This study tackles the neglected subject of word order in biblical Hebrew poetry. The fact that the order of clause constituents frequently differs from that found in prose has often been noted, but no systematic attempt has been offered by way of explanation. Here two separate factors are taken into consideration, that of purely poetic variation (defamiliarisation), and that of pragmatic markedness. The former is common to the poetic genre.

Here the common phenomenon of parallelism is seen to be an important factor in providing a secondary line in which defamiliarisation may freely occuThis work offers a new approach to the poetry of the Old Testament that will be an aid towards more accurate translation, exegesis, and discourse analysis of poetic texts.
