This monograph exemplifies a trend in grammatical theory in which researchers combine findings from more than one area of linguistics. Specifically, the author looks at the relationship between phrasal prominence and focus in Romance and Germanic languages to provide insights into how these properties are grammatically articulated. Building upon prominence (nuclear stress) reflects syntactic ordering. There are two varieties of syntatic ordering. The first is the standard asymmetric c-command ordering. The second is the ordering derived from the primitive relation of selection holding between a head and its associated argument. Part of the difference between Germanic and Romance languages stems from a difference in the way the two syntactic orderings interact in the mapping onto phrasal prominence. The author shows that the symmetry between syntactic ordering and phrasal prominence so defined may be broken because of the independent requirement that a focused constituent must contain the most prominent element in the sentence. Two kinds of processes come into play to repair the broken symmetry. One is a process of deaccenting. The other is a process of movement, called "p-movement". The author shows that an understanding of the properties of p-movement can be attained within the framework of the Minimalist Program.
