摘要：In this article we consider the nature of infixes and whether it is possible to explain their position in a configurational theory of word formation. We argue that in Spanish the elements called infixes are actually two different kinds of entities with different characteristics. The first class of infixes corresponds to a syntactic head and, in consequence, induces a systematic and predictable reading to the base it selects. The second class of infixes is part of certain contextually conditioned allomorphs of the base; as these infixes are subject to Late Insertion, they can only induce conceptual (and, therefore, idiosyncratic) meaning differences.
