368 6-2.25.2 -xa- ~ -ga- completive In view of the /k/ ~ /j/ alternation for the in- completive, the possibility that a similar alternation of /q/ ~ /x/ exists for the completive--or may have existed in the past--must be kept in mind. Tschopik (1948:109) gives one example of a /q/ which is probably a variant of this suffix, but /-xa-/ also occurs in his transcrip- tion, which in any case is not completely phonemic. In Calacala there occurred a /q/ which may be a realiza- tion of the completive. It could not be -qga- 'down', as it occurred after the causative suffix -ya- ~ -:- (here reduced to plain vowel). Amu.s.t'a.q.i.lla. 'He made him be quiet. ' 333 S The Compi equivalent of the above has /-xa-/ (see 6-2.22). Further investigation will be needed to see if /-qga-/ completive is a productive suffix in Calacala and else- where. Examples of the completive are given below with different tenses. Simple: Chur.x.t.wa. ‘I've already given it to him.' give 143 (La Paz)
