Secondary grammaticalization and the English adverbial -ly suffix

Abstract

This paper discusses the secondary grammaticalization of the English adverbial -ly suffix and makes claims about the concept of secondary grammaticalization. Secondary grammaticalization is defined as the development of a new grammatical function in an already grammatical element. It is shown that the development of the -ly suffix involves a number of the processes which are associated with grammaticalization, e.g. paradigmatization, specialization, obligatorification, subjectification, layering and persistence. However, none of these processes seem to be exclusive to secondary grammaticalization, as the process is defined here. It is argued that the concept of grammaticalization should be redefined, and some possible definitions are suggested. It is also suggested that future studies should divide grammaticalization processes into types according to the nature of the target element, as suggested by Kranich (this issue). Such an approach may perhaps uncover categorical differences between different types of grammaticalization processes.Another important claim is that the concept of obligatoriness should include both language internal obligatoriness and communicative obligatoriness, where the latter also includes socially determined obligatoriness. Further, the concept of paradigmaticity should include the opposition of social variants.
