and conditional clauses. The same object and subject morphemes are used, while the third person is not expressed. There is also a semantically abstract 'mood' marker used to connect clauses that are both coordinated and subordinated. Verb Derivation Verbal derivation in Kwaza includes valency and valency change, negation, modality, aspect, and tense which are marked with various optional verbal morphemes. Some modality morphemes, according to van der Voort, could be grammatically related to mood markers. Verbs can be turned into adverbs or nouns through stem-final nominalizing morphemes. Kwaza has two subdivisions of derivational morphemes, directional and classifiers. While verb morphology in Kwaza is complex, nominal morphology is not. Kwaza has no gender or number inflection. Nouns can have animate object case marking. They can also have one of the oblique case markers: beneficiary, locative, comitative, and instrumental. Nouns are turned into verbs through attaching mood marking. As mentioned, Kwaza does not have adjectives. Nouns and Classifiers Attributive modification of nouns occurs by comparing them with other nouns. Kwaza also has many classifying morphemes that only 'agree' with specific nouns. Classifiers are used widely. They can be used in verb stems, attach to bare nouns, and also modify adverbs. Classifiers are used in the position of nominalizers. Classifiers in Kwaza support van der Voorts statement of the language being pro-drop as they have functions similar to the functions of verbal agreement morphemes. These properties of classifiers rely heavily on the environment in which they are used, and according to van der Voort are not as dynamic as the properties of cross-reference morphemes. In complex nominalized clauses, specific classifiers cannot replace the nominalizer. Morphological Aspect: Morpheme -ry- In the Kwaza language, the morpheme -ry- is used to describe a grammatical number for words in contexts where a few of their referents are described or referred to, also known as paucal. In both nouns and verbs of Kwaza, the morpheme -ry- is associated with paucal number, but does not occur in word-final position, and is always followed by a nominaliser (formation of a noun from a verb or adjective). For example: It is also important to note that the paucal morpheme -ry- applies only to humans and animals in Kwaza. For example: Negation Morpheme -he- In Kwaza, the morpheme -he- is one of the negation morphemes, which creates the negative in predicates and propositions when bound together. In this negation morpheme, the negative
