by R.M.W. Dixon
Part of a three-volume magnum opus on linguistic description and typology from one of Australia's leading linguists. The series is destined to become the guide to writing descriptive grammars.
Despite "theory" in the title, this could better be described as "anti-theoretical", with Dixon's characteristic dig at linguists who do theory first.
I'm almost finished this volume and about to start Volume 2: Grammatical Topics.
