In Ancient Greek, as well as in other languages, whenever agreement is triggered by
two or more coordinated phrases, two different constructions are allowed: either the
agreement can be controlled by the coordinated phrase as a whole, or it can be triggered
by just one of the coordinated words. In spite of the amount of information that can be
read on this topic in grammars of Ancient Greek, much is still to be known even at a
general descriptive level. More importantly, the data still lack a convincing explanation.
In this paper, we focus on a special domain of agreement (subject and verb agreement)
and on one morphological feature that is expected to covary (number). We discuss
the agreement in number for conjoined phrases, by revising some of the modern
hypotheses with the support of the empirical evidence that can be collected from the
available syntactically annotated corpora of Ancient Greek (treebanks). Results are
interpreted according to syntactic features, cognitive factors and semantic properties
of the coordinated phrases
