This article explores event nominals in Mēbengokre, a Jê language spoken in the eastern Amazon region in Brazil. On the basis of data from this language, the article argues that event nouns are more basic than the verbs to which they are related, and develops an account of event nominals where a process of nominalization does not play a part. Though it is conceded that derivation from fully-fledged verbs to nouns and from non-eventive nouns to verbs generally exists in language, it is claimed that embedding of categories under other categories is a marked option that is only analytically justified when there is syntactic evidence of grammatical category mixing.

Deverbal nouns are often referred to as hybrids, containing both verbal and nominal features. In many languages deverbal nouns tend to develop into what Vendler (1967) called perfect nouns. Various stages of this development in Norwegian are proposed, drawing on Grammaticalization Theory and Lexicalization Theory. Frequency data are provided from a large newspaper corpus. The deverbal nouns are analyzed as going through a process of lexicalization where reduction in compositionality, reduced token frequency and increased idiosyncrasy are central elements. This process is triggered by relevance to the root, language use, isomorphism and the maximal difference principle. The article shows that Norwegian deverbal nouns are in a state of flux and that even different members of the same morphological type may behave quite differently syntactically and semantically.
