This book presents a new perspective on the interaction between word-order and grammaticalisation by investigating the changes that stylistic fronting and oblique subjects have undergone in Romance (Catalan, French, Spanish) as compared to Germanic (English, Icelandic). It discusses a great deal of historical comparative data showing that stylistic fronting and oblique subjects have (had) a semantic effect in the Germanic and in the Romance languages, and that they both appear in the same functional category.
