106 THE ASPECT OF CAUSAT2VITY IN NZEMA • •• • '. • • • • '• , ' • • by . ' •• : ::- . -, .. Isaac K. Chinebuah* . The deacriptive term 'aspect'is notlonally defined by Quirk, ft. at al. (1972s 90) as -the manner in which the verb action is regarded or experienced" such that "the choice of aspect is a comment on or a particular view of the action". And in many languages the term refers to a variety of notions which includes completion, duration and similar concepts. A grammatical category such as aspect may be expressible in notional terms as in the above quotation but as a category of grammar it is established on formal, not on notional grounds In my previous paper on "The Aspect of Stativity In Nzcma", it was mentioned that of the three interrelated aspectual features of t. Ingressivity, 2. Stativity and 3. Causativity that may be set up for a description of the verb phrase, the first is unique in being characterized by the presence or absence of a specific morpheme or prefix (i.e. 1. ka 'to go .1 or 2. ba 'to come {In (in order) order) to. ') in the verb word. This paper deals with the formal characteristics of causativity as an instance, other than stativity, of an aspectual feature that is not exclusively expounded by a specific porpheme. 'to eroaud come and. to. or 'to or The aspectual feature of causativity, with its two terms: causative/non-causative, is set up to handle pairs of verb words that may occur in related pairs of (A) complex semi- transitive and semi-transitive clauses, (B) ditransitive and transitive clauses and (C) transitive and intransitive clauses Such pairs of verb words may be (a) verbal forms morphologica1 ly and/or phonologically related, (b) identical in shape or (c) different lexical items. (A) Complex semi-transitive and semi-transitive clauses The two pairs of verbal forms 1. fold 'to make climb\/fo climb 'a*d2.benla 'to sit'/cfe 'to be sitting' illustrate of the ways in which corresponding (a) comp(lex) semi- •to one transitive and (b) semi-transitive clauses may be related by means of the aspect of causativity: * Senior Research Fellow, I.A.S., University of Ghana Legon -r- •>••• -3© 107 (1a) \4fei/e £dVq^ Kofi ^ ne azo (Akyc ttiakes Kofi climb on to the table) (comp. semi-transitiva, causative, dynamic) (1b) Kcefl. £& zkponle ne a no (Kofi c"iitabs on to the table) (semi-transitive, non- causative, dynamic) .(2a) Akyc (Akyt Kofi i'k\onl& ne azo Kofi on the table) (comp. semi-transitive, causative, dynamic (2b) Kofi He tkponle ne aso (Kofi is sitting on the table) (semi-transitive, non- causative, stative) In the above examples, the clauses in each pair are syntactically (as wel! as semantically) related in such a way that the object noun phrase (denoting the affected participant) in each (a) complex semi-trangltlve clause recurs as the subject noun phrase.(denoting the agentive participant) in the corresponding (b) sami-transitive clause. The verbal forms in the (b) clauses, which may be re- garded as the verb steins, are morphologically related by suffixation to the verbal forms occurring in the correspond- ing (a) clauses. And in the case of (2a-b) the verbal form in (2b) is additionally related phonologically by stem-initial consonant mutation (i.e. t/d) to the verbal form in (2a). In respect of the number of places requisJid by the verbal form in each pair, the suffixed verbal form occurring in each complex semi-transitive clause requires three places, whereas the corresponding verbal form occurring in the related semi- transitive clause is a two-place verb stem. It is further to be noted that the suffixed verbal forms occurring in the (a) clauses are of dynamic aspect, whereas the verb stems occurring in the corresponding (b) clauses may be either of dynamic aspect as in (1b) or of stative aspect as in (2b) . And semantically, we might say that there obtains a cause-and-effeet relationship between the (a) clauses and the (b) clauses such that the verb actidn of the (a) clauses implies or results in the verb action of the (b) clauses. '•V of- A »•* v= * *• 108 On these 'morphosyntactic' as well as semantic grounds, we account the three-place, suffixed verbal forms occurring in the (a) complex semi-transitive clauses as causative, in contradistinction to the two- place verbal forms occurring in the (b) semi-transi- tive clauses which are regarded as non-causative. And we shall term the causative relationship fexempli- fied in (1-2 (a-bjjabove which is characterized by the morphological process of suffixation as morpholo- giaal aaueativization. . . Other pairs of morphological causatives capable of occurring in complex semi-transitive and semi- transitive clauses that may be related in terms of the causative/non-causatiye distinction are: (1) dwuta •to make descend'/dxSu 'to descend' and (2) gyinla 'to stop'/gyi 'to be standing*, of which both members of the first pair are dynamic, whereas those of the se- cond pair contrast in terms of the dynamic/stative distinction• By analogy with (1-2(a-b))above, the dynamic (i.e. kenda 'to hang up')/stative (i.e. henda 'to be hanging') pair of verbal forms occurring in the ing .pair of clauses between which the same syntactic (and semantic) relationship holds may be handled in terms of the causative/non-causative distinction: follow- (3a) Akyi ehenda zdanli ne nyimd ne dzo (Akye has hung the cloth on the line) (3b) edanli ne hSnda nytmd ne dzo (the cloth is hanging on the line) (coup. semi-transi- tive, causative, dynamic) Csemi-transit tive, non- causative, stative) It is to be noted that the pair of verbal forms are identical in morphological shape but that the non-» causative, stative verbal form in the continuative tense occurring in (3b) is phonologically related by stem-initial consonant mutation to the corresponding • ** 109 causative, dynamic, verbal form in the perfect tense ocur- ring in (3a). By contrast with the cases of;morphological causativization exemplified in (1-2 (a-b)) , the causative/ non-causative relationship manifest in such instances as (3a-b) is" provisionally termed as pho'ho logical causativiza- tion . And it is a characteristic feature of phonological causativizatidn that the perfect tense form of the causa- tive, dynamic verbal form implies the continuative tense form of the non-causative, stative verbal form and that this relationship of implication or cause-and-effect re- lationship is phonologically marked by the common feature of stem-initial consonant mutation. In. other instances of phonological causativization, the causative verbal form may be a verbal group (e.g. fa fea 'to take and hide') of which the principal (or first) member is usually the agentive verb fa Ito take' and the auxiliary (or second) member (i.e. fea 'to hide1) is the dynamic verbal form of the phonologically-related, non- causative, stative verbal form (i.e. yea 'to be hidden'),as in (4a) Akyt %va edanlt ne zvea esumi ne 'abo (comp. semi- (Akye has hidden the cloth under the transitive, pillow) causative, dynamic) (4b) tdanlt ne vA
