Agentive two-place verbs with dative complements (e.g. German helfen '
help', folgen 'follow' are generally assumed to bear a lexical feature
that blocks regular accusative linking for their nonsubject argument
and indicates the selection of the dative case. In the present paper,
it is argued that native selection of two-place verbs is cross-linguis
tically systematic. Evidence for this claim is provided from one group
of two-place verbs with dative complements that are called ''interact
ion verbs.'' It is shown that the Polynesian dative-selecting two-plac
e verbs (''middle verbs'') included in the data of Chung's (1978) inve
stigation show a striking affinity in meaning to two-place verbs with
native complements in four Indo-European languages of different famili
es. This observation seriously challenges any account that treats two-
place verbs with dative complements principally as idiosyncratic. Howe
ver, Kiparsky's (1995) recent proposal to motivate the dative selectio
n of two-place verbs semantically by the homogeneity of the events the
respective verbs denote is rejected. lit the present approach, the ma
rked linking pattern of these verbs is explained in terms of their low
semantic transitivity. I assume that the semantic transitivity of a v
erb with more than one argument is low if the thematic Poles of the ar
guments show no agent-patient asymmetry.
