Distinguished by a remarkable combination of erudition and lucidity, Aspects of Old English Poetic Syntax provides new insight into the rules that govern syntactic relationships and indicates how these rules differ for prose and verse. Blockley considers the functions of four of the most common and most syntactically important words in Old English, as well as such features of clauses as verb-initial order, negative contraction, and unexpressed but understood subjects. Picking up where Bruce Mitchell's classic Old English Syntax left off, Blockley shows how such common words and structures mark the relationships between phrases and clauses.

Blockley also considers how the poetic tradition compensated for the loss in written texts of the syntactic functions served by intonation and inflection. Arguing that verse relied instead on a prescriptively regulated, unambiguous syntax, she suggests principles that promise more complex and subtle interpretations of familiar texts such as Beowulf as well as a wealth of other Old English writings.
