He can help us. He can help us, if we ask. 2 Functions of can       (a) He is able to help you.  (b) He is permitted to help you. He can help you. Okay, he can help you. 3 Functions of may        (a) They are permitted to leave the next day.  (b) It is possible they will leave the next day.  They may leave tomorrow. 4 Functions of may        (a) *They are permitted to betray us.   (b) It is possible they will betray us.  They may betray us. 5 Functions of must       (a) We are able to cross the river. (Old English)  (b) We have to cross the river.  We must cross the river. We must cross the river before the rain comes. 6 Functions of must       (a) She has to be here. (obligation: she has no choice)   (b) She has to be here. (logical conclusion: the evidence is such)  She must be here. She must be here. Gran’s the only one she’d turn to when she’s in trouble. 7 Students sometimes wonder and ask:    How come these modals have so many functions? 8 Is there a learnability problem?   Given that many modals have multiple functions, how do learners acquire these various form-function mappings?   (Extended) Vygotskyan approach:  SOCIAL ACTIVITIES > Consolidation of form-function mappings through frequent use > Attention to form > Pattern recognition > Creative play   Formal Instruction: Focus on form   Grammar Story approach: Focus on form + Play    9 Our present focus   The story of how modals acquire new functions over time.  We first focus on the functions of can.  Then we compare its fuctions with those of may and must.  We highlight some robust diachronic patterns:  Deontic > epistemic uses   Paradigmatic change—structural analogy  ‘Cyclical’ (or rather ‘wave-like’)—in the sense that the semantic extensions are renewable, albeit through recruitment of new grammatical items/constructions  Crosslinguistically robust (Bybee, Perkins & Pagliuca 1994; Traugott & Dasher 2002)  10 Table 1.

(1)  a.  He can speak three languages.   (mental ability)        b.  I can swim.     (physical ability)        c.  Smoking can cause cancer.   (root possibility)    d.  Can I use your computer?   (permission)        e.  That can’t be the time!    (epistemic meaning)   Present-day English can derives from Old English cunnan ‘to know (how to), to be mentally/intellectually able to’.  15 Old English Period (5th century-1066)     The present form of Old English cunnan was cannn (> PDE can).   Its preterit (past) form was cūðe (> PDE could).    Cunnan in OE functions primarily as a transitive verb meaning ‘to know’   (Tanaka 1990: 91).   (2)   a.  Ic hine cupe cnihtwesende    (Beowulf, cited in Klaeber 1922: 372)   ‘Ί knew him when he was a youth’       b.  men ne cunnon,    hwyder helrunan hwyrftum scriþað   (Beowulf, cited in Klaeber 1922: 162)     ‘men know not    where such mysterious creatures of hell go in their wanderings’   16 OE cunnan can also be used with an infinitive, meaning ‘to know how to’.    (3)    a. Men ne cunnon secgan to soðe   (Beowulf, cited in Klaeber 1922: 50)   ‘Men know not how to say truly’      b.  him bebeorgan ne con    (Beowulf, cited in Klaeber 1922: 1746)   ‘He knows not how to defend himself’    In other words, OE cunnan expresses mental ability, i.e. the power to learn or retain knowledge. 17 Middle English (1066-1476)    Around 1300, can was found with predicates requiring physical ability   (i.e. the ability to perform some physical act) (Bybee et al. 1994: 192).    Can was extended to all types of activities and express general ability   (i.e. meaning ‘to be able’).   (4)    a.  So yung þat sho ne couþe Gon on fote.   Havelok III (c. 1300)          b.  I kan nat love a coward, by my feith!   The Nun’s Tale, line 91           (late 14th c.)       c.  To can renne withe speer.     Bk. Noblesse 76 (1475)          d.  Sum off yaim couth swome full weill.     J. Barbour Bruce (Adv.) III. 431           [1489 (1380)]   18 Mental ability + physical ability      general ability    Bybee et al. (1994: 192) suggest that can is often used where both mental and physical ability are required, since ‘most activities that require mental ability also require some physical ability’.    19 Modern English Period (1476-present)    In Early Modern English, can expressing ability was further extended to indicate root possibility.  (5)   a.  Thou cannest not haue of Phocion a frende & a flaterer bothe to gether.        N. Udall tr. Erasmus Apophthegmes 299a (1542)           b.  And can you blame them? P. Stubbes         Second Pt. Anat. Abuses sig. F5 (1583)      c.  Ye cannot drink the cup of the Lord, and the cup of devils.        Bible (A.V.) 1 Cor.x.21 (1611)           d.  You can hardly over-water your Strawberry-Beds.        J.Evelyn Kalendarium Hortense (ed.8) 33 (1691)   20 Ability  >  Root Possibility   How does the change from ability to root possibility happen?    According to Bybee, Perkins & Pagliuca (1994), the agent’s ability to perform an act is determined not only by the agent, but also by the external world.    For example, I can ride that horse, the agent’s ability to ride that horse depends not only on the agent’s ability, but also on the properties of the horse, since ‘horse can be more or less difficult to ride’.    Can indicating ability was then extended to ‘predicate all sorts of enabling conditions – those internal to the agent as well as external conditions’ (Bybee et al. 1994: 192).  21 Can is associated with less formal registers   Early 16th century   Can indicating possibility was favoured in colloquial registers ‘in particular, in texts close to spoken language, such as diaries, private correspondence, trials and, to some extent, sermons’ (Rissanen 1999: 237-238)    16th & 17th century  Can indicating possibility gains ground at the expense of may.  22 Root possibility  >  epistemic necessity   In early Modern English, can also developed an epistemic meaning.   However, the epistemic use of can only occurs in negations and interrogations (Rissanen 1999: 237).  (6)  a.  This cannot be but a great folly.               ([HC] Brinsley 45)      b.  And Nicodemus answered and sayde vnto him:    how can these thinges be?          ([HC] Tyndale John 3.9)  23 Could as a modal expressing epistemic necessity   In Present-Day English (PDE), can still cannot express epistemic meaning in assertions.    It is often the past form could that indicates epistemic meaning.   (7)   a. There could be something wrong with the light switch.           (Quirk et al. 1985: 233)          b. This could be the all important round.            (S.10.3.99 from Palmer 1990: 185)   24 Hypothetical possibility  >  epistemic possibility   According to Goossens (1996: 15), the epistemic use of could derived from its hypothetical possibility use, which arose in Middle English (Andrews 1993: 38).    (8) So god as gawayn gaynly is halden,           And cortaysyse is closed so clene in hymseluen,   Couth not lyзtly haf lenged so long with a lady   Bot he had craued a cosse bi his courtaysye …                                  (Sir Gawain 2420, Andrews 1993: 42)      ‘As gallant as Gawain rightly is considered,    If chivalry is contained so completely in himself,    [He] could not easily have lingered so long with a lady    Unless he had craved a kiss for his courtesy …’ 25 Hypothetical possibility  >  epistemic possibility  (9) a.  but that I am forbid…  I could a tale vnfolde whose lightest word  Would harrow vp they soule,                           (Hamlet 630, Andrews 1993: 44)        b.   you could for a neede study a speech of some dosen or   sixteene lines, which I would set downe and insert in’t,  could ye not?                                  (Hamlet 1471-3, Andrews 1993: 44)        c.  Had I but time, as this fell sergeant Death  Is strict in his arrest, o I could tell you                             (Hamlet 3555-6, , Andrews 1993: 44)  26 Hypothetical possibility  >  epistemic possibility   Goossens (1996: 15) proposes that ‘hypothetical possibility gradually shades off into epistemic’ and provides a hypothetical context below in which could can mean ‘perhaps’.   (10)  … and considering that the trip was too sharp for such   a big horse as this handsome son of le Sage he has   acquitted himself extremely well. Sagacity could be the  one to give Pinturischio most to do if they meet next  Thursday.      (A32, 66-70 from Goossens 1996: 15)  27 Permission (19th century)   The use of can indicating permission is a 19th-century development (Traugott 1989:36; Rissanen 1999:237).  The following examples are from the OED.   (11) a. Can I speak with the Count?                (Falcon, Tennyson 1879)         b. Father says you can come.           (Dog with Bad Name, , xv.156 , T.B. Reed 1894)         c. No one can play the organ during service time   without the consent of the Vicar.       (Church Times 3 Feb. 136/3, 1905)  28 Root possibility  >  Permission   According to Bybee et al. (1994: 193), the permission use of can developed out of its root possibility use as in (5).    They also suggest that the permission use can be regarded as a special instance of root possibility, since ‘The general enabling conditions expressed by root possibility include both physical conditions and social conditions, and permission is simply the presence of social enabling conditions’.  29     SOCIAL DOMAIN Figure 1.
