These interpretations and findings are presented consistently throughout the book, with an emphasis on four major registers (functional styles), conversation, fiction, news, and academic prose, occasionally supplemented by examples from two supplementary registers: general prose (non-fiction) and non-conversational speech (e.g. lectures, sermons). Covering both British and American varieties of English in all of these registers but the last one,[1] the descriptions in LGSWE are based on a language corpus exceeding 40 million words and as such this grammar has been widely praised as a new milestone in corpus-based grammatical studies.[2]
