), where the complement stays in situ, is optimal in EME. 3.2.3 Late Middle English Let us examine root clauses in Late Middle English (LME). A c c o r d i n g t o Va n K e m e n a d e ( 1 9 8 7 , 1 9 9 7 ) , V 2 w a s l o s t b y 1 4 0 0 , a s example (5) shows. It follows that ranking (19) was reranked as in (21) by 1400: ( 2 1 ) T P - S C O P E > > S TAY > > O B - H D , S AT I S F Y > > T P - S P E C I n r a n k i n g ( 2 1 ) , T P - S C O P E d o m i n a t e s S TAY, s o t h a t a t o p i c m o v e m e n t i s r e q u i r e d . T P - S P E C a n d O B - H D a r e , h o w e v e r, d o m i n a t e d b y S TAY. Thus, a topic cannot move to [Spec, CP], contrary to OE and EME grammars. The following tableau illustrates this: (22) {sekys(x,y), z=topic, x= Þe ryghtwyse, y= Þ e I o y e , z = s o t h e l y, tense=present} a. [CP Sothelyi sekysj[IP Þe ryghtwyse tj [VP Þe Ioyek tj tk ti]]] b. [CP Sothelyi sekysj [IP Þe ryghtwyse tj [VP tj Þe Ioye ti]]] c. [CP Sothelyi e[IP Þe ryghtwyse sekys j [VP Þe Ioyek tj tk ti]]] d. ☞ [IP Sothelyi [IP Þe ryghtwyse e [VP sekys Þe Ioye ti]]] e. [CP Sothelyi e[IP Þe ryghtwyse e[VP sekys Þe Ioye ti]]] TP-SCO PE S TAY OBHD S AT I S F Y TP-SP EC **** *** * *** * * * * * ** * * Candidate (d) with the topic sothely adjoined to IP is optimal in LME. This results in the loss of V2. 4. Conclusion This paper has analyzed the word order changes within OT and illustrated the applicability of OT to historical syntax. I have proposed that in non-root clauses, OE and EME have the rankings in ( 1 2 ) a n d ( 1 4 ) , r e s p e c t i v e l y. T h e r a n k i n g s l e a d u s t o t h e c o n c l u s i o n that the word order change from SOV to SVO can be attributed to r e r a n k i n g b e t w e e n S AT I S F Y a n d S TAY: O E r a n k s S AT I S F Y o v e r S TAY, requiring a complement to move to a specifier position in order for features t o b e c h e c k e d .

Further research is needed to determine whether such tendency is found in other constructions. ENDNOTES 1 For the definition of the input, I follow Grimshaw (1997) and Grimshaw and Samek-Lodovici (1998). 2 Note that in my analysis, the base-position of a subject is assumed to be [Spec, IP], rather than [Spec, VP], because [Spec, VP] must be saved in order for features to be checked. 3 In this analysis, subjects are limited to full -NPs.
