Motivation: |

a. Ourso (1989) In the progressive formation, k-deletion creates the
right environment for the deletion of the vowel /u/ in the CVm roots (i hom-ku
--> i hom-u).
If the vowel /u/ deletes in the progressive form, the infinitive
and the progressive forms of the CVm verbs will be structurally the same
at the surface representation (ho^m 'to pull' & *i ho^m 'he is pulling').
Metathesis is motivated by the nondeletion of the progressive
sufixal vowel which cannot attach to the root final labial /m/ as evidenced
by the behavior of the infinitive suffix 'u'.
|
|
Additional information: |
|
a. /k/ deletion: The velar stop of the suffix deletes after a root final
unrounded vowel or a root final consonant.
