A grammatical construction resembling Present-Day English locative inversion has already been found in Old English, with a fronted prepositional phrase prompting V2 word order, both in main and subordinate clauses. It has been demonstrated that several discourse-related factors influence the positioning of objects, fronted locatives, finite verbs and subjects in subordinate clauses. One of the main aims of the present paper is to provide a quantitative and qualitative analysis of the locative inversion construction in Old English subordinate clauses. The Old English data for this study were obtained from the York–Toronto–Helsinki Parsed Corpus of Old English Prose, and they were analysed using Corpus Studio. The results were compared with those for main clauses, and discourse-related factors such as PP anaphoricity or subject type were analysed in order to find the motivation for the existence of this alternation of word orders. PP anaphoricity proved not to be a determining factor in triggering finite verb inversion, while other factors such as subject weight and subject type do seem to motivate finite verb inversion, thus yielding an embedded PP-V-S word order.
