the action or the persons involved in the action. A
special kind of derivation is nominalization, which
changes a verb root or stem to a noun theme. The suf-
fixes that nominalize verbs are discussed in 7-4.2 as they
are used in morphosyntactic subordination. Verbal in-
flectional suffixes indicate person and tense, and these
suffixes close verb stems to further derivation. Verbal
inflectional suffixes may be separated from derivational
suffixes by the class of independent nonfinal suffixes
that occur on both nouns and verbs.

Verbs of carrying and placing belong to covert
classes according to manner of motion and attributes
of the item moved (Tate 1970). Some examples from La

Paz are included in the elicitation list, Appendix A.

6-2 Verbal Derivational Suffixes

The basic data and analysis on which this section

is based were provided by England (Hardman et al. 1975:
3.148-208) and have been supplemented by my analysis

of additional data obtained in my field work and from
Bertonio (1603b); see Figure 6-1. Class 1 suffixes
affect the action of the verb (e. g., its direction,
intensity, duration) and are tied to the selection of

its zero complements. Class 2 suffixes affect the in-
flection (the persons involved in the action and/or the

tense or aspect of the verb). Suffixes occurring on the
