an interesting and informative study that should appeal to linguistic and cognitive anthropologists, cognitive and historical linguists, and laypersons interested in languages ... Heine presents a plausible explanatory framework and lucid descriptions of a variety of lexical patterns and grammatical constructions in several domains of meaning.
Gary B. Palmer, Cognitive Linguistics, 10-2, 1999.
Wide-ranging the book indeed is ... and its lucid style, coherent focus, and wealth of examples make it an excellent intoduction to the topic and the method that it reprents ... richly informative book ... It can unreservedly be recommended as an introduction to contemporary grammaticalization theory, but it will also be useful and illuminating reading for researchers and students in all areas of cognitive-functional linguistics, and anyone interested in the cognitive foundations of language.
