Editing Mbula language (section)

===Derivational morphology===
The following types of derivation occur in Mbula: compounding of nouns and verbs, creation of nouns by means other than compounding, derivational devices which alter the transitivity of verbs, [[reduplication]] and some other minor processes. Compounding is not a very productive process in Mbula though is far more common in verbs than in nouns. Verbs can compound with adverbs, nouns and other verbs to create verbs. Nouns are more likely to be derived by the nominalising suffix {{lang|mna|-nga}}. When combined with adverbs it yields stative nouns; with nouns it can either signal an intensification of meaning or a slight change in meaning (with no intensification); it turns stative verbs into stative nouns and dynamic verbs into nouns. Semantically, {{lang|mna|-nga}} derivations tend to convey the idea of generic, habitual or characteristic actions. A further nominalisation suffix {{lang|mna|-i}} exists but is far less productive than {{lang|mna|-nga}}. Transitivity of predicates can be altered by the addition of one or more of the following prefixes: {{lang|mna|pa}}, {{lang|mna|par}}, and {{lang|mna|m}}, and these are extremely productive processes. Finally, reduplication can result in any one of the following meanings: plurality, distribution, intensification, diminution or habitual-durative action (action that is somehow extended).
