AbstractClauses can show closest-conjunct agreement, where the verb agrees only with one conjunct of a conjoined subject, and not with the full conjoined subject. The aim of this study is to examine the properties of word order and closest-conjunct agreement in the Greek Septuagint to distinguish which of them are due to the native syntax of Koiné Greek, possibly influenced by contact with Hebrew, and which of them are the result of a biblical translation effect. Both VSO and closest-conjunct agreement in the case of postverbal subjects have been considered characteristics of Biblical Hebrew. VSO becomes a neutral word order for Koiné Greek, and Koiné Greek exhibits examples of closest-conjunct agreement as well. The present study shows that VSO is the neutral word order for various types of texts of Koiné Greek (biblical and non-biblical, translations and non-translations) and that closest-conjunct agreement is also present with similar characteristics in pre-Koiné Greek. All relevant characteristics reflect a type of a syntactic change in Greek related to the properties of the T domain, and evidenced not only in translations or Biblical Greek. However, the frequencies of word orders are indeed affected by the source language, and indirect translation effects are evident in the Greek Septuagint.
