English displays a variety of complex properties in comparatives. In particular, it employs three main types of comparatives: comparative total-deletion (CTD), comparative subdeletion (CSD), partitive comparative deletion (PCD). In this paper, we first look into the grammatical properties of these three types of comparatives in English and provide a construction-based perspective with the mechanism of inheritance. This perspective, allowing us to tease part the similarities and differences among the three types of comparatives, can provide us a reasonable way to explain the phenomena in question.
