2; see n. 9) It may equally happen that the laryngeal is dropped and the verb is treated like a -V final verb, according to the paradigms in (12, 13): (15) a. b. simii-t ' I heard' (analogous to ligii-t above), dabeet ' I slaughtered' (like maſ eet) bism-o 'they hear' (like bilg-o) Note in this case that the shift to the vowel-final verb class is complete. This can be seen in the type of stem which the perfect verb assumes. ), the laryngeal-less form shifts to high stem vowel verbs like ligi 'get'.

The only indices I have used for these two variables are token indices. While the number of lexical types is relatively small (33), the number of tokens can be large because this vowel alternation is found in certain stems of high frequency, like xidime 'work'. As always in this study, the variables represent only those items or contexts in which the variation described above was observed. This means that the verb stem fihim 'understand', a fairly frequent one in texts, was not included among the statistics, even though it has the CHCHG vowel sequence, and clearly belongs to a verbal form class roughly possessing the meaning of stativity, exemplified above with kibir ~ kubur 'grow up', where the i ~  variation is very common, if not the rule.

Before a C-initial suffix (whether the  belongs to subject or object suffix) the final laryngeal is nearly always deleted and the verb falls among the vowel-final class (15a). Before a Vinitial suffix there is a slight tendency for the laryngeal to be deleted (15b), though retention (14b) is also quite common. The total frequencies are as follows: (18) final laryngeal: C-suffix V-suffix retained 11 283 deleted 239 306 Summarizing the results from a systematic standpoint, the laryngeal-final verbs have two options, one paradigm consistent, one paradigm split.
