Although 'stance' and 'evaluation' are closely related theoretical constructs, stance is normally investigated through corpus-based methods focusing on the use of lexico-grammatical features, while evaluative language, being regarded as more context-dependent, has been investigated through the use of particular words and phrases in individual texts. This study explores the possibility that these two linguistic systems are partially complementary, with some registers relying on lexico-grammatical stance features and others on evaluative lexis. We compare the linguistic discourse styles of three opinionated/persuasive web registers: 'Opinion Blogs' (OB), 'Reviews' (RV), and 'Descriptions-with-intentto- Sell' (DS). We show that OB and RV use grammatical stance devices more but DS considerably less than most other web registers. However, our detailed study of the lexical keywords found in these three registers reveals the opposite pattern of use.
