Haan Germen J. de Haan 
Studies in West Frisian Grammar [PDF ebook] 

In this volume, Germen de Haan gives a multi-faceted view of the syntax, sociolinguistics, and phonology of West-Frisian. The author discusses distinct aspects of the syntax of verbs in Frisian: finiteness and Verb Second, embedded root phenomena, the verbal complex, verbal complementation, and complementizer agreement. Because Frisian has minority language status and is of interest to sociolinguists, the author reviews the linguistic changes in Frisian under the influence of the dominant Dutch language and, more generally, reflects on how to deal with contact-induced change in grammar. Finally, in three phonological articles, the author discusses nasalization in Frisian, the putatively symmetrical vowel inventory of Frisian, and the variation between schwa + sonorant consonants and syllabic sonorant consonants.
