This paper presents the first proper syntactic treebank for Akkadian, an ancient Semitic language which can only be reconstructed from its textual data. We introduce our corpus of early Neo-Assyrian royal inscriptions, present some typical syntactic constructions of this genre and discuss the morphological and syntactic choices we have made. For developing a gold standard for morphological annotations, we tested the manually annotated material against BabyFST, a morphological analyzer of Akkadian. We also tested the reproducibility of the syntactic annotations using the TurkuNLP neural parser.
