INTRODUCTION We describe a fairly comprehensive handling of the syntax and semantics of comparative constructions. The analysis is largely based on the theory developed by Pinkham but we advance arguments to support a different handling of phrasal comparatives - in particular we use direct interpretation instead of C-ellipsis. We explain the reasons for dividing comparative sentences into different categories and for each category we give an example of the corresponding Montague semantics. The ideas have all been implemented within a large-scale grammar for Swedish. This paper is written with two distinct audiences in mind. On the practical side we try to present a cookbook which the natural language interface implementor can use ữ he wishes to incorporate comparative constructions into his system s coverage. This is we trust interesting in itself a quick glance at Table 1 should be enough to show that this construction is more common than is perhaps generally realized. Thus in addition to the obvious more less and as much as used together with an adjective adverb or determiner we also include such words as same before and after used in appropriate ways. We also try to give a usable classification of the various kinds of constructions generally lumped together under the blanket heading of Comparative Ellipsis .
