A Grammar of Old English, Volume Morphology completes Richard M. Hogg's two-volume analysis of the sounds and grammatical forms of the Old English language.
Along the scale of Old English grammars, this is not a work intended as a pedagogical introduction to the language (for which Hasenfratz or Baker are both recommended), nor as a reference and philological grammar (e.g. Wright, Campbell, or Quirk & Wrenn); rather, like its companion piece on Old English phonology, also by Richard Hogg, what this work absolutely excels at is providing a thorough, in-depth, and detailed study of its subject matter. Old English morphology is here examined from a thoroughly historical and philological perspective, focusing both on diachronic origins and synchronic developments and variations; it is highly recommended as an advanced work of (more or less) up-to-date Old English linguistic work, and extremely useful and informative.
