Editing Instrumental case (section)

===Ancient Greek===
The functions of the [[Proto-Indo-European language|Proto-Indo-European]] instrumental case were taken over by the [[dative case|dative]], so that the Greek dative has functions belonging to the Proto-Indo-European dative, instrumental, and [[locative case|locative]].<ref>[[Herbert Weir Smyth]]. ''Greek Grammar''. par. 1279: composite or mixed cases.</ref> This is the case with the bare dative, and the dative with the preposition [[wikt:σύν#Ancient Greek|σύν]] ''sýn'' "with". It is possible, however, that Mycenean Greek had the instrumental case, which was later replaced by dative in all the [[Ancient Greek dialects|Greek dialects]].<ref>[[Andrew Garrett (linguist)|Andrew Garett]], "Convergence in the formation of Indo-European subgroups: Phylogeny and chronology", in Phylogenetic methods and the prehistory of languages, ed. Peter Forster and Colin Renfrew (Cambridge: McDonald Institute for Archaeological Research), 2006, p. 140, citing Ivo Hajnal, Studien zum mykenischen Kasussystem. Berlin, 1995, with the proviso that "the Mycenaean case system is still controversial in part".</ref>
