Present-day allomorphs of -jama beginning with /j/ or /k"/ require a preceding consonant; those beginning with vowel length of course require a preceding vowel. Bertonio's inconsistent spelling precludes certainty about the morphophonemics of the allomorphs in his day. The morphophonemics of -nama are variable, sometimes requiring a preceding vowel, sometimes a preceding con- sonant. The various allomorphs keep their final vowels except before /-jama/ itself (which may occur after -nama and may reduplicate on itself) and when zero complement final vowel dropping occurs. 5-3.33 Zero complement vowel drop In Aymara each verb root or stem has many poten- tial zero complements. These are noun roots, stems, or themes whose occurrence with a given verb root or stem depends on semantic constraints inherent in the verb root and in the verbal derivational suffixes which may occur in the verb. As these suffixes change, the zero comple- ments change also. They are called zero complements because they are marked by obligatory loss of the final stem vowel before final sentence suffixes, if any, except -lla ~ -~ya. The loss of vowel may occur on an independent suffix, if any occurs on the noun root, stem,
