This study examined written/formal register based on happilyever-after women's fiction conventional blurbs. In particular, the 80 blurbs were equally divided into two types: the classic and mass-marketed. Biber et al. (2021) was used as the framework to extract features to respond to the two research questions: What were the top written/formal features among the classic and mass-marketed happily-ever-after women's novel blurbs? And, which blurb type displayed more resemblance to written/formal register? The functional framework comprised three main groups of features: The passives, adjectivals and adverbials. Results revealed that the first two showed a strong tendency towards written/formal register while the last seemed to show the opposite but was taken here to be in-between features, corresponding to fiction language. The top written/formal features based on the two types of blurbs were the passives (both the full and reduced forms) (26%), full relative clauses (23%), full adverbial clauses (20%) and attributives (13%). The blurb type that seemed inclined towards written/formal nature more was the classic, as substantiated by five salient features: the passives, attributives, -en adjectivals, -ing adverbials and -en adverbials. It is believed that discourse analysts and ESL/EFL teachers can pay more attention to these useful syntactic features, particularly the full and reduced forms, as ways to compress information in formal writing.
