Similatives are Manners, comparatives are Quantities (except when they aren’t)

Abstract This article proposes a fine-grained semantic analysis of similative and comparative constructions within the framework of Functional Discourse Grammar (FDG). The core idea is that, when used in their prototypical modifying functions, the two types of constructions are built upon two semantic frames that share an identical structure but differ as regards the semantic category that underlies the whole modifying expression – whence the title of the article: similatives are Manners and comparatives are Quantities. At the same time, I argue that similatives can also be put to modifying and predicative uses in which they do not express a Manner but a Configurational Property (i.e., a “nuclear predication”) and that comparatives do not express a Quantity when occurring as arguments of lexical(ized) ditransitive predicates like prefer or would rather, nor when the two terms of the comparison are introduced by a specific type of temporal expression. Finally, the paper refines previous FDG approaches to the alternation between analytic and synthetic expression of comparison in such languages as English and Latin, proposing that the English comparative suffix -er is liable to being modified by narrow-scope measure expressions and is therefore a partly lexical element and not a fully grammaticalized marker of comparison.
