Abstract
The aim of this paper is to reconsider and revise the classification of prefixes and particles added to OE verbs, proposed in Niwa (1991, 1995), comparing it with Hiltunen’s classification and referring to an approach within generative grammar. We argue that (i) prefixes and particles with a prepositional function play as important a role as ones with an adverbial function and that (ii) prefixes added to OE verbs can be subdivided into nonfixed ones and fixed ones. We found that for (i), while Hiltunen disregards it, generative grammar supports it. In the case of (ii), while Hiltunen agrees with it, though using different terms, generative grammar does not allow it on the basis of the principle of economy.
